Houston 2017... The eighth geoscience hackathon landed last weekend!

We spent last weekend in hot, humid Houston, hacking away with a crowd of geoscience and technology enthusiasts. Thirty-eight hackers joined us on the top-floor coworking space, Station Houston, for fun and games and code. And tacos.

Here's a rundown of the teams and what they worked on.

Seismic Imagers

Jingbo Liu (CGG), Zohreh Souri (University of Houston).

Tech — DCGAN in Tensorflow, Amazon AWS EC2 compute.

The team looked for patterns that make seismic data different from other images, using a deep convolutional generative adversarial network (DCGAN). Using a seismic volume and a set of 2D lines, they made 121,000 sub-images (tiles) for their training set.

The Young And The RasLAS

William Sanger (Schlumberger), Chance Sanger (Museum of Fine Arts, Houston), Diego Castañeda (Agile), Suman Gautam (Schlumberger), Lanre Aboaba (University of Arkansas).

State of the art text detection by Google Cloud Vision API

State of the art text detection by Google Cloud Vision API

Tech — Google Cloud Vision API, Python flask web app, Scatteract (sort of). Repo on GitHub.

Digitizing well logs is a common industry task, and current methods require a lot of manual intervention. The team's automated pipeline: convert PDF files to images, perform OCR with Google Cloud Vision API to extract headers and log track labels, pick curves using a CNN in TensorFlow. The team implemented the workflow in a Python flask front-end. Check out their slides.

Hutton Rocks

Kamal Hami-Eddine (Paradigm), Didi Ooi (University of Bristol), James Lowell (GeoTeric), Vikram Sen (Anadarko), Dawn Jobe (Aramco).

hutton.png

Tech — Amazon Echo Dot, Amazon AWS (RDS, Lambda).

The team built Hutton, a cloud-based cognitive assistant for gaining more efficient, better insights from geologic data. Project includes integrated cloud-hosted database, interactive web application for uploading new data, and a cognitive assistant for voice queries. Hutton builds upon existing Amazon Alexa skills. Check out their GitHub repo, and slides.

Big data > Big Lore 

Licheng Zhang (CGG), Zhenzhen Zhong (CGG), Justin Gosses (Valador/NASA), Jonathan Parker (Marathon)

The team used machine learning to predict formation tops on wireline logs, which would allow for rapid generation of structure maps for exploration play evaluation, save man hours and assist in difficuly formation-top correlations. The team used the AER Athabasca open dataset of 2193 wells (yay, open data!).

Tech — Jupyter Notebooks, SciPy, scikit-learn. Repo on GitHub.

Free near surface

free_surface.png

Tien-Huei Wang, Jing Wu, Clement Zhang (Schlumberger).

Multiples are a kind of undesired seismic signal and take expensive modeling to remove. The project used machine learning to identify multiples in seismic images. They attempted to use GAN frameworks, but found it difficult to formulate their problem, turning instead to the simpler problem of binary classification. Check out their slides.

Tech — CNN... I don't know the framework.

The Cowboyz

Mingliang Liu, Mohit Ayani, Xiaozheng Lang, Wei Wang (University of Wyoming), Vidal Gonzalez (Universidad Simón Bolívar, Venezuela).

A tight group of researchers joined us from the University of Wyoming at Laramie, and snagged one of the most enthusiastic hackers at the event, a student from Venezuela called Vidal. The team attempted acceleration of geostatistical seismic inversion using TensorFlow, a central theme in Mingliang's research.

Tech — TensorFlow.

Augur.ai

Altay Sensal (Geokinetics), Yan Zaretskiy (Aramco), Ben Lasscock (Geokinetics), Colin Sturm (Apache), Brendon Hall (Enthought).

augur.ai.JPG

Electrical submersible pumps (ESPs) are critical components for oil production. When they fail, they can cause significant down time. Augur.ai provides tools to analyze pump sensor data to predict when pumps when pump are behaving irregularly. Check out their presentation!

Tech — Amazon AWS EC2 and EFS, Plotly Dash, SigOpt, scikit-learn. Repo on GitHub.

disaster_input.png

The Disaster Masters

Joe Kington (Planet), Brendan Sullivan (Chevron), Matthew Bauer (CSM), Michael Harty (Oxy), Johnathan Fry (Chevron)

Hydrologic models predict floodplain flooding, but not local street flooding. Can we predict street flooding from LiDAR elevation data, conditioned with citizen-reported street and house flooding from U-Flood? Maybe! Check out their slides.

Tech — Python geospatial and machine learning stacks: rasterio, shapely, scipy.ndimage, scikit-learn. Repo on GitHub.

The structure does WHAT?!

Chris Ennen (White Oak), Nanne Hemstra (dGB Earth Sciences), Nate Suurmeyer (Shell), Jacob Foshee (Durwella).

Inspired by the concept of an iPhone 'face ageing' app, Nate recruited a team to poke at applying the concept to maps of the subsurface. Think of a simple map of a structural field early in its life, compared to how it looks after years of interpretation and drilling. Maybe we can preview the 'aged' appearance to help plan where best to drill next to reduce uncertainty!

Tech — OpendTect, Azure ML Studio, C#, self-boosting forest cluster. Repo on GitHub.

Thank you!

Massive thanks to our sponsors — including Pioneer Natural Resources — for their part in bringing the event to life!

SEGAM-logo-2017.jpg

The SEG Annual Meeting is coming up. Next week sees the festival of geophysics return to the global energy capital, shaken and damp but undefeated after its recent battle with Hurricane Harvey. Even though Agile will not be at the meeting this year, I wanted to point out some highlights of the week.

The Annual Meeting

The meeting will be big, as usual: 108 talk sessions, and 50 poster and e-presentation sessions. I have no idea how many presentations we're talking about but suffice to say that there's a lot. Naturally, there's a machine learning session, with the following talks:

The Geophysics Hackathon

Even though we're not at the conference, we are in Houston this weekend — for the latest edition of the Geophysics Hackathon! The focus was set to be firmly on 'machine learning', but after the hurricane, we added the theme of 'disaster recovery and mitigation'. People are completely free to choose whatever project they'd like to work on; we'll be ready to help and advise on both topics. We also have some cool gear to play with: a Dell C4130 with 4 x NVIDIA P100s, NVIDIA Jetson TX1s, Amazon Echo Dots, and a Raspberry Shake. Many, many thanks to Dell EMC and Pioneer Natural Resources and all our other sponsors:

If you're one of the 70 or so people coming to this event, I'm looking forward to seeing you there... if you're not, then I'm looking forward to telling you all about it next week.

Petrel User Group

icons-petrel.png

Jacob Foshee and Durwella are hosting a Petrel User Group meetup at The Dogwood, which is in midtown (not far from downtown). If you're a user of Petrel — power user or beginner, it doesn't matter — and you're interested in making the most of technology, it'd be good to see you there. Apart from anything else, you'll get to meet Jacob, who is one of those people with technology superpowers that you never know when you might need.

Rock Physics Reception

Tuesday If you've never been to the famous Rock Physics Reception, then you're missing out. It's your best shot at bumping into the luminaries of rock physics — Colin Sayers, Stefan Gelinsky, Per Avseth, Marco Perez, Bill Goodway, Tad Smith — you know the sort of thing. If the first thing you think about when you wake up in the morning is Lamé's second parameter, RSVP right now. Hurry: there are only a handful of spots left.

There's more! Don't miss:

  • The Women's Network Breakfast on Wednesday.
  • The Wiki Committee meeting on Wednesday, 8:00 am, Hilton Room 344B.
  • If you're an SEG member, you can go to any committee meeting you like! Find one that matches your interests.

If you know of any other events, please drop them in the comments!

 

90 years of well logs

/

Today is the 90th anniversary of the first well log. On 5 September 1927, three men from Schlumberger logged the Diefenbach [sic] well 2905 at Dieffenbach-lès-Wœrth in the Pechelbronn heavy oil field in the Alsace region of France.

Pechelbronn_log_plot.png

The geophysical services company Société de Prospection Électrique (Processes Schlumberger), or PROS, had only formed in July 1926 but already had sixteen employees. Headquartered in Paris at 42, rue Saint-Dominique, the company was attempting to turn its resistivity technology to industrial applications, especially mining and petroleum. Having had success with horizontal surface measurements, the Diefenbach well was the first attempt to measure resistivity in a wellbore. PROS went on to become Schlumberger.

The resistivity prospecting system had been designed by the Schlumberger brothers, Conrad (1878–1936, a professor at École des Mines) and Maurice (1884–1953, a mining engineer), over the period from about 1912 until 1923. The task of adapting the technology was given to Henri Doll (1902–1991), Conrad's son-in-law since 1923, and the Alsatian well was to be the first field test of the so-called "electrical coring" method. The client was Deutsche Erdöl Aktiengesellschaft, now DEA of Hamburg, Germany.

As far as I can tell, the well — despite usually being called "the Pechelbronn well" — was located at the site of a monument at the intersection of Route de Wœrth with Rue de Preuschdorf in Dieffenbach-lès-Wœrth, about 3 km west of Merkwiller-Pechelbronn. Henri Doll logged the well with Roger Jost and Charles Scheibli. Using rudimentary equipment, they logged about 145 m of the 488-metre hole, starting at 279 m MD, taking a reading every metre and plotting the log by hand. Yesterday I digitized this log; download it in LAS format here. 

Pechelbronn_thumbnail.png

The story of what the Schlumberger brothers and Henri Doll achieved is fascinating; I recommend reading Don Hill's brief history (2012) — it's free to read at Wiley. The period of invention that followed the Pechelbronn success was inspiring.

If you're looking at well logs today, take a second to thank Conrad, Maurice, and Henri for their remarkable idea.

PS If you're interested in petroleum history, the AOGHS page This Week is worth a look.

The French television programme Midi en France recorded this segment about the Pechelbronn field in 2014. The narration is in French, "The fields of maize gorge on sunshine, the pumps on petroleum...", but there are some nice pictures to look at.

Another fossil book

/

I'm thrilled to introduce the latest book in the 52 Things series!

52 More Things You Should Know About Palaeontology is out. You can buy it direct from us, on Amazon.com and Amazon.co.uk, and it will soon be available all over the world via Amazon's other stores.

In common with all the books from Agile Libre, it is a scholarly text with some weird features. For example:

  • It's fun and easy to read. Each of the 52 essays is only about 700 words long.
  • It costs $19, not $49 (I am not making that $49 up. Welcome to academic publishing!)
  • It's openly licensed, so you can re-use any of the content with attribution but without permission.
  • $2 from every sale goes to the Society of Vertebrate Paleontology to support their work.

A book for everyone

Like the first 52 Things on fossils, it's not just for palaeontologists. No matter who you are, I hereby guarantee that you'll find something useful and interesting in there, or your money back. I mean, just look at some of these chapters:

  • A closer look at fossil sex, by Benni Bomfleur & Hans Kerp — in flagrante!
  • A snake with four legs, by David Martill — chronic limb loss!
  • Birds of a fibula, by Jon Tennant — dino bones!
  • Fossils for sale, by Tony Doré, OBE, of Statoil — selling shells!
  • Gods and monsters, by Andrew Taylor — miracles!
  • How kangaroos got their bounce, by Benjamin P Kear — just so!
  • Impossible frogs in the Deccan Traps, by Michael Oates — igneous fossils!
  • In search of the Balearian mouse goat, by Alun Williams — mouse goats!
  • Interview with a Triceratops, by John Scanella — dinosaurs forever!
  • Micro-dung and its uses, by Wyn Hughes — tiny poo!
  • Traces in the terrarium, by Daniel Hembree — experimental ichnology!
  • Vertebrate palaeontology: more than fossil bones, by John Hutchinson — see dino run!

A huge thanks to the 50(!) authors of this volume. Together, I estimate they have over 1000 years of experience to share. Imagine that for a moment. All that learning, centuries in the field, decades in the library, or squinting down microscopes... just to write an essay for you! 

Massive thanks as well to Alex Cullum and Allard Martinius, both of Statoil. It takes a good deal of tenacity to rally 50 people to do anything, let alone write a book together... and they've done it twice. And they've nailed it again — check out what Prof David Polly (Indiana), president of the Society of Vertebrate Palaeontology had to say about the book:

“[It] looks fantastic. There is a lot of useful and high-level information in it, plus it is entertaining to read. I’m also pleased to see several SVP members in the author list. It deserves to be a great success. (The other books in the series are equally wonderful... having worked with eigenvectors daily for decades, I nevertheless learned something from Ruelicke’s chapter in the Geology volume.)”

I hope you enjoy the book too!

Have you read 52 Things... Rock Physics? If you enjoyed it, or even if you didn't, we'd love a short review on Amazon.com :) Help spread some geophysics goodness.

Subsurface Hackathon project round-up, part 1

/

The dust has settled from the Hackathon in Paris two weeks ago. Been there, done that, came home with the T-shirt.

In the same random order they presented their 4-minute demos to our panel of esteemed judges, I present a (very) abbreviated round-up of what the teams made together over the course of the weekend. With the exception of a few teams who managed to spontaneously nucleate before the hackathon, most of these teams were comprised of people who had never met each other before the event.

Just let that sink in for a second: teams of mostly mutual strangers built 13 legit machine-learning-based geoscience applications in one weekend. 

Log Healer  

Log Healer

 

 

An automated well log management system

Team Un-well Loggers: James Wanstall (Glencore), Niket Doshi (Teradata), Joseph Taylor (Teradata), Duncan Irving (Teradata), Jane McConnell (Teradata).

Tech: Kylo (NiFi, HDFS, Hive, Spark)

If you're working with well logs, and if you've got lots of them, you've almost certainly got gaps or inaccuracies from curve to curve and from well to well. The team's scalable, automated well-log file management system Log Healer computes missing logs and heals broken ones. Amazing.

An early result from Team Janus. The image on the left is ground truth, that on the right is predicted. Many of the features are present. Not bad for v0.1!

Meaningful cross sections from well logs

Team Janus: Daniel Buse, Johannes Camin, Paul Gabriel, Powei Huang, Fabian Kampe (all from GiGa Infosystems)

The team built an elegant machine learning workflow to attack the very hard problem of creating geologically realistic cross-section from well logs. The validation algorithm compares pixels to score the result.

Paint-by-numbers on digital thin sections

Team Think Section: Diego Castaneda (Agile*), Brendon Hall (Enthought), Roeland Nieboer (Fugro), Jan Niederau (RWTH Aachen), Simon Virgo (RWTH Aachen)

Tech: Python (Scikit Learn, Scikit Image, Flask, NumPy, SciPy, Pandas), AWS for hosting app & Jupyter server.

Description: Mineral classification and point-counting on thin sections can be an incredibly tedious and time consuming task. Team Think Section trained a model to segregate, classify, and label mineral grains in 200GB of high-resolution multi-polarization-angle photomicrographs.

Event detection on seismic shot gathers

Team Classy: Princy Ikotoko Ndong (EOST), Anna Lim (NTNU), Yuriy Ivanov (NTNU), Song Hou (CGG), Justin Gosses (Valador).

Tech: Python (NumPy, Matplotlib), Jupyter notebooks.

The team created an AI which identifies and labels different events on a shot gather image. It can find direct waves, reflections, multiples or coherent noise. It uses a support vector machine for classification, and is simple and fast. 

model2seismic: An entirely new way to do modeling and inversion. Take note: the neural network that made this image knows no physics.

Forward and inverse modeling without the physics

Team GANsters - Lukas Mosser (Imperial), Wouter Kimman (Meridian), Jesper Dramsch (Copenhagen), Alfredo de la Fuente (Wolfram), Steve Purves (Euclidity)

Tech: PyNoddy, homegrown Python ML tools.

The GANsters created a deep-learning image-translation-based seismic inversion and forward modelling system. I urge you to go and look at their project on model2seismic. If it doesn't give you goosebumps, you are geophysically inert.

Team Pick Pick Log

Team Pick Pick Log

Machine learning for for stratigraphic interpretation

Team Pick Pick LOG - Antoine Vanbesien (EOST), Fidèle Degni (Mines St-Étienne), Massinissa Mesbahi (Pau), Natsuki Gunji (Mines St-Étienne), Cédric Menut (EOST).

This team of data science and geoscience undergrads attacked an automated stratigraphic interpretation task. They used supervised learning to determine lithology from well logs in Alberta's Athabasca play, then attempted to teach their AI to pick stratigraphic tops. Impressive!

Pretty amazing, huh? The power of the hackathon to bring a project from barely-even-an-idea to actual-working-code is remarkable! And we're not even halfway through the teams: tomorrow I'll describe the other seven projects. 

Le grand hack!

/

It happened! The Subsurface Hackathon drew to a magnificent close on Sunday, in an intoxicating cloud of code, creativity, coffee, and collaboration. It will take some beating.

Nine months in gestation, the hackathon was on a scale we have not attempted before. Total E&P joined us as co-organizers and made this new reach possible. They also let us use their amazing Booster — a sort of intrapreneurship centre — which was perfect for the event. Their team (thanks especially to Marine and Caroline!) did an amazing job of hosting, as well as providing several professionals from their subsurface software (thanks Jonathan and Yannick!) and data science teams (thanks Victor and David!). Arnaud Rodde and Frédéric Broust, who had to do some organization hacking of their own to make something as weird as a hackathon happen, should be proud of their teams.

Instead of trying to describe the indescribable, here are some photos:

BY THE NUMBERS

16 hours of code
13 teams
62 hackers
44 students
4 robots
568 croissants
0 lost-time incidents

I won't say much about the projects for now. The diversity was high — there were projects in thin section photography, 3D geological modeling, document processing, well log prediction, seismic modeling and inversion, and fault detection. All of the projects included some kind of machine learning, and again there was diversity there, including several deep learning applications. Neural networks are back!

Feel the buzz!

If you are curious, Gram and I recorded a quick podcast and interviewed a few of the teams:

It's going to take a few days to decompress and come down from the high. In a couple of weeks I'll tell you more about the projects themselves, and we'll edit the photos and post the best ones to Flickr (and in the meantime there are a few more pics there already). 

Thank you to the sponsors!

Last thing: we couldn't have done any of this without the support of Dell EMC. David Holmes has been a rock for the hackathon project over the last couple of years, and we appreciate his love of community and code! Thank you too to Duncan and Jane at Teradata, Francois at NVIDIA, Peter and Jon at Amazon AWS, and Gram at Sandstone for all your support. Dear reader: please support these organizations!

Looking forward to EAGE

/

Evan, Diego and I are flying to Paris today for the EAGE Conference and Exhibition. It's exciting. We're excited. 

But the excitement starts before the conference. The Subsurface Hackathon is this weekend!

My diary

Even the hackathon excitement starts before the weekend, because tomorrow, Friday, we're running the hacker's bootcamp — a sort of short course appetizer for the hackathon. We have about 25 geoscientists coming to the Booster TOTAL (an event space at TOTAL's La Défense offices) to get some hands-on practice with Python and the latest in machine learning tools. It's especially exciting because we'll also have engineers from NVIDIA on hand to help with the coaching. The idea is to help people hit the ground running when the hackathon starts on Saturday.

After that, on Saturday and Sunday,  it's the hackathon itself. We have no fewer than 60 geoscientists and engineers registered for this breakout event. They're coming to the Booster to work on a wide array of machine learning ideas for the subsurface. It's going to be epic. You can read all about what happens next week, I promise. 

Then on Monday it's the Data Science for Geoscience workshop, at which I'm giving a keynote. Since I'm far from possessing expertise, I'm using it as a chance to get people jazzed about helping make the coming AI revolution in geoscience a positive experience. I'm really looking forward to it.

The conference itself starts on Tuesday. In the afternoon I'm co-chairing a session on machine learning (have you spotted the theme yet?) in seismic interpretation, along with Victor Aare of Schlumberger. It will be awesome to see what kind of progress our community is making in this field — it's fun to imagine what seismic interpretation might be like in a few years. There are so many fascinating problems to work on! Here are the talks in that session:

On Wednesday we'll be taking in some more talks and posters, then in the afternoon I'm reprising my keynote talk at IFPEN, a subsurface research institute in the Bois de Boulogne. I've never been there before, although I have met a few IFP scientists before. I'm looking forward to it very much. 

It all ends for us on Thursday. Evan and Diego fly home and I'm off to Cambridge (the old one in the fens, not the one in Massachusetts) for a few days with family (and bookshops). Until then, expect much blogging!

Going to EAGE?

If you're reading this and would like to meet up with us at Agile or some of the Software Underground crowd — the friendliest bunch of coding geoscientists you could hope for — let's plan to meet at the end of the workshop, at the workshop location. Look for the Software Underground shirts.

What should national data repositories do?

/

Right now there's a conference happening in Stavanger, Norway: National Data Repository 2017. My friend David Holmes of Dell EMC, a long time supporter of Agile's recent hackathons and general geocomputing infrastructure superhero, is there. He's giving a talk, I think, and chairing at least one session. He asked a question today on Software Underground:

“If anyone has any thoughts or ideas as to what the regulators should be doing differently now is a good time to speak up :)”

My response

For me it's about raising their aspirations. Collectively, they are sitting on one of the most valuable — or invaluable — datasets in the world, comparable to Hubble, or the LHC. Better yet, the data are (in most cases) already open and they actually want to share it. And the community (us) is better tooled than ever, and perhaps also more motivated, to get cracking. So the possibility is there to see a revolution in subsurface science and exploration (in the broadest sense of the word) and my challenge to them is:

Can they now create the conditions for this revolution in earth science?

Some things I think they can do right now:

  • Properly fund the development of an open data platform. I'll expand on this topic below.
  • Don't get too twisted off on formats (go primitive), platforms (pick one), licenses (go generic), and other busy work that committees love to fret over. Articulate some principles (e.g. public first, open source, small footprint, no lock-in, componentize, no single provider, let-users-choose, or what have you), and stay agile. 
  • Lobby NOCs and IOCs hard to embrace integrated and high-quality open data as an advantage that society, as well as industry, can share in. It's an important piece in the challenge we face to modernize the industry. Not so that it can survive for survival's sake, but so that it can serve society for as long as it's needed. 
  • Get involved in the community: open up their processes and collaborate a lot more with the technical societies — like show up and talk about their programs. (How did I not hear about the CDA's unstructured data challenge — a subject I'm very much into — till it was over? How many other potential participants just didn't know about it?)

An open data platform

The key piece here is the open data platform. Here are the features I'd like to see of such a platform:

  • Optimized for users, not the data provider, hosting provider, or system administrator.
  • Clear rights: well-known, documented, obvious, clearly expressed open licenses for re-use.
  • Meaningful levels of access that are free of charge for most users and most use cases.
  • Access for humans (a nice mappy web interface) with no awkward or slow registration processes.
  • Access for machines (a nice API, perhaps even a couple of libraries expressing it).
  • Tools for query, discovery, and retrieval; ideally with user feedback paths ('more like this, less like that').
  • Ways to report, or even fix, problems in the data. This relieves you of "the data's not ready" procrastination.
  • Good documentation of all of this, ideally in a wiki or something that people can improve.
  • Support for a community of users and developers that want to do things with the data.

Building this platform is not trivial. There is massive file storage, database back end, web front end, licensing, and so on. Then there's the community of developers and users to engage and support. It will take years, and never be finished. It sounds hard... but people are doing it. Prototypes for seismic data exist already, and there are countless models in other verticals (just check out the Registry of Research Data Repositories, or look at the list on PLOS). 

The contract to build data infrostructure is often awarded to the likes of Schlumberger, Halliburton or CGG. In theory, these companies have the engineering depth to pull them off (though this too is debatable, especially in today's web-first, native-never world). But they completely lack the culture required: there's no corporate understanding of what 'open' means. So the model is broken in subtle but fatal ways and the whole experiment fails. 

I'm excited to hear what comes out of this conference. If you're there, please tell!

GeoConvention highlights

/

We were in Calgary last week at the Canada GeoConvention 2017. The quality of the talks seemed more variable than usual but, as usual, there were some gems in there too. Here are our highlights from the technical talks...

Filling in gaps

Mauricio Sacchi (University of Alberta) outlined a new reconstruction method for vector field data. In other words, filling in gaps in multi-compononent seismic records. I've got a soft spot for Mauricio's relaxed speaking style and the simplicity with which he presents linear algebra, but there are two other reasons that make this talk worthy of a shout out:

  1. He didn't just show equations in his talk, he used pseudocode to show the algorithm.
  2. He linked to his lab's seismic processing toolkit, SeismicJulia, on GitHub.

I am sure he'd be the first to admit that it is early days for for this library and it is very much under construction. But what isn't? All the more reason to showcase it openly. We all need a lot more of that.

Learning about errors

Anton Birukov (University of Calgary & graduate intern at Nexen) gave a great talk in the induced seismicity session. It was a lovely mashing-together of three of our favourite topics: seismology, machine-learning, and uncertainty. Anton is researching how to improve microseismic and earthquake event detection by framing it as a machine-learning classification problem. He's using Monte Carlo methods to compute myriad synthetic seismic events by making small velocity variations, and then using those synthetic events to teach a model how to be more accurate about locating earthquakes.

The bright lights of geothermal energy
Matt Hall

Two interesting sessions clashed on Wednesday afternoon. I started off in the Value of Geophysics panel discussion, but left after James Lamb's report from the mysterious Chief Geophysicists' Forum. I had long wondered what went on in that secretive organization; it turns out they mostly worry about how to make important people like your CEO think geophysics is awesome. But the large room was a little dark, and — in keeping with the conference in general — so was the mood.

Feeling a little down, I went along to the Diversification of the Energy Industry session instead. The contrast was abrupt and profound. The bright room was totally packed with a conspicuously young audience numbering well over 100. The mood was hopeful, exuberant even. People were laughing, but not wistfully or ironically. I think I saw a rainbow over the stage.

If you missed this uplifting session but are interested in contributing to Canada's geothermal energy scene, which will certainly need geoscientists and reservoir engineers if it's going to get anywhere, there are plenty of ways to find out more or get involved. Start at cangea.ca and follow your nose.

We'll be writing more about the geothermal scene — and some of the other themes in this post — so stay tuned.

Running away from easy

/

Matt and I are in Calgary at the 2017 GeoConvention. Instead of writing about highlights from Day 1, I wanted to pick on one awesome thing I saw. Throughout the convention, there is a air of sadness, of nostalgia, of struggle. But I detect a divide among us. There are people who are waiting for things to return to how they were, when life was easy. Others are exploring how to be a part of the change, instead of a victim of it. Things are no longer easy, but easy is boring. 

Want to start an oil and gas company? What resources are you going to need? Computers, pricey software applications, data. Purchase all of this stuff as a one-time capital expense, build a team, get an office lease, buy desks and a Keurig. Then if all goes well, 18 months later you'll have a slide deck outlining a play that you could pitch to investors. 

Imagine getting started without laying down a huge amount of capital for all those things. What if you could rent a desk at a co-working space, access the suite of software tools that you're used to, and use their Keurig. The computer infrastructure and software is managed and maintained by an IT service company so you don't have to worry about it. 

Yesterday at the Calgary Geoconvention I heard all about ReSourceYYC, a co-working space catering to oil and gas professionals, introduced ResourceNET, a subscription-based cloud workstation environment for freelancers, consultants, startups, and the newly and not-so-newly underemployed community of subsurface professionals.

In making this offering, ReSourceYYC has partnered up with a number of software companies: Entero, Seisware, Surfer, ValNav, geoLOGIC, and Divestco, to name a few. The limitations and restrictions around this environment, if any, weren't totally clear. I wondered: Could I append or swap my own tools with this stack? Can I access this environment from anywhere?

It could be awesome. I think it could serve just as many freelancers and consultants as "oil and gas startups". It seems a bit too early to say, but I reckon there are literally thousands of geoscientists and engineers in Calgary that'd be all over this.

I think it's interesting and important and I hope they get it right.
