January linkfest

Time for the quarterly linkfest! Got stories for next time? Contact us.

BP's new supercomputer, reportedly capable of about 2.2 petaflops, is about as fast as Total's Pangea machine in Paris, which booted up almost a year ago. These machines are pretty amazing — Pangea has over 110,000 cores, and 442 terabytes of memory — but BP claims to have bested that with 1 petabyte of RAM. Remarkable. 

Leo Uieda's open-source modeling tool Fatiando a Terra got an upgrade recently and hit version 0.2. Here's Leo himself demonstrating a forward seismic model:

I'm a geoscientst, get me out of here is a fun-sounding new educational program from the European Geosciences Union, which has recently been the very model of a progressive technical society (along with the AGU is another great example). It's based on the British outreach program, I'm a scientist, get me out of here, and if you're an EGU member (or want to be), I think you should go for it! The deadline: 17 March, St Patrick's Day.

Darren Wilkinson writes a great blog about some of the geekier aspects of geoscience. You should add it to your reader (I'm using The Old Reader to keep up with blogs since Google Reader was marched out of the building). He wrote recently about this cool tool — an iPad controller for desktop apps. I have yet to try it, but it seems a good fit for tools like ArcGIS, Adobe Illustrator.

Speaking of big software, check out Joe Kington's Python library for GeoProbe volumes — I wish I'd had this a few years ago. Brilliant.

And speaking of cool tools, check out this great new book by technology commentator and philosopher Kevin Kelly. Self-published and crowd-sourced... and drawn from his blog, which you can obviously read online if you don't like paper. 

If you're in Atlantic Canada, and coming to the Colloquium next weekend, you might like to know about the wikithon on Sunday 9 February. We'll be looking for articles relevant to geoscientists in Atlantic Canada to improve. Tim Sherry offers some inspiration. I would tell you about Evan's geocomputing course too... but it's sold out.

Heard about any cool geostuff lately? Let us know in the comments. 

52 Things is out!

The new book is out! You can now order it from Amazon.com, Amazon.co.uk, Amazon in Europe, and it will be available soon from Amazon.ca and various other online bookstores.

What's it about? I sent Andrew Miall some chapters at the proof stage; here's what he said:

Geology is all about rocks, and rocks are all about detail and field context, and about actually being out there at that critical outcrop, right THERE, that proves our point. The new book 52 Things You Should Know About Geology is full of practical tips, commentary, and advice from real geologists who have been there and know what the science is all about.

Amazing authors

A massive thank you to my 41 amazing co-authors...

Eight of these people also wrote in 52 Things You Should Know About Geophysics; the other 34 are new to this project. Between them, this crowd has over 850 years of experience in geoscience (more remarkably, just two of them account for 100 years!). Half of the authors are primarily active in North America; others are in the UK, Germany, Indonesia, India, the Netherlands, and Norway. Ten are engaged in academia, four of them as students. The diversity is wonderful as far as it goes, but the group is overwhelmingly composed of white men; it's clear we still have work to do there. 

We have the globe mostly covered in the essays themselves too. Regrettably, we have gaping holes over South America and most of Africa. We will endeavour to fix this in future books. This map shows page numbers...

Giving back

Academic publishing is a fairly marginal business, because the volumes are so small. Furthermore, we are committed to offering books at consumer, not academic, prices. The 42 authors have shown remarkable generosity of time and spirit in drafting these essays for the community at large. If you enjoy their work, I'm certain they'd love to hear about it.

In part to recognize their efforts, and to give something back to the community that supports these projects (that's you!), we approached the AAPG Foundation and offered to donate $2 from every sale to the charity. They were thrilled about this — and we look forward to helping them bring geoscience to more young people.

These books are all about sharing — sharing knowledge and sharing stories. These are the things that make our profession the dynamic, sociable science that it is. If you would like to order 10 or more copies for your friends, students, or employees, do get in touch and we will save you some money.

52 Things... About Geology

Welcome to the new book from Agile Libre! The newest, friendliest, awesomest book about petroleum geoscience. 

The book will be out later in November, pending review of the proof, but you can pre-order it now from Amazon.com at their crazy offer price of only $13.54. When it comes out, the book will hit Amazon.ca, Amazon.co.uk, and other online booksellers.

63 weeks to mature

It's truly a privilege to publish these essays. When an author hands over a manuscript, they are trusting the publisher and editors to do justice not just to the words, but to the thoughts inside. And since it's impossible to pay dozens of authors, they did it all for nothing. To recognize their contributions to the community, we're donating $2 from every book sale to the AAPG Foundation. Perhaps the students that benefit from the Foundation will go on to share what they know. 

This book took a little stamina, compared to 52 Things... Geophysics. We started inviting authors on 1 July 2012, and it took 442 days to get all the essays. As before, the first one came almost immediately; this time it was from George Pemberton, maintaining the tradition of amazing people being great champions for these projects. Indeed, Tony Doré — another star contributor — was a big reason the book got finished.

What's inside?

To whet your appetite, here are the first few chapters from the table of contents:

  • Advice for a prospective geologist — Mark Myers, 14th Director of the USGS
  • As easy as 1D, 2D, 3D — Nicholas Holgate, Aruna Mannie, and Chris Jackson
  • Computational geology — Mark Dahl, exploration geologist at ConocoPhillips
  • Coping with uncertainty — Duncan Irving at TeraData
  • Geochemical alchemy — Richard Hardman, exploration legend
  • Geological inversion — Evan Bianco of Agile
  • Get a helicopter not a hammer — Alex Cullum of Statoil

Even this short list samples some of the breadth of topics, and the range of experience of the contributors. Nichlas and Aruna are PhD students of Chris Jackson at Imperial College London, and Richard Hardman is a legend on the UK exploration scene, with over 50 years of experience. Between them, the 42 authors have notched up over 850 career-years — the book is a small window into this epic span of geological thinking.

We're checking the proofs right now. The book should be out in about 2 weeks, just in time for St Barbara's day!

Pre-order now from Amazon.com 
Save more than 25% off the cover price!

It's $13.54 today, but Amazon sets the final price... I don't know how long the offer will last. 

October linkfest

From Hart (2013). ©SEG/AAPGIt's the Hallowe'en linkfest! Just the good bits from our radar...

If you're a member of SEG or AAPG, you can't have missed their new joint-venture journal, Interpretation. Issue 2 just came out. My favourite article so far has been Bruce Hart's Whither seismic stratigraphy in Issue 1. It included these excellent little forward models from an earlier paper of his — it's so important for interpreter's to think in this space where geological architecture and geophysical imaging overlap. 

Muon tomography is in the news again, this time in relation to monitoring CCS repositories (last time it was volcanos). Jon Gluyas, author of the textbook Petroleum Geoscience, is the investgator at Durham in the UK (my alma mater). I do love the concept — imaging the subsurface with cosmic rays — but I'm only just getting to grips with sound waves.

If you read this blog regularly, you probably have some geeky tendencies. We've linked to a couple of these blogs before, but they're must-read for anyone into technology and geoscience, with lots of code and workflow examples: 

Continuing the geeky theme, we've been getting more and more into building things recently. Check out our fiddling in GitHub (a code repository) — an easy way in is code.agilegeoscience.com. Watch this space!

Speaking of fiddling with code, you already know about the hackathon we hosted in Houston last month. But there's talk of repeating the fun at the AAPG Annual Convention, also in Houston, in April next year. Brian Romans has started a list of potential projects around digital stratigraphy — please leave a comment there or here to add to it. Where's the gap in your workflow?

A few more quick hits:

What we built at the weekend

10 days ago we wrapped up the Geophysics Hackathon in Houston. I wrote a bit about it right after the event, but now I've gathered the evidence and can share more of the awesome. First of all — what did everyone build in the 2 days? 

Team 1: Velocity modelling in iOS

Essau Worthy-Blackwell (Southwestern Energy), Jacob Foshee (independent iOS dev), Evan Bianco (Agile), and Ben Bougher (independent, mostly helping Agile) built 2 tools exploring velocity modelling and depth conversion. One was a desktop tool (in Python), the other was an iOS app — watch this.

Team 2: LAS soup demux

Joe Jennings (Colorado School of Mines), Mike Stone (Lukoil), and Karl Schleicher (University of Texas at Austin) built a tool in Python for coping with messy data. Karl is a champion of open data, and needs a tool for quickly exploring large repositories. You can see their progress in the code in GitHub — feel free to help them out!

Team 3: A 1D forward model

Duncan Child (Spectraseis) joined Chris Chalcraft, Paul Garossino, and James Alison from OpenGeoSolutions to help out with his pumped up Java and JSON wrangling skills. Greg Partyka even popped in to help. Here is Blockfilter in GitHub.

Everyone's a winner

As well as being a fun way to get to know people, and create something new together, the event was a (very low key) contest. We had some experienced and perceptive judges to pick some winners and decide how the exactly 3 prizes would be distributed among the exactly 3 teams:

  • Team 3 were awarded with some Raspberry Pi starter kits, to recognize their solid idea, well-constructed code, and respect for work-life balance (hey, it was the weekend!). It was fun peeking over their shoulders occasionally.

  • Team 2 had the most commercially viable product, and as such went away with 2 books: The Lean Startup by Eric Ries, and Business Model Generation by Alex Osterwalder. Thanks to sponsor SURGE Accelerator, the team also won the chance to talk to a business mentor about their ideas.

  • Team 1 delivered the shiniest product at the end of the weekend, with the iOS app and a desktop clone. They each won one of Google's latest Nexus 7 tablets, to continue with their app-building skills.

What will you build?

Thanks again to the daredevils who showed up, the judges — especially Maitri Erwin, who helped out in lots of ways all weekend — and of course the sponsors: OpenGeoSolutions, Enthought, and dGB Earth Sciences. If you missed the event, dear reader, I hope you'll come along next time to share ideas, test workflows, and build new things.

Standards, streamers, and Sherlock

Yesterday afternoon at the SEG Annual Meeting I spent some time with Jill Lewis from Troika and Rune Hagelund, a consultant. They have both served on the SEG Standards Committee, helping define the SEG-D and SEG-Y standards for field data and processed data respectively. The SEG standards are — in my experience — almost laughably badly implemented by most purveyors of data. Why is this? Is the standard too inflexible? Are the field definitions unclear? The confusion can lead to real problems: I know I've inadvertently loaded a seismic survey back to front. If you feel passionately about it, the committee is always looking for feedback.

Land streamerI wandered past a poster yesterday morning about land streamers. The last I'd seen of this idea — dragging a train of geophones behind a truck — was a U of C test at Priddis, Alberta, by Gabriella Suarez and Rob Stewart. I haven't been paying much attention, but this was the first commercial implementation I'd seen – a shallow acquifer study in Sweden, reported by Boiero et al. The truck has the minivibe source right behind it, and the streamer after that. Quicker than juggies!

I don't know if this is a function of my recent outlook on conferences, but this was the first conference I've been to where all of the best things have been off-site. Perhaps the best part of the week was last night — a 3-hour geek-fest with Evan, Ben Bougher, Sam Kaplan, and Bernal Manzanilla. The conversation covered compressive sensing, stochastic resonance, acoustic lenses, and the General Inverse-Problemness of All Things.

As I mentioned last week, I hung out every day in the press room, waiting for wiki-curious visitors. We didn't have many drop-ins (okay, four), but I had some great chats with SEG staff, my friend Mike Stone, and a couple of other enthusiasts. I also started some fun projects to move some quality content into SEG Wiki. If you're at all interested in seeing a vibrant, community-driven space for geophysical knowledge, do get involved.

I bought some books in the Book Mart yesterday: Planning Land 3D Seismic Surveys by Andreas Cordsen et al., 3D Seismic Survey Design by Gijs Vermeer, and Fundamentals of Geophysical Interpretation by Larry Lines and Rachel Newrick. We're increasingly interested in modeling, and acquisition is where it all begins; Lines and Newrick was mostly just a gap on the shelf, but it also covers some topics I have little familiarity with, such as electromagnetics. Jennifer Cobb, SEG publications manager, showed me the intriguing new monograph by geophysical legend Enders Robinson and TLE Editor Dean Clark — I can't quite remember the title but it had something to do with Sherlock Holmes and Albert Einstein — a story about scientific investigation and geophysics. Looking forward to picking that up.

That's it for me this year; I'm writing this on the flight home. Evan is staying for the workshops and will report on those. As usual, I'm leaving with a lot of things to follow up on over the next weeks and months. I'm also trying to sift my feelings about the Annual Meeting, and especially the Exhibition. So many people, so much time, so much marketing...

July linkfest

It's another linkfest! All the good stuff from our newsfeed over the last few weeks.

We mentioned the $99 supercomputer in April. The Adapteva Parellella is a bit like a Raspberry Pi, but with the added benefit of a 16- or 64-core coprocessor. The machines are now shipping, and a version is available for pre-order.

In April we also mentioned the University of Queensland's long-running pitch drop experiment. But on 18 July a drop fell from another similar experiment, but which has even slower drops...

A gem from history:

In the British Islands alone, twice as much oil as the navy used last year could be produced from shale. — Winston Churchill, July 1913.

This surprising quote was doing the rounds last week (I saw it on oilit.com), but of course Churchill was not fortelling hydraulic fracturing and the shale gas boom; he was talking about shale oil. But it's still Quite Interesting.

Chris Liner's blog is more than quite interesting — and the last two posts have been especially excellent. The first is a great tutorial video describing a semi-automatic rock volume estimation workflow. You can get grain size and shape data from the same tool (tip: FIJI is the same but slightly awesomer). And the most recent post is about a field school in the Pyrenees, a place I love, and contains some awesome annotated field photos from an iPhone app called Theodolite.

Regular readers will already know about the geophysics hackathon we're organizing in Houston in September, timed perfectly as a pre-SEG brain workout. You don't need to be a coder to get involved — if you're excited by the idea of creating new apps for nerds like you, then you're in! Sign up at hackathon.io.

EAGE 2013 in a nutshell

I left London last night for Cambridge. On the way, I had a chance to reflect on the conference. The positive, friendly vibe, and the extremely well-run venue. Wi-Fi everywhere, espresso machines and baristas keeping me happy and caffeinated.

Knowledge for sale

I saw no explicit mention of knowledge sharing per se, but many companies are talking about commoditizing or productizing knowledge in some way. Perhaps the most noteworthy was an update from Martyn Millwood Hargrave at Ikon's booth. In addition to the usual multi-client reports, PowerPoint files, or poorly architected database, I think service companies are still struggling to find a model where expertise and insight can be included as a service, or at least a value-add. It's definitely on the radar, but I don't think anyone has it figured out just yet.

Better than swag

Yesterday I pondered the unremarkability of carrot-and-ginger juice and Formula One pit crews. Paradigm at least brought technology to the party. Forget Google Glass, here's some augmented geoscience reality:

Trends good and bad

This notion of 3D seismic vizualization and interpretation is finally coming to gathers. The message: if you are not going pre-stack, you are missing out. Pre-stack panels are being boasted in software demos by the likes of DUG, Headwave, Transform, and more. Seems like this trend has been moving in slow motion for about a decade.

Another bandwagon is modeling while you interpret. I see this as an unfeasible and potentially dangerous claim, but some technologies companies are creating tools and workflows to fast-track the seismic interpretation to geologic model building workflows. Such efficiencies may have a market, but may push hasty solutions down the value chain. 

What do you think? What trends do you detect in the subsurface technology space? 

Where have all the geologists gone?

ExCel LondonFresh off the plane from my vacation in Europe, I spent today exploring the Exhibition at ExCel London, at the 2013 EAGE convention. It's a massive venue, and I spent the entire day there having conversations. I didn't look upon a single PowerPoint slide all day, and it was awesome. 

Seismic domination

This is my first time at the EAGE conference, and I was expecting to see an fairly equal spread of geoscientists and engineers. I was wrong. The exhibition hall at least, is dominated by seismic acquisition and processing companies. Which suggests one thing. There is big business in seismic methods — manufacturing equipment, designing and acquiring surveys, and processing all that data.

Additionally, I counted 17 operating companies out on display. Recruiting and networking hoopla at its finest. In contrast, I don't think I saw one operator on the exhibition floor one month ago at the Calgary GeoConvention.  

Apparently, geophysics is hot. But where have all the geologists gone? Are they lurking in the shadows? Based on the technology represented at the exhibition, are we at the risk of homogenizing the industry and all calling ourselves geophysicists one day?

EAGE ExhibitionEven though the diversity of disciplines appears to be lacking, marketing creativity certainly is not. Today, I listened to a string quartet perform at one booth, while sipping on a carrot-and-ginger juice freshly squeezed at another. Moments later, I struggled through a hard-to-hear conversation because the noise from a Formula One pit crew demonstration was deafening. It is both amazing and disturbing the expense companies will rack up to try to be remarkable. But such remarks of the fleeting kind. It fades as quickly as the song, drink, or tire-change is over.

And being a spectator of it all, I am reminded that the remarkability I am after is of the more enduring kind.
