New open data and a competition

/

First, a quick announcement. EMC, the data storage and cloud computing company, has stepped up to sponsor the Subsurface Hackathon in Vienna in a few weeks. Their generous help will ensure a fun event with some awesome prizes — so get signed up and start planning your project!

New open data

A correspondent got in touch last week about an exciting new open seismic dataset. In the late summer and early autumn of 2015, the WesternGeco-acquired a large new 2D seismic survey in the Rockall Basin and the Mid North Sea High for the UK Government. The survey cost about £20 million and consists of 20,000 km of new broadband PreSTM data. At the end of March, the dataset will be released to the public for free download, along with about 20,000 km of legacy 2D data, 40,000 km of new gravity and magnetic data, and wells.

If you are interested in downloading the data, the government is asking that you fill out this form — it will help them figure out what to make available, and how much infrastructure to provision. Excitingly, they are asking about angle stacks, PSTM gathers, not just the full stack. It sounds like being an important resource for our community.

They are even asking about interest in the field data — all 60TB of it. There will almost certainly be a fee associated with the larger datasets, by the way. I asked about this and it sounds like it will likely be on the order of several thousand pounds to handle the full SEGD data, because of course it will be on physical media. But the government is open to suggestions if the geophysical community would like to find another way to distribute the data — do let me know if you'd like to talk about this.

New seed funding

Along with the data package, the government has announced an exciting new competition for 'seed funding':

The £500,000 competition has been designed to encourage geoscientists and engineers to develop innovative interpretations and products potentially using [this new open data]...

The motivation for the competition is clear:

It is hoped the competition will not only significantly increase the understanding of these frontier areas in respect of the 29th Seaward Licensing Round later in the year, but also retain talent in the oil and gas community which has been affected by the oil and gas industry downturn.

The parameters of the competition are spelled out in the Word document on this tender notice. It sounds like almost anything goes: data analysis, product development, even exploration activity. So get creative — and pitch the coolest thing you can think of!

You'll have to get cracking though, because applications to take part must be in by 1 April. If selected, the project must be delivered on 11 November.

Monday highlights from SEG

/

Ben and I are in New Orleans at the 2015 SEG Annual Meeting, a fittingly subdued affair, given the industry turmoil recently. Lots of people are looking for work, others are thankful to have it.

We ran our annual Geophysics Hackathon over the weekend; I'll write more about that later this week. In a nutshell: despite a low-ish turnout, we had 6 great projects, all of them quite different from anything we've seen before. Once again, Colorado School of Mines dominated.

Beautiful maps

One of the most effective ways to make a tight scientific argument is to imagine trying to convince the most skeptical person you know that your method works. When it comes to seismic attribute analysis, I am that skeptical person.

Some of the nicest images I saw today were in the 'Attributes for Stratigraphic Analysis' session, chaired by Rupert Cole and Yuefeng Sun. For example, Tao Zhao, one of Kurt Marfurt's students, showed some beautiful images from the Waka 3D offshore New Zealand (Zhao & Marfurt). He used 2D colourmaps to co-render two attributes together, along with semblance mapped to opacity on a black layer, and were very nice to look at. However I was left wondering, and not for the first time, how we can do a better job calibrating those maps to geology. We (the interpretation community) need to stop side-stepping that issue; it's central to our credibility. Even if you have no wells, as in this study, you can still use forward models, analogs, or at least interpretation by a sedimentologist, preferably two.

Pavel Jilinski at GeoTeric gave a nice talk (Calazans Muniz et al.) about applying some of these sort of fancy displays to a large 3D dataset in Brazil, in a collaboration with Petrobras. The RGB displays of spectral attributes were as expected, but I had not seen their cyan-magenta-yellow (CMY) discontinuity displays before. They map dip to the yellow channel, similarity to the magenta channel, and 'tensor discontinuity' to the cyan channel. No, I don't know what that means either, but the displays were pretty cool.

Publications news

This evening we enjoyed the Editor's Dinner (I coordinate a TLE column and review for Geophysics and Interpretation, so it's totally legit). Good things are coming to the publication world: adopted Canadian Mauricio Sacchi is now Editor-in-Chief, there are no more page charges for colour in Geophysics (up to 10 pages), and watch out for video abstracts next year. Also, Chris Liner mentioned that Interpretation gets 18% of its submissions from oil companies, compared to only 5% for Geophysics. And I heard, but haven't verified, that downturns result in more papers. So at least our journals are healthy. (You do read them, right?)

That's it for today (well, yesterday). More tomorrow!

The perfect storm

/

Since starting Agile late in 2010, I have never not been busy. Like everyone else... there's always a lot going on. But March was unusual. Spinning plates started wobbling. One or three fell. One of those that fell was the blog. (Why is it always your favourite plate that smashes?)

But I'm back, feeling somewhat refreshed after my accidental quadrennial sabbatical and large amounts of Easter chocolate. And I thought a cathartic way to return might be to share with you what I've been up to.

Writing code for other people

We've always written code to support our consulting practice. We've written seismic facies algorithms, document transformation routines (for AAPG Wiki), seismic acquisition tools, and dozens of other things besides. But until January we'd never been contracted to build software as an end in itself.

Unfortunately for my sanity, the projects had to be finished by the end of March. The usual end-of-project crunch came along, as we tried to add features, fix bugs, remove cruft, and compile documentation without breaking anything. And we just about survived it, thanks to a lot of help from long-time Agile contributor, Ben Bougher. One of the products was striplog, a new Python library for manipulating well data, especially irregularly sampled, interval-based, qualitative data like cuttings descriptions. With some care and feeding, I think it might be really useful one day.

The HUB is moving

Alongside the fun with geoscience, we're in the midst of a fairly huge renovation. As you may know, I co-founded The HUB South Shore in my town in 2013. It's where I do my Agile work, day-to-day. It's been growing steadily and last year we ran out of space to accept new members. So we're moving down to the Main Street in Mahone Bay, right under the town's only pub. It's a great space, but it turns out that painting a 200 m² warehouse takes absolutely ages. Luckily, painting is easy for geologists, since it's basically just a lot of arm-waving. Anyway, that's where I'm spending my free time these days. [Pics.]

Shovelling snow

What my house has looked like for the last 8 weeks.

What my house has looked like for the last 8 weeks.

Seriously, it just will. Not. Stop. It's snowing now, for goodness sake. I'm pretty sure we have glaciers.

What does this have to do with work? Well, we're not talking about Calgary-style pixie dust here. We ain't nipping out with the shovel for a few minutes of peaceful exercise. We're talking about 90 minutes of the hardest workout you've ever endured, pointlessly pushing wet snow around because you ran out of places to put it three weeks ago. At the end, when you've finished and/or given up, Jack Frost tosses a silver coin to see if your reward will be a hot shower and a course of physiotherapy, or sudden cardiac arrest and a ride in the air ambulance.

Events

There is lots of good techno-geophysics to look forward to. We're running the Geoscience Hackathon in Calgary at the beginning of May. You can sign up here... If you're not sure, sign up anyway: I guarantee you'll have fun. There's a bootcamp too, if you're just starting out or want some tips for hacking geophysics. Thank you to our awesome sponsors:

There's also the geophysics mini-symposium at SciPy in Austin in July (deadline approaching!). That should be fun. And I'm hoping the hackathon right before SEG in New Orleans will be even more epic than last year's event. The theme: Games.

Evan is out there somewhere

Normally when things at Agile World Headquarters get crazy, we can adapt and cope. But it wasn't so easy this time: Evan is on leave and in the middle of an epic world tour with his wife Tara. I don't actually know where he is right now. He was in Bali a couple of weeks ago... If you see him say Hi!

As I restart the engines on All The Things, I want to thank anyone who's been waiting for an email reply, or — in the case of the 52 Things... Rock Physics authors — a book, for their patience. Sometimes it all hits at once.

Onwards and upwards!

February linkfest

/

The linkfest is back! All the best bits from the news feed. Tips? Get in touch.

The latest QGIS — the free and open-source GIS we use — dropped last week. QGIS v2.8 'Wien' has lots of new features like expressions in property fields, better legends, and colour palettes.

On the subject of new open-source software, I've mentioned Wayne Mogg's OpendTect plug-ins before. This time he's outdone himself, with an epic new plug-in providing an easy way to write OpendTect attributes in Python. This means we can write seismic attribute algorithms in Python, using OpendTect for I/O,project management, visualization, and interpretation. 

It's not open source, but Google Earth Pro is now free! The free version was pretty great, but Pro has a few nice features, like better measuring tools, higher resolution screen-grabs, movies, and ESRI shapefile import. Great for scoping field areas.

Speaking of fieldwork, is this the most amazing outcrop you've ever seen? Those are house-sized blocks floating around in a mass-transport deposit. If you want to know more, you're in luck, because Zane Jobe blogged about it recently.  (You do follow his blog, right?)

By the way, if sedimentology is your thing, for some laboratory eye-candy, follow SedimentExp on Twitter. (Zane's on Twitter too!)

If you like to look after your figures, Rougier et al. recently offered 10 simple rules for making them better. Not only is the article open access (more amazing: it's public domain), the authors provide Python code for all their figures. Inspiring.

Open, even interactive, code will — it's clear — be de rigueur before the decade is out. Even Nature is at it. (Well, I shouldn't say 'even', because Nature is a progressive publishing hose, at the same time as being part of 'the establishment'.) Take a few minutes to play with it... it's pretty cool. We have published lots of static notebooks, as has SEG; interactivity is coming!

A question came up recently on the Earth Science Stack Exchange that made me stop and think: why do geophysicists use \(V_\mathrm{P}/V_\mathrm{S}\) ratio, and not \(V_\mathrm{S}/V_\mathrm{P}\) ratio, which is naturally bounded. (Or is it? Are there any materials for which \(V_\mathrm{S} > V_\mathrm{P}\)?) I think it's tradition, but maybe you have a better answer?

On the subject of geophysics, I think this is the best paper title I've seen for a while: A current look at geophysical detection of illicit tunnels (Steve Sloan in The Leading Edge, February 2015). Rather topical just now too.

At the SEG Annual Meeting in Denver, I recorded an interview with SEG's Isaac Farley about wikis and knowledge sharing...

OK, well if this is just going to turn into blatant self-promotion, I might as well ask you to check out Pick This, now with over 600 interpretations! Please be patient with it, we have a lot of optimization to do...

What does Agile actually do?

/
For the forgetful and/or the nostalgic, here's a reminder of what the old site looked like. If there's a particular feature you miss, please let us know!

For the forgetful and/or the nostalgic, here's a reminder of what the old site looked like. If there's a particular feature you miss, please let us know!

There's one question almost everybody asks us: "What do you guys actually do?". The more brazen get straight to the point: "How do you guys make money?". One way to answer this question, without making people wait till they meet us, is with the website. And our website has always been quite... bloggy. It's easy to see how we don't make money, less obvious how we do.

New website

After 4 years with the same design, we've given the site a new look. Four years is half a lifetime in web years, so we now have lots of upgraded features, like mobile responsiveness, integrated commerce, and lots of dynamic content. We can also make it a bit easier to see what people hire us for, and to hire us yourself. 

Here's a quick overview of some of the new content:

  • Services — things we do for money.
  • Courses — boost your skills as a scientist and communicator.
  • Products — things we make... for money, or for fun, or because they have to be done.
  • Shop — where you can buy boxes of books, and maybe more one day. 
  • Projects — some of the bigger things we're into right now, like Modelr and SubSurfWiki.

I still find it hard to describe what we do, and I kind of like it that way. We're not easy to pigeonhole. We're fortunate not only to have always had enough work, but also to work with some of the smartest and most energetic people in our industry. But I hope our new site goes some way to making it easier to find out how we might be able to help you and your organization be a bit more awesome. That's what we're here for. 

Some geeky footnotes

For anyone who's interested, the site is powered by Squarespace 7. We were previously on Squarespace 5. There's a lot of upside to a package deal like Squarespace, but of course you lose some flexibility. I might have thought about moving to another platform, perhaps WordPress and its open source goodness, but in the end the ease of transferring our 400+ blog posts was the deciding factor. 

For those of you using a news reader like The Old Reader to read our blog, please note that the old 'journal' feed URL no longer works — please update it to http://www.agilegeoscience.com/blog?format=RSS. The Feedburner feed is still active, at least for now.

2014 retrospective

/

At this time of year, we look back at the best of the blog — what were the most read, the most contentious, the most informative posts of the year? If you only stop by once every 12 months, this is the post for you!

Your favourites

Let's turn to the data first. Which posts got the most hits this year? Older posts have a time advantage of course, but here are the most popular new posts, starting with the SEG-Y double-bill:

It's hard to say exactly how much attention a given post gets, because they sit on the front page of the site for a couple of weeks. Overall we got about 150 000 pageviews this year, and I think Well tie workflow — the most-read old post on the site this year — might have been read (okay, looked at) 5000 or so times.

I do love how some of our posts keep on giving: none of the top posts this year topped this year's readership of some golden oldies: Well tie workflow (written in April 2013), Six books about seismic interpretation (March 2013), k is for wavenumber (May 2012), Interpreting spectral gamma-ray logs (February 2013), or Polarity cartoons (April 2012).

What got people talking

When it all goes quiet on the comments, I worry that we're not provocative enough. But some posts provoke a good deal of chat, and always bring more clarity and depth to the issue. Don't miss the comments in Lusi's 8th birthday...

Our favourites

We have our favourites too. Perhaps because a lot of work went into them (like Evan's posts about programming), or because they felt like important things to say (as in the 'two sides' post), or because they feel like part of a bigger idea.

Where is everybody?

We don't collect detailed demographic data, but it's fun to see how people are reading, and roughly where they are. One surprise: the number of mobile readers did not rise this year — it's still about 15%. The top 10 cities were

Last thing

Thank You for reading! Seriously: we want to be a useful and interesting part of our community, so every glance at our posts, every comment, and every share, help us figure out how to be more useful and more interesting. We aim to get better still next year, with more tips and tricks, more code, more rants, and more conference reports — we look forward to sharing everything Agile with you in 2015.

If this week is Christmas for you, then enjoy the season. All the best for the new year!

The new open geophysics tools

/

The hackathon in Denver was more than 6 weeks ago. I kept thinking, "Oh, I must post a review of what went down" (beyond the quick wrap-up I did at the time), but while I'm a firm believer in procrastination six weeks seems unreasonable... Maybe it's taken this long to scrub down to the lasting lessons. Before those, I want to tell you who the teams were, what they did, and where you can find their (100% open source!) stuff. Enjoy!

Geophys Wiz

Andrew Pethick, Josh Poirier, Colton Kohnke, Katerina Gonzales, and Elijah Thomas — GitHub repo

This team had no trouble coming up with ideas — perhaps a reflection of their composition, which was more heterogeneous than the other teams. Josh is at NEOS, the consulting and software firm, and Andrew is a postdoc at Curtin in Perth, Australia, while the other 3 are students at Mines. The team eventually settled on building MT Black Box, a magnetotellurics modeling web application. 

Last thing: Don't miss Andrew Pethick's write-up of the event. 

Seemingly Concerned Neighbours

Elias Arias, Brent Putman, Thomas Rapstine, and Gabriel Martinez — Github repo

These four young geophysicists from the Colorado School of Mines impressed everyone with their work ethic. Their tight-knit team came in with a plan, and proceeded to scribble up the coolest-looking whiteboard of the weekend. After learning some Android development skills 'earlier this week', they pulled together a great little app for forward modeling magnetotelluric responses. 

Hackathon_well_tie_guys.jpg

Well tie guys

Michaël Montouchet, Graham Dawes, Mark Roberts

It was terrific to have pro coders Graham and Michaël with us — they flew from the UK to be with us, thanks to their employer and generous sponsor ffA GeoTeric. They hooked up with Mark, a Denver geophysicist and developer, and hacked on a well-tie web application, rightly identifying a gap in the open source market, so to speak (there is precious little out there for well-based workflows). They may have bitten off more than they could chew in just 2 days, so I hope we can get together with them again to finish it off. Who's up for a European hackathon? 

These two characters from UBC didn't get going till Sunday morning, but in just five hours they built a sweet web app for forward modeling the DC resistivity response of a buried disk. They weren't starting from scratch, because Rowan and others have spent months honing SimPEG, a rich open-source geophysical library, but minds were nonetheless blown.

Key takeaway: interactivity beyond sliders for the win.

Pick This!

Ben Bougher, Jacob Foshee, Evan Bianco, and an immiscible mixture of Chris Chalcraft and me — GitHub repo

Wouldn't you sometimes like to know how other people would interpret the section you're working on? This team, a reprise of the dream team from Houston in 2013, built a simple way to share images and invite others to interpret them. When someone has completed their interpretation, only then do they get to see the ensemble — everyone else's interpretations — in a heatmap. Not only did this team demo live software at pickthis.io, but the audience provided the first crowdsourced picks in real time. 

We'll be blogging more about Pick This soon. We're actively seeking ideas, images, interpreters, and financial support. Keep an eye out.

What I learned at this hackathon

  • Potential fields are an actual thing! OK, kidding, but three out of five teams built potential field modeling tools. I wasn't expecting that, and I think the judges were impressed at the breadth. 
  • 30 hours is easily enough time to build something pretty cool. Heck, 5 hours is enough if you're made of the right stuff. 
  • Students can happily build prototypes alongside professional developers, and even teach them a thing or two. And vice versa. Are hackathons a leveller of playing fields?
  • We need to remove the road blocks to more people enjoying this event. To help with this, next time there will be a 1-day bootcamp before the hackathon.
  • After virtually doubling in size from 2013 to 2014, it's clear that the 2015 Hackathon in New Orleans is going to be awesome! Mark your calendar: 17 and 18 October 2015.

Thank you!

Thank you to the creative, energetic geophysicists that came. It was a privilege to meet and hack with you!

Thank you to the judges who gave up their Sunday teatime to watch the demos and give precious feedback to the teams: Steve Adcock, Jamie Allison, Maitri Erwin, Dennis Cooke, Chris Krohn, Shannon Bjarnason, David Holmes, and Tracy Stark. Amazing people, one and all.

A final Thank You to our sponsors — dGB Earth Sciences, ffA GeoTeric, and OpenGeoSolutions. You guys are totally awesome! Seriously.

Another 52 Things hits the shelves

/

The new book is out today: 52 Things You Should Know About Palaeontology. Having been up for pre-order in the US, it is now shipping. The book will appear in Amazons globally in the next 24 hours or so, perhaps a bit longer for Canada.

I'm very proud of this volume. It shows that 52 Things has legs, and the quality is as high as ever. Euan Clarkson knows a thing or two about fossils and about books, and here's what he thought of it: 

This is sheer delight for the reader, with a great range of short but fascinating articles; serious science but often funny. Altogether brilliant!

Each purchase benefits The Micropalaeontological Society's Educational Trust, a UK charity, for the furthering of postgraduate education in microfossils. You should probably go and buy it now before it runs out. Go on, I'll wait here...

1000 years of fossil obsession

So what's in the book? There's too much variety to describe. Dinosaurs, plants, foraminifera, arthropods — they're all in there. There's a geographical index, as before, and also a chronostratigraphic one. The geography shows some distinct clustering, that partly reflects the emphasis on the science of applied fossil-gazing: biostratigraphy. 

The book has 48 authors, a new record for these collections. It's an honour to work with each of them — their passion, commitment, and professionalism positively shines from the pages. Geologists and fossil nuts alike will recognize many of the names, though some will, I hope, be new to you. As a group, these scientists represent  1000 years of experience!

Amazingly, and completely by chance, it is one year to the day since we announced 52 Things You Should Know About Geology. Sales of that book benefit The AAPG Foundation, so today I am delighted to be sending a cheque for $1280 to them in Tulsa. Thank you to everyone who bought a copy, and of course to the authors of that book for making it happen.

Big imaging, little imaging, and telescopes

/

I caught three lovely talks at the special session yesterday afternoon, Recent Advances and the Road Ahead. Here are my notes...

The neglected workhorse

If you were to count up all the presentations at this convention on seismic migration, only 6% of them are on time migration. Even though it is the workhorse of seismic data processing, it is the most neglected topic in migration. It's old technology, it's a commodity. Who needs to do research on time migration anymore? Sergey does.

Speaking as an academic, Fomel said, "we are used to the idea that most of our ideas are ignored by industry," even though many transformative ideas in the industry can be traced back to academics. He noted that it takes at least 5 years to get traction, and the 5 years are up for his time migration ideas, "and I'm starting to lose hope". Here's five things you probably didn't know about time migration:

  • Time migration does not need travel times.
  • Time migration does not need velocity analysis.
  • Single offsets can be used to determine velocities.
  • Time migration does need approximations, but the approximation can be made increasingly accurate.
  • Time migration distorts images, but the distortion can be removed with regularized inversion.

It was joy to listen to Sergey describe these observations through what he called beautiful equations: "the beautiful part about this equation is that it has no parameters", or "the beauty of this equation is that is does not contain velocity", an so on. Mad respect.

Seismic adaptive optics

Alongside seismic multiples, poor illumination, and bandwidth limitations, John Etgen (BP) submitted that, in complex overburden, velocity is the number one problem for seismic imaging. Correct velocity model equals acceptable image. His (perhaps controversial) point was that when velocities are complex, multiples, no matter how severe, are second order thorns in the side of the seismic imager. "It's the thing that's killing us, and that's the frontier." He also posited that full waveform inversion may not save us after all, and image gather analysis looks even less promising.

While FWI looks to catch the wavefield and look at it in the space of the data, migration looks to catch the wavefield and look at it at the image point itself. He elegantly explained these two paradigms, and suggested that both may be flawed.

John urged, "We need things other than what we are working on", and shared his insights from another field. In ground-based optical astronomy, for example, when the image of a star is be distorted by turbulence in our atmosphere, astromoners numerically warp the curvature of the lens to correct for rapid variations in phase of the incoming wavefront. The lenses we use for seismic focusing, velocities, can be tweaked just the same by looking at the wavefield part of the way through its propagation. He quoted Jon Claerbout:

If you want to understand how a horse runs, you gotta run along with it.

Big imaging, little imaging, and combination of the two

There's a number of ways one could summarize what petroleum seismologists do. But hearing (CGG researcher) Sam Gray's talk yesterday was a bit of an awakening. His talk was a remark on the notion of big imaging vs little imaging, and the need for convergence.

Big imaging is the structural stuff. Structural migration, stratigraphic imaging, wide-azimuth acquisition, and so on. It includes the hardware and compute innovations of broadband, blended sources, deblending processing, anisotropic imaging, and the beginnings of viscoacoustic reverse-time migration. 

Little imaging is inversion. It's reservoir characterization. It's AVO and beyond. Azimuthal velocities (fast and slow directions) hint at fracture orientations, azimuthal amplitudes hint even more subtly at fracture compliance.

Big imaging is hard because it's computationally expensive, and velocities are unknown. Little imaging is hard because features like fractures, faults and pores are at the centimetre scale, but on land we lay out inlines and crossline hundreds of metres apart, and use signals that carry only a few bits of information from an area the size of a football field.

What we've been doing with imaging is what he called a separated workflow. We use gathers to make big images. We use gathers to make rock properties, but seldom do they meet. How often have you tested to see if the rock properties the little are explain the wiggles in the big? Our work needs to be such a cycle, if we want our relevance and impact to improve.

SEG 2014: sampling from the smorgasbord

/

Next week, Matt and I will be attending the 2014 SEG Annual General Meeting at the Colorado Convention Centre in Denver. Join the geo-tweeting using the hashtag #SEG2014 and stay tuned on the blog for our daily highlights.

Fitness training

I spent a couple of hours yesterday reviewing the conference schedule in an attempt to form an opinion on what deserved my attention. The meeting boasts content from over 1600 abstract submissions which it has dispersed over three formats: oral presentations, poster presentations, and oral discussions/e-posters (looking forward to finding out how these work). Any given moment there will be 12 oral, 3 poster, and 6 e-poster presentations going on, not to mention all the happenings on the exhibition floor. A worthy test for my navigation skills, discipline, and endurance, as well as the new and improved SEG events mobile app.

The technical program

There are 101 sessions in the technical program, each with around 8 presentations. Six of these sessions are dubbed special sessions, hosting either invited speakers from other domains such as hydrogeophysics and completions engineering, or a heavyweight lineup of seismic celebs. Special session numero uno, entitled Recent Advances And The Road Ahead is  the session that I'm most looking forward to. It kicks off the technical program on Monday afternoon with talks from:

  • Christof Stork (ION Geophysical), The decline of conventional seismic acquisition and the rise of specialized acquisition: this is compressive sensing.
  • Sergy Fomel (UT Austin), Recent advances in time-domain seismic imaging. 
  • John Etgen (BP), Seismic adaptive optics. 
  • Kurt Marfurt (Univ. of Oklahoma), Seismic attributes and the road ahead. 
  • Reinarldo Michelena (iReservoir), Flow simulation models for unconventional reservoirs: The role of seismic data.

Other presentations throughout the week that have made it onto my must-see list:

  • Andreas Rüger (Halliburton), A practitioner's approach to full waveform inversion.
  • Lewis Li (Stanford), Uncertainty maps for seismic images through geostatistical model randomization.
  • Kevin Liner (Univ. of Arkansas), Study of basement rocks in Northeastern Oklahoma with 3D seismic and well logs.
  • Xinyuan Luan (China Univ. of Petroleum), Laboratory measurements of brittleness anisotropy in synthetic shale with different cementation.

To top it all off on Thursday afternoon, Matt and I will be at workshop number 9, Latest Developments in Time-Frequency Analysis. It is one of many post convention workshops worth sticking around for after the booths get torn down and the the exhibition doors close.
