How bad is it?



Updated through 21 May 2016

Bankruptcies: SandRidge, Halcon, Energy XXI, Aztec Oil & Gas, Breitburn Energy Partners LP, Penn Virginia Corp., Linn Energy, etc... altogether 27 companies field for bankruptcy in April 2016 and 69 since the beginning of 2016. Compare that to the 42 that filed in 2015 (source).

Layoffs: Estimated at 350,000 worldwide (source)

To paraphrase SPE 2016 President Nathan Meehan: If we include cable tool rigs, total US activity has exceeded 500 rigs since Abraham Lincoln was the US President. The current (5/20/2016) North American rig count stands at 404, making it a truly historic low.

This graph captures the current deep decline in world oil price (WTI, but Brent would be similar), North American natural gas price and North American rig count. The rig count is a macro measure of economic activity in the hydrocarbon energy sector, the center of an ecosystem of exploration and production business activity. The rig count still falling after 12 months may indicate the quickest possible recovery could be 12-18 months away.

3D Seismic Interpretation class 2016

We have just completed the 2016 version of 3D Seismic Exploration, a graduate-level class in the Geosciences Department at the University of Arkansas. This was the first time the course used OpendTect interpretation software. We had some recurring issues with network licensing and crashes on some computers, but overall it was an excellent experience. My advice... just give the students access to the base OpendTect Pro system and forget about network licenses to advanced functions. Most of the attributes you want (similarity, energy, spectral decomposition) are right there in the base system. 

I need to make a special shout-out to Mac Macgilvery for bringing insight and deep geological knowledge to the class from his long and distinguished career at Tenneco, Shell and ConocoPhillips. Not to mention a PhD from the University of Texas. Thanks Mac, it is great to have you back home in Fayetteville.


Bryan Bottoms was winner of Best Prospect Award for Banzai!!. The wise owl of accomplishment was gifted to the winner.

OpendTect Workflows

I've been developing OpendTect workflows to support my graduate student's research and my University of Arkansas course 3D Seismic Exploration. These are posted and maintained on my Grad Student Blog and links to those blog entries will be given here and updated as new workflows come online.

These may be of some use to those academics and others out there using OpendTect for teaching, research, hydrocarbon exploration or any other application of seismic interpretation.
