Geo-Texture Technologies - Houston, Texas

Geologists and geophysicists have been sold on running lots of attribute cubes -- up to 200 or more. Then what do they do? The interpreter examines them and confirms that some appear to correlate visually to “ground truth.”

But how well do they really correlate – and has the ground truth been carefully normalized?

What one would really like to obtain is Reservoir Properties From Seismic attributes (RPFS) to deliver true meaningful maps for the drilling teams to help design their development drilling and completion plan. Geoscientists receive hundreds of attribute cubes and most of them don't have any value with regards to their prospect. Geo-Texture has discovered that the maximum value usually is derived from several cubes combined optimally to yield more accurate predictions that no single volume can by itself -- as well as quantifying prediction confidence.

Generating attribute volumes is only the first step. Geo-Texture now provides the valuable service of prioritizing and mining these cubes -- along with other data -- for ground truth Reservoir Properties From Seismic attributes (RPFS) for exploration and development companies.

The example above used a Neural Net. However we have subsequently created a proprietary method that in several areas has proved superior to Neural Nets. We take the optimized best 3D attributes, including any forward modeling or pre-stack results, and calibrate it with the normalized ground truth to extend that ground truth away from the well bore. We also generate “error maps” created using a multiple blind test of each point of ground truth. This method has to date proven beneficial for all areas with 3D seismic and well control – even in fractured shale plays.
