Geosteering – Popular Pitfalls, Realism, & Remedies

It’s all about drilling a hole in the right rocks. There might be bragging rights in the longest, deepest, most technical or fastest horizontal project, but not so much money. Our experience teaches that there are three broad categories of “Popular Pitfalls”, and there are strategies to mitigate these risks.

 

The most “Popular Pitfalls” fall into three general categories: 1) Over simplification of pre-drill subsurface geologic uncertainty and undue confidence in the pre-drill geologic model; 2) Over-confidence in the accuracy and completeness of while-drill data, including MWD-LWD logs, directional surveys, and the depth-specificity of mudlog data; 3) Procedural errors by the geosteering decision-maker, e.g. failure to account for well path positional uncertainty, fruitless over-steering, imprecise communications with drillers.

 

Several real-well examples will be displayed.

 

Remedies for these maladies are not entirely fool proof, but costs can be substantially controlled and in-target percentage can be greatly improved by applying work flows which recognize and sometimes repair these problem, or at least hedge against the unavoidable uncertainties.

President
BHL Consulting, Inc. & BHL Boresight, Inc.

Raymond Woodward received his geology degree from Baylor University in April, 1979, worked for various independent O&G exploration-production companies in exploration, exploitation, and supervisory roles until joining Sonat Exploration in 1987. Woodward spent 4 ½ years in Sonat’s Austin Chalk business unit immersed in horizontal geology, geosteering, and drilling. When Sonat liquidated to El Paso Corp in 1999, Woodward remained in Tyler, TX as an independent geologist-consultant, and quickly encountered a substantial demand for horizontal geologic consultation. BHL Consulting, Inc was incorporated in 2000. By 2004 Woodward had designed BORESIGHT Geosteering software for BHL’s consulting functions. The software company, BHL BORESIGHT, Inc, was spun off from the consulting group, and both companies have continued to grow. BHL Consulting now includes 13 consulting geologists steering roughly a half-million feet of lateral per month. Work history includes US Lower 48, Canada, and Morocco, in 14 different basins. BORESIGHT software accounted for over half of all horizontal wells in Texas and over a third of them nationwide, first 2 quarters 2013.
