Larry K. Britt, is an engineering consultant with NSI Fracturing and President of Britt Rock Mechanics Laboratory at Tulsa University. Since joining NSI in early 1999, Larry has specialized in the development and application of tools for the post appraisal of hydraulic fracturing stimulations. Britt’s experience includes the optimization, design, and execution of fracture stimulations and integrated field studies throughout the world. Prior to joining NSI he worked for Amoco Production Company for nearly twenty years. During the last six years with Amoco, he was fracturing team leader at Amoco’s Technology Center in Tulsa, Oklahoma, where he was charged with managing the development and application of fracturing technology for Amoco’s worldwide operations. Larry is the co-author of the SPE book “Design and Appraisal of Hydraulic Fractures.” He has served twice as an SPE Distinguished Lecturer, as a JPT editor on “Hydraulic Fracturing” and on numerous SPE Forum Committees on Gas Reservoir Engineering and Hydraulic Fracturing. In addition, Larry has authored over thirty technical papers on reservoir management, pressure transient analysis, hydraulic fracturing, and horizontal well completion and stimulations. He is a graduate of the Missouri University of Science & Technology (MS&T) where he has a B.S. in Geological Engineering and a Professional Degree in Petroleum Engineering. He is an adjunct professor in the Petroleum Engineering Department at Tulsa University and MS&T where he also serves on both the Petroleum Engineering and University Engineering Advisory Boards.


Full Description
The geomechanics associated with oil and gas reservoirs has always been an issue even in vertical wells. However, now that seventy percent of all wells and nearly one hundred percent of wells in unconventional reservoirs are drilled horizontally it has become an even more important issue. After all, horizontal wells have become the industry standard for unconventional and tight formation oil and gas reservoirs. Why are the geomechanics and stress state important? How does the geomechanics impact the well completion and stimulation? What role does geomechanics play with regard to the creation of complexity? How can an understanding of the geomechanics be used to increase the profitability of an unconventional resource? These are just a few questions to be addressed during this presentation.
This presentation will focus on some of the key elements of the reservoir such as geomechanics and permeability and how they apply to horizontal well completions and stimulation practices. The stress state will be addressed to understand the effect of hoop stresses on breakdown pressures and determine the impact on completion and stimulation staging. It will be used to assess reservoir complexity and completion practices such as simul-frac’s, zipper frac’s, bashing, and natural fissure behavior. Optimization studies will be shown and used to highlight the importance of lateral length, number of fractures, inter-fracture distance, fracture half-length, and fracture conductivity. These results will be used to discuss the various completion choices such as cased and cemented, open hole with external casing packers, and open hole “pump and pray” techniques.
