Instructor(s): Larry Britt, Thomas (Tom) Harting
|Horizontal wells have become the industry standard for unconventional and tight formation gas reservoirs. Because these reservoirs have poorer quality pay, it takes a good, well-planned completion and fracture stimulation(s) to make an economic well. Even in a sweet spot in the unconventional and tight gas reservoir, good completion and stimulation practices are required; otherwise, a marginal or uneconomic well will result. But what are good completion and stimulation practices in horizontal wells in these unconventional reservoirs? What are the objectives of horizontal wells and how do we relate the completion and stimulation(s) to achieving these goals? How many completions/stimulations do we need for best well performance and/or economics? How do we maximize the value from the horizontal wells? When should a horizontal well be drilled longitudinally or transverse? These are just a few questions to be addressed during this course. This course will focus on some of the key elements of well completions and stimulation practices as they apply to horizontal wells in tight and unconventional reservoirs. 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. This course also will address key risks to horizontal wells and develop risk mitigation strategies so that project economics can be maximized. In addition, tight and unconventional gas field case studies will be used to illustrate the application of these design, optimization, and risk mitigation strategies for horizontal wells in tight and unconventional gas reservoirs.|

You Will Learn:
MR. LARRY K. BRITT is an engineering consultant with NSI Fracturing, and President of Britt Rock Mechanics Laboratory at the University of Tulsa. 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'. Larry is a distinguished member of the SPE and co-author of '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 BS in Geological Engineering and a Professional Degree in Petroleum Engineering. He is an adjunct professor in the Petroleum Engineering Department at MS&T where he also serves on both the Petroleum Engineering and University Engineering Advisory Boards and is a member of the Academy of Mines and Metallurgy.
MR. TOM HARTING is a completion engineering consultant with over 34 years of experience in completion, production, and operations engineering, covering the lower onshore 48 states and Alaska. This includes the design and implementation of wireline, coil tubing, snubbing, and well service operations. Tom retired in 2009 from BP, where he was the Completion Wells Team Leader for BP's largest Tight Gas Development. His career with Amoco and BP has entailed developing high angle well designs and new completion technology for tight and unconventional gas reservoirs. He has also developed learning programs and operational guidelines for the execution of fracture stimulations. Tom has published SPE papers regarding multilateral completions, micro seismic, and the application of mini-falloff test for tight gas wells. He graduated with a BS in Petroleum Engineering from the University of Tulsa.
