This month's speaker is George Waters with Schlumberger, and the topic will be "Completion of Hydrocarbon-Bearing Shale Reservoirs".
George Waters, Schlumberger Oilfield Services
The development of source rocks as commercial hydrocarbon resources has dramatically affected the production of natural gas in the United States. Production from gas shales has increased three fold in 10 years to approximately 1 TCF in 2007. Gas-in-place is now estimated at 580 TCF with EURs ranging from 31 to 76 TCF, and continuing to grow as more gas shale reservoirs are developed.
While the hydrocarbons contained in these reservoirs can be vast, recovery factors are quite low because of the completion process. Economically generating a large surface area exposed to a pressure drop via hydraulic fracturing is key to the commercial development of these plays. To do this effectively requires some rethinking of long held beliefs concerning hydraulic fracturing. Is a planar fracture optimal? Are proppants needed to achieve the required fracture conductivity? Can fracturing fluid compatibility issues be overcome in argillaceous rocks? How is a vast surface area created economically?
Innovative completion technologies, frequently employing horizontal wells, are being employed successfully to address these issues. Yet all shales are not alike. Thus, a successful technology in one shale gas basin may not be viable in others. When the key production drivers for a specific reservoir are clearly identified the most applicable completion technologies can be employed. This presentation focuses on the key stimulation issues associated with gas shale reservoirs and how to determine the appropriate completion methodology.
George Waters is the North American Stimulation Domain Manager for Schlumberger in Oklahoma City. He joined Dowell Schlumberger in 1985 and has held numerous completion engineering assignments since 1992, focusing primarily on low permeability hydraulic fracture optimization. Since 2000 he has concentrated on evaluation and completion of shale gas reservoirs. More recently he has focused on low permeability horizontal well evaluation and completion. He has published numerous technical papers and made multiple industry presentations on the stimulation of low permeability reservoirs. He holds a BS degree in petroleum engineering from West Virginia University, an MS degree in environmental engineering from Oklahoma State University, and an MS degree in petroleum engineering from Institute Francais du Petrole.

2009-2010 SPE Distinguished Lecturer
How to Prevent the Loss of Oil and Gas Production Caused by Scale Deposits
Charles Hinrichsen, Chevron Energy Technology Company
For most companies, oil production is usually a process that should really be referred to as “oil and water production!” Any system designed for oil production must be equipped to handle the vast quantities of water that are also produced. It is the presence of water that gives rise to numerous problems such as mineral scale deposition. The formation of mineral scale deposits on tubing, casing, perforations, and even on the formation face itself, can severely constrict fluid flow and thereby curtail the production rate of wells. In addition to lost production, a considerable portion of the workover budget is expended in efforts to remove these deposits and prevent their recurrence. As a consequence, scale prevention has been, and continues to be, a common enough exercise, and is successfully applied in many areas.
Scale can be controlled in two ways: by pre-treating the water, which can include such methods as water softening; or, more commonly, by the using scale inhibitors to reduce a brine’s scaling potential.
This presentation will review the major elements that normally comprise any effort aimed at the successful control of scale deposition, starting with scale identification, followed by scale prediction, inhibition, and removal. Several case histories will illustrate the application of these scale control techniques in oil production facilities.
Although the principles behind scale formation and prevention are generally well understood, there are many new forms of scale prevention and scale inhibitor application technology. Some people consider scale prevention a mature subject matter with "nothing new under the sun," but in fact there are many new developments - some of which I intend to highlight. Basically, scale formation can be a show stopper (e.g., those West African fields where the barium concentrations are quite high). If properly managed, however, scale can be prevented economically.
Charles Hinrichsen earned a BS degree in chemistry from the State University of New York and an M.S. and Ph.D. degree in chemistry from Cornell University in Ithaca, New York. He has worked at Chevron for more than thirty years and is currently based in the corporation’s Energy Technology Company as a chemical treating specialist. From 1998 to 2001 he coordinated Texaco’s chemical alliance operations in Angola, West Africa and from 2001 to 2003 he served as senior corrosion and chemical treating engineer in Wafra, Kuwait. He has more than 27 years' experience in scale and corrosion control treatment. In addition to his research and extensive technical service activities in support of Chevron’s production operations, both domestic and worldwide, he has presented many scale and corrosion related courses throughout the United States, Saudi Arabia, Kuwait and Indonesia. He is a member of the Society of Petroleum Engineers, the American Chemical Society and the National Association of Corrosion Engineers.

2009-2010 SPE Distinguished Lecturer
Realizing Full Potential of Hydraulic Fracturing – Damage Mechanisms and Mitigation
Joseph Ayoub, Schlumberger
Hydraulic fracturing has been successfully applied for decades to improve the economics of oil and gas production. Significant improvements in modeling, materials, delivery equipment, and monitoring have taken place, and the technology footprint has gone beyond tight or unconventional gas into higher permeability reservoirs such as the frac and pack applications.
Despite its tremendous success, hydraulic fracturing does not generally deliver the full potential expected. This has been recognized and the literature gives many examples of treatments where the production or well test data indicate an effective fracture length much lower than that predicted from the placement data. While many factors could contribute to this discrepancy including use of the wrong models or data interpretation, the different damage mechanisms that accompany hydraulic fracture treatments would also prevent achievement of the full potential.
In this lecture, the different damage mechanisms are reviewed and their impact quantified using a customized 3D multiphase reservoir simulator. Of particular interest is the new understanding of the damage caused by the fracturing fluid polymer concentration effect. This understanding resulted from an extensive experimental study run under a JIP that started in 2002. The experiments indicate that contrary to the common practice of calculating an average polymer concentration, the polymer concentrates only in the filter cake. They also show that significant yield stress effect is observed in the proppant pack whenever the filter cake thickness dominates the proppant pack width. Such yield stress effect results in only a fraction of the fracture length contributing to the flow rate for periods that can exceed years of production. Additional experiments indicate that delivering breakers into the filter cake, for example as fluid loss additive, is the most effective method to reduce the yield stress and restore production from the full length of the fracture. Supporting data as well as field examples of “coherent” versus erroneous fracture length estimates are discussed.
Joseph Ayoub is currently the reservoir engineering domain career leader for Schlumberger Oilfield Services based in Houston, Texas. He has held many engineering and operations posts in the US, Europe, Africa, and the Middle East. Joseph has taught numerous industry seminars and published well over 25 papers, mainly in the areas of well testing, hydraulic fracturing, and frac and pack. His involvement was instrumental for introducing the pressure derivative method and for launching the frac and pack technique in the GOM in the early 1990. More recently, Ayoub formed and led the work of a JIP on fracture clean-up that resulted in significant discoveries on fracture fluid damage mechanisms and mitigation. Joseph was named Schlumberger Advisor in 1999 and SPE Distinguished Member in 2005. He has served on numerous SPE committees and is often invited as discussion leader to SPE forums. He served as SPE Distinguished Lecturer in 1998-1999.

This month's speaker is Jay Portwood with Eclipse. The topic is "Polymers: Water Shutoff in the Barnett and Waterflood Conformance".
HOW POLYMER GELS ARE BEING USED IN OUR OWN BACKYARD TO IMPROVE SECONDARY OIL RECOVERY AND TO REDUCE WATER PRODUCTION FROM HORIZONTAL GAS WELLS
By Jay Portwood – Eclipse IOR Services
This presentation will discuss how polymer gel technology is being used in mature waterfloods to divert injection into by-passed areas of the reservoir, resulting in sharply higher oil production, lower WOR, higher oil-cut percentage, and improved ultimate recovery. The presentation will also include Information related to work that has been done using a polymer process to reduce unwanted water and increase gas production from horizontal Barnett Shale wells, where fracture stimulation treatments accidentally propagated into the underlying Ellenburger formation.
Biographical Summary for Jay Portwood
Mr. Portwood received a BS in geology from the University of Texas at Austin in 1983. He began his career working as an exploratory and development geologist in the Mid-Continent and Permian Basin areas of the U.S., but in 1989, he moved to the service sector where he has spent the last 20+ years designing and applying enhanced oil recovery chemical processes including, but not limited to surfactant, polymer and cross-linked polymer gels to improve volumetric sweep efficiency and oil recovery from waterfloods and CO2 floods, to improve water injectivity into low permeability waterflood reservoirs, and to reduce unwanted water production in oil and gas wells. In 2007, he started Eclipse to provide a full line of IOR/EOR services, with company headquarters located in the DFW suburb of Keller. Mr. Portwood has authored numerous technical papers and articles dealing with the practical application of chemical improved oil recovery techniques, and has participated as an instructor and presenter at many seminars, workshops and professional meetings.
