Geologists, engineers, geochemists, and others who are interested in learning about advances in hydraulic fracturing, and findings about the relative effectiveness of various approaches, techniques, and procedures in different basins in the U.S.
Hydraulic fracturing is presently the primary stimulation technique for oil and gas production in low-permeability, unconventional reservoirs and has also been used to improve yields from conventional reservoirs. We present a National-scale data analysis of the trends in hydraulic fracturing locations in the United States and treatment characteristics since 1947, including drill-hole direction, treatment fluids, additives, propping agents, and water utilization. One million wells drilled from 1947 through 2010 have received over 1.6 million hydraulic fracturing treatments. Between 2000 and 2010, the most active areas of production in the United States were within the following provinces: 1) Appalachian, 2) Southwestern Wyoming, 3) Bend Arch-Ft. Worth, 4) Permian, 5) Uinta-Piceance, 6) San Joaquin, 7) Denver, 8) Williston, 9) Michigan, 10) Black Warrior, 11) Raton, 12) San Juan, 13) Anadarko, 14) Arkoma Basins and 15) the Cherokee Platform. During this time period, the use of horizontal/directional drilling of hydraulically-fractured wells rose from 6 to 42 percent. Horizontal wells utilize an average of nearly 38 times greater fluid volumes than vertical wells, yet most hydraulic fracturing occurred in vertical wells. Recent advancements in hydraulic fracturing and directional/horizontal drilling have led to the expanded recovery of once-inaccessible unconventional oil and gas resources.
Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).
