Tanya J. Gallegos – Distribution and character of hydraulic fracturing operations in the U.S. since 1947: AAPG Solving Water Problems
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. Here 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. Nearly 1 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, and 14. Arkoma Basins and the 15. Cherokee Platform. During this time period, the use of horizontal/directional drilling of hydraulically-fractured wells rose from 6 to 42 percent. These horizontal wells utilize an average of nearly 38 times greater fluid volumes than vertical wells, yet most hydraulic fracturing occurred in vertical wells. These recent advancements in hydraulic fracturing and directional/horizontal drilling have led to the expanded recovery of the once-inaccessible unconventional oil and gas resources.
This year’s Solving Water Problems in Oil and Gas Production GTW has a truly stellar slate of presentations – all of which allow you time to ask questions, discuss, and learn. Space is limited, so sign up today. Don’t miss this amazing speaker and presentation our Solving Water Problems in Oil and Gas Production – Fort Worth, TX, February 26-27, 2013!
Tanya J. Gallegos is a research engineer at the U.S. Geological Survey in Denver, CO. She received a PhD in 2007 from the University of Michigan and an M.S. from the University of New Mexico in 1997. She is a registered professional Environmental Engineer in the State of New Mexico. Her research encompasses field and lab studies to understand environmental implications of energy resource development, such as hydraulic fracturing and uranium extraction, throughout the resource development life cycle, with emphasis on solid-phase characterization of contaminant sources, geochemical and isotopic indicators and rock-water interactions.
