    As we deplete conventional gas reserves, unconventional gas resources are becoming increasingly important to U.S. and international energy supplies. For example, U.S. dry gas reserves have increased annually over the past 12 years, mainly due to reserves growth from shale gas. Today, shales, coal beds, and low-permeability (tight) sandstones, combined, account for approximately 50% of the U.S. natural gas production. From ~365 billion cubic feet (Bcf) per year in 2000, shale gas production grew to about 5.5 trillion cubic feet per year (Tcf/yr) by year-end 2010 when it accounted for approximately 25% of all U.S. dry gas production. In 2009, U.S. production of coalbed methane, alone, exceeded 1.9 trillion cubic ft (Tcf), which was ~9% of the total U.S. dry gas production, and coalbed methane reserves were 18.6 Tcf, or 6.8% of the total U.S. dry gas reserves.

    Internationally, there are tremendous unconventional gas resources that have been subject of only cursory or no assessments and have been exploited only locally. While resources of unconventional gas are very large, economically recoverable volumes (reserves) are much smaller, due to low reservoir permeability. Because most unconventional gas reservoirs have low matrix permeability, natural fractures may be necessary for economic production rates. In addition to understanding of the role of natural fractures in fluid flow, economic production of unconventional gas reservoirs requires adequate gas prices and application of cuttingedge technology. Knowledge of the optimal drilling, completions, fracture stimulation techniques, and production methods are necessary for successful exploitation of specific low-permeability reservoirs.

    This course is designed to benefit multidisciplinary asset teams including: geologists and geophysicists; reservoir, drilling, production, completion and facilities engineers; and man-agers.
