The shale boom has propelled the United States oil and gas industry to a leading position, not just in production, but also in navigating the perilous waters of public opinion.

While exploration has slowed in many parts of the world in response to the industry’s lagging downturn, India is moving full steam ahead to encourage exploration and production on a domestic and international scale.

The search for unconventional hydrocarbons is not new. It’s true that almost 100 years separated the early exploration successes in the synclinal valleys of Central Pennsylvania, to the exploitation of Coal-Bed Methane in a number of basins in the U.S. and Canada in the 1980’s. Since the 1980's, however, a quiet revolution began which by today has seen several waves of unconventional resources being pursued with economic success. Coal-bed methane was followed by the search for Center-Basin Gas, Shale Gas and most recently, Liquid-rich Shales (some of which aren't shales).

The past 30+ years have witnessed a wide variety of exploration strategies and a number of technological “revolutions” in the search for oil and gas. Although the exploration landscape and tools of the trade are so different than they were in the early 1980’s, in one aspect we appear to have come full circle, realizing that a deep understanding of our basins is the critical element in any success.

Marita Bradshaw, an AAPG member and retired geologist with Geoscience Australia, has spent her career helping to uncover Australia’s oil and gas potential and is now pleased to see recent large discoveries on the continent and the expansion of the export LNG industry. A symposium will be held in her honor this month at the AAPG-SEG International Convention and Exhibition (ICE) in Melbourne.

In the coming year, the Energy Minerals Division is looking to improve and expand its information delivery system. EMD also is seeking volunteers to fill a number of vacant section and region councilor positions.

AAPG offers two short courses in conjunction with this year’s Unconventional Resources Technology Conference (URTeC). A wealth of information in a short period of time, theses short courses are an effective and efficient way to learn about the industry.

This year, URTeC has added an enhanced preview of “Coming Attractions.” In addition to looking at established plays, URTeC will provide significant information about emerging unconventional resource possibilities in North America and around the world.

The influence of moisture, temperature, coal rank, and differential enthalpy on the methane (CH4) and carbon dioxide (CO2) sorption capacity of coals of different rank has been investigated by using high-pressure sorption isotherms at 303, 318, and 333 K (CH4) and 318, 333, and 348 K (CO2), respectively. The variation of sorption capacity was studied as a function of burial depth of coal seams using the corresponding Langmuir parameters in combination with a geothermal gradient of 0.03 K/m and a normal hydrostatic pressure gradient. Taking the gas content corresponding to 100% gas saturation at maximum burial depth as a reference value, the theoretical CH4 saturation after the uplift of the coal seam was computed as a function of depth. According to these calculations, the change in sorption capacity caused by changing pressure, temperature conditions during uplift will lead consistently to high saturation values. Therefore, the commonly observed undersaturation of coal seams is most likely related to dismigration (losses into adjacent formations and atmosphere). Finally, we attempt to identify sweet spots for CO2-enhanced coalbed methane (CO2-ECBM) production. The CO2-ECBM is expected to become less effective with increasing depth because the CO2-to-CH4 sorption capacity ratio decreases with increasing temperature and pressure. Furthermore, CO2-ECBM efficiency will decrease with increasing maturity because of the highest sorption capacity ratio and affinity difference between CO2 and CH4 for low mature coals.
