Carbonate reservoir evaluations for either Exploration or Production studies are markedly different than those for clastic ones because of several important factors:

Heterogeneity in carbonate reservoirs contributes to large ranges in hydrocarbon production rates. Reservoir heterogeneity is generated by processes related to deposition, diagenesis and structuring.

Fracture modeling has become a vital part of successful drilling, completion, and ongoing stimulation of shale plays, as well as other unconventionals. It is also important in optimizing recovery in mature fields. Welcome to an interview with Ahmed Ouenes, CEO and Founder of FracGeo.

New products can revitalize under-performing wells in mature fields. However, it is important to understand precisely why the well is not producing and to select the treatment that will work for the unique conditions of the well.

Welcome to an interview with Olivia Carey, who has committed herself to finding new solutions for wells in need of revitalization. She discusses the products, candidate wells, and increased production using new products.

There may be job openings on Capitol Hill as some Senators and Representatives, and their staffs are replaced after the election. If you want to apply for one of those staff jobs check out HillZoo.com.

Those of us in the petroleum industry have been tracking the rapid expansion of oil and gas production from shales and in the process we may not have noticed the rapid expansion of renewable energy, especially wind. Read the latest Energy Information Administration (EIA) statistics.

China plans to significantly increase its natural gas consumption to help cut its appalling air pollution. But natural gas is still a small part of its energy mix. In addition, and to confound environmentalists, a significant part of China’s gas supply comes from Coal-to-Gas technology, which generates large volumes of greenhouse gas and other pollutants, but does allow China to deliver clean-burning gas to locations with severe air pollution.

West Edmond field, located in central Oklahoma, is one of the largest oil accumulations in the Silurian–Devonian Hunton Group in this part of the Anadarko Basin. Production from all stratigraphic units in the field exceeds 170 million barrels of oil (MMBO) and 400 billion cubic feet of gas (BCFG), of which approximately 60 MMBO and 100 BCFG have been produced from the Hunton Group. Oil and gas are stratigraphically trapped to the east against the Nemaha uplift, to the north by a regional wedge-out of Hunton strata, and by intraformational diagenetic traps. Hunton Group reservoirs are the Bois d'Arc and Frisco Limestones, with lesser production from the Chimneyhill subgroup, Haragan Shale, and Henryhouse Formation.

Hunton Group cores from three wells that were examined petrographically indicate that complex diagenetic relations influence permeability and reservoir quality. Greatest porosity and permeability are associated with secondary dissolution in packstones and grainstones, forming hydrocarbon reservoirs. The overlying Devonian–Mississippian Woodford Shale is the major petroleum source rock for the Hunton Group in the field, based on one-dimensional and four-dimensional petroleum system models that were calibrated to well temperature and Woodford Shale vitrinite reflectance data. The source rock is marginally mature to mature for oil generation in the area of the West Edmond field, and migration of Woodford oil and gas from deeper parts of the basin also contributed to hydrocarbon accumulation.
