There is no doubt that the 86,000-sq-mile Permian Basin, encompassing 52 counties in west Texas and eastern New Mexico, is experiencing a renaissance in drilling activity.

What gave rise to oil drilling in the Permian Basin—in particular the Spraberry trend area? Why now the focus on the various Wolfcamp plays?

Pioneer Natural Resources is a large independent oil and natural gas company, with resources throughout the US—in south Texas, the Rockies and Mid-Continental regions, the Barnett shale, and in Alaska’s Oooguruk field.

Coalbed methane development can require a large volume of wells, but the costs of logging can be prohibitive, so alternate formation-evaluation solutions are being evaluated. This paper compares state-of-the-art mining logging technology with conventional oil-and-gas approaches.

Approach Resources Inc. is an independent oil and natural gas company headquartered in Fort Worth, Texas.

Wireline continuous coring (WCC) has been adapted from the mining industry for unconventional resources. This paper is aimed at identifying and addressing complications experienced in the use of WCC.

A new multilayer boundary‑detection service has been introduced to resolve the geological uncertainty associated with horizontal wells in Bohai Bay. Geosteering and real time reservoir characterization were used to reduce the uncertainty.

Saturation-height functions (SHFs) play a key role in reservoir description and in quantifying oil in place. The functions must compare well with other sources of water saturation (Sw), such as core measurements and well-log interpretations. This study reconciles different sources of Sw.

Successful rejuvenation of two declining fields was enabled through innovation in both engineering and procurement strategy.

The deepwater industry uses technology qualification (TQ) as a tool to determine which safety barriers are needed, and what level of testing is required. Even without failure data from the field, a method has been developed to quantify the integrity of various components.
