Luke Eaton of ConocoPhillips, Darryl Herrington of LLOG Exploration, and John Thorogood, drilling global consultant provide their perspectives on deepwater technologies.

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.

Global decommissioning projects are ramping up as many installations near the end of their life cycle. Many operators are now planning for major removal projects. Changes in technology and regulations have caused operators to make significant shifts in well abandonment operations.

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?

Advances in drilling and reaming with casing or liners (DwC, DwL, RwC, and RwL) are yielding unprecedented capabilities in well design and construction.

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.

Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.

One of the most innovative recent advances in downhole drilling tool activation has been the introduction of mechanical extrusion technology, incorporating the use of rigid metal darts to improve the cycling and control of a variety of processes and devices.

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

This paper provides details of comprehensive computational-fluid-dynamics (CFD) -based studies performed to overcome the separation inefficiencies experienced in a large-scale three-phase separator.
