This paper explores the applications, benefits, and value of a high-build-rate rotary-steerable system (HRSS) capable of delivering dogleg severity (DLS) greater than 18°/100 ft.

Geophysicists from Stanford University have compiled a map of new maximum horizontal stress orientations in Texas and surrounding areas, potentially giving operators new information for avoiding seismic activity in their hydraulic fracturing operations.

This week the US Geological Survey (USGS) reported that the Wolfcamp shale holds 20 billion bbl of technically recoverable oil. This builds on other active formations in the Permian Basin, where nearly half of US active rigs are operating.

Bernard J. Duroc-Danner has stepped down as chairman, chief executive officer (CEO), and president at Weatherford. Duroc-Danner had served in those positions since 27 May 1998. He joined the company in May 1987 to initiate the startup of EVI's oilfield service and equipment business. He was elected EVI's president in January 1990 and CEO in May 1990. He serves on the …

Drillstring vibration is a leading cause of downhole-tool failure and premature wear of downhole equipment.

The Wyoming Department of Environmental Quality recently concluded that hydraulic fracturing operations were not the likely cause of well water contamination in a small town.

Sourcing water for large multifracture stimulations in west Texas is a well-known constraint on oil and gas activities in the area. A 6-month pilot operation demonstrated that produced-water reuse is technically feasible and can be a cost-effective solution.

A team of oil and gas consultancy companies have formed a collaborative program aimed at offering integrated support for operators looking to retire redundant facilities without in-house overhead.

For nanotechnology-based drilling fluids, acceptance means proving they can outperform other drilling fluids. Initial results have been encouraging enough to move toward commercialization.
