Oil prices are high, but spending has not caught up—yet. Meanwhile, exploration strategies are changing around the world toward a lower-risk model, and the frenzied pace of US M&A has very much cooled off. -
This case study outlines a full-scale testing program focused on the behavior of thermal casing connections subjected to severe bending and low-cycle fatigue loading. -
With millions of wells having been drilled in the US since the beginning of the oil age, the land is pocked with old, unused wellbores. For most, repurposing is a pipe dream. Plugging is the best option. -
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives. -
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities. -
This case study presents the first field deployment of acoustic fracturing analysis to evaluate perforation efficiency and implement real-time interventions during pressure pumping.
-
The new era of Mexican oil exploration has officially begun, but not quite as the government had hoped. -
Petroleum engineering graduates, regardless of their country or university, are facing tougher competition for jobs this year.
-
Well control training programs for deepwater drillers and key rig personnel are undergoing a major overhaul that has been years in the making.
-
More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
-
The prospect of natural gas in a riser commonly summons up a vision of a deadly, fast-rising bubble exploding on to the floor of a drilling rig. But comments by consultants on an OTC panel argued that it is a poor description of how gas behaves in a deepwater riser.
-
After the 2010 subsea blowout of the Macondo well that resulted in 11 deaths and the worst oil spill in US history, early kick detection technology found itself at the top of the wish list for regulators and offshore companies seeking to avoid similar accidents.
-
For years, the oil and gas industry has used autonomous underwater vehicles (AUVs) for simple tasks such as underwater surveys and inspection.
-
Researchers at the University of Texas at Austin (UT) have set an audacious goal to halve the time, cost, and number of rig personnel required for drilling every type of well, from unconventional shale to ultradeepwater.
-
Offshore drillers have been battered by the plunge in oil prices with falling day rates and a growing number of older rigs headed for demolition.
-
“The most powerful brands are created and maintained by delivering distinctive and consistent experiences to the market.”
