When a gas lift system starts performing poorly, there is a good chance no one will notice. It is not an event that demands attention like a broken pump. A gas lift system will continue injecting gas into wells and oil will continue to come out. Just not as much oil as there could be.

Moving to higher-capacity wellhead systems for high-pressure and high-temperature (HP/HT) environments will require a larger mandrel and conductor-casing size.

This paper identifies current development paradigms and discusses the future challenges in well planning, product development, and regulation.

The United States’ liquids-rich shale experience has been dominated by three major plays: the Eagle Ford Shale in south Texas, the Permian Basin in west Texas, and the Bakken Shale that straddles North Dakota and Montana.

The engineering, design, qualification, and implementation of drilling, completion, production, and intervention equipment for high-pressure/high-temperature (HP/HT) developments present significant challenges.

Some think oil and gas have little role in a sustainable ­future; global realities suggest otherwise. How is it that a finite energy resource and a source of greenhouse gas emissions can be part of a sustainable future?

The recent IHS CERAWeek conference in Houston brought ­together high-level executives. Over 5 days of discussions and panel sessions, several key themes emerged about the current state of the global oil and gas industry.

The lower tertiary formation found in the pre-salt layers of the Gulf of Mexico has become a proving ground for extending what is possible when completing multistage fracturing in ultradeepwater wells.

Implementation of new technology can require that leadership and key team members be willing to step outside their comfort zones.

In this paper, the authors introduce a novel semianalytic approach to compute the sensitivity of the bottomhole pressure (BHP) data with respect to gridblock properties.
