Dual-Gradient Drilling Debuts in Gulf of Mexico

Statoil has successfully used dual-gradient drilling for the first time ever in the US Gulf of Mexico (GOM) on an upper-hole section.

MPD/UBD

Single-Gradient Subsea-Mud-Lift-Drilling Technology in Deepwater Gulf of Mexico

As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.

Sustainability and the Role of Petroleum Engineers

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?

Surviving the Downturn

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.

Fracturing/pressure pumping

Pushing the Limits of Deepwater Stimulation

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.

Bayesian-Style History Matching: Another Way To Underestimate Forecast Uncertainty?

This paper critically investigates the impact of using realistic, inaccurate simulation models. In particular, it demonstrates the risk of underestimating uncertainty when conditioning real-life models to large numbers of field data.
