Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.
Geophysicist Markos Sourial discusses advances in seismic imaging, the challenges of modern data processing, and what they mean for the next wave of subsurface professionals.
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.

Because of inherent complexities, understanding the characteristics of perforations in downhole environments is a significant challenge. Perforation-flow laboratories have been used to provide insight into cleanup and productivity mechanisms around perforation tunnels. -
Falling oil prices are the acid test of drilling efficiency. SPE Technical Director Jeff Moss of ExxonMobil talks about ways to build in lasting savings as part of this special report.

The latest example of the offshore sector's march toward automated wellbore construction will take shape later this year in the North Sea.
-
This paper describes how a technique known as applied-surface-backpressure managed-pressure drilling (ASBP-MPD) can alleviate the limitations of conventional deepwater well control.
-
A contest where teams of college students design and build an automated drilling rig able to deal with hazardous obstacles in a test block, showed how a small change can be engineered to matter.

SponsoredNew extreme environment ultracapacitor technology will allow directional drillers to eliminate lithium from their entire supply chain. These advanced ultracapacitors can be coupled with downhole turbine generators to provide reliable downhole power without the need for lithium.
-
Since the 1980s, many technical works have focused on improving the ability to detect hydrocarbons inside the riser and safely remove them from the system. This trend gained extra momentum with the advent of systems such as riser-gas handlers and managed-pressure drilling.

The Pluma-1 discovery could turn the southeast portion of Stabroek Block off Guyana "into a major new development area," the company says.
-
Operators face a dilemma in balancing the need for mud weight (MW) to remain below the fracture gradient to avoid losses, while also providing sufficient density to block influxes into the well.
