In an effort to optimize drilling operations and economics, an operator examined the effect of adding hollow glass spheres (HGSs) directly to the drilling fluid instead of performing underbalanced drilling.

A panel of experts says US shale producers need to rethink their drilling and completion designs as problems mount for horizontal wells when they go on pump. Hanging in the balance is whether long-term production from many shale wells will be achievable.

While some standardization makes sense, it is important for the industry to implement cost-effective supply chain practices to efficiently deliver customization when it improves efficiency and increases production.

The mixed-salinity environment poses a significant challenge in petrophysics.

Coupled, full-field, integrated, holistic, or asset: Call it what you will, this class of modeling is becoming increasingly commonplace.

Recent experience with a newly introduced sampling-while-drilling service has shown that it is possible to make reliable downhole formation-fluid-property estimates during sampling-while-drilling operations.

The unconventional boom that has swept across North America over the past decade is a testament to how game-changing technology combined with expanded knowledge and understanding has transformed the paradigm of hydrocarbon production.

This paper describes the development of “digital-rocks” technology, in which high-resolution 3D image data are used in conjunction with advanced modeling and simulation methods to measure petrophysical rock properties.

This paper discusses ultradeep directional-resistivity (DDR) logging-while-drilling (LWD) measurements for high-angle and horizontal wells that have been applied recently with success on the Norwegian continental shelf (NCS).

Comprehensive formation evaluation is one of the technical focus areas that is fundamental across almost all upstream businesses.
