Unconventional resources offer many substantial benefits, yet the rapid increase in production of these resources using hydraulic fracturing has generated scrutiny by some policymakers and advocates who cite health concerns.

Dual-gradient drilling has long been described as the drilling method of the future for challenging offshore wells. Now, indications show it could start being used with some regularity.

The benefits of modern industrial control systems have never been greater. A baseline system security image, as a start, allows a vessel owner or operator to understand the security risks.

Every process plant presents a high number and diversity of valves that control the flow of feedstock, products, and service liquids and gases.

Colorado will become a testing ground for reducing emissions from oil and gas exploration and production (E&P).

Growth in enhanced oil recovery (EOR) projects using carbon dioxide (CO2) in west Texas could be limited by supplies unless new sources of the gas are found in the ground or from indus- trial facilities.

Oxane Materials has joined the 20,000 club—joining the two makers who have announced they are selling proppant capable of standing up to high pressures.

For those in shale exploration, “fracability” is a real word, a critical property, and a point of contention.

Multilayered metal-mesh screens (MMSs) are widely used as standalone screens for sand control in unconsolidated formations. It is often found that screens with the same filter-layer nominal rating perform differently.

This paper presents a combined experimental and numerical-modeling study on sand-screen performance. The objective is to develop an improved methodology for optimal sand-screen-aperture selection by addressing some of the limitations present in existing sand-retention tests.
