Unwanted water production can erode well performance and asset economics if left unmanaged. Interwell’s precision water shutoff approach, grounded in diagnostics and engineered isolation, helps operators identify water-entry points, protect hydrocarbon flow, and restore sustainable well performance in mature and complex wells.
Equinor cites confined gas behind casing and calibration issues in investigation of Troll field well control incident.

The purpose of this paper is to apply multivariate statistical modeling in conjunction with geographic-information-systems (GIS) pattern-recognition work to the Eagle Ford. -
Production from the Bakken and Three Forks formations within the Williston basin is continuing to climb as a result of applied horizontal drilling and hydraulic fracturing.
-
Using large-scale hydraulic-fracturing experiments on tight shale outcrops, three dominant regions controlling stage production were identified.
-
An analysis of thousands of fracturing treatments in major plays in the United States provides insights into how fracture designs have changed over time.
-
Fiber optic pressure and temperature (P/T) sensing technology for multizone fracturing and production monitoring is enabled by a new feed-through (FT) technology that integrates the optical fiber within the multiple elastomer elements of a compact, swellable openhole packer system.
-
The demands for the fresh water used in many hydraulic fracturing operations are placing pressure on water sources in some regions of the United States. Because of the high volumes of water needed for fracturing and competing demands availability of fresh water has decreased and costs have grown.
-
This is the fifth article in a series covering water management in hydraulic fracturing in unconventional resources. The focus of this article is biological control. Additives to improve fracturing conditions can have negative effects on water treatment.
-
Statistics on well-integrity incidents are difficult to find in the literature. There are some examples of kick and blowout events, but normally they are scarce and focus on the number of incidents and their root causes.
-
The purpose of this work is to investigate typical fracture and collapse models with respect to accuracies in the input data.
-
Deepwater cementing becomes increasingly challenging as drilling operations move to greater water depths and more-remote locations.
