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.

This paper discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation. -
Advanced horizontal drilling, multistage hydraulic fracturing, and other technologies have helped make the Vaca Muerta shale oil and gas resource economically viable.

This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations.
-
This study aims to investigate the efficacy and feasibility of cryogenic-fracturing technology in enhancing the permeability of unconventional-reservoir-rock analogs.
-
Tight formations are candidates for hydraulic fracturing as the default. However, the solubility of carbonate by various chemicals provides opportunities to extend the well drainage radius effectively without the intensive equipment, material, and infrastructure demand of hydraulic fracturing.

Significant production gains are being made with hydraulicly fractured wells using diversion to stimulate a higher percentage of the perforations.
-
There is increasing interest in drilling the Austin Chalk formation, with hopes that the latest unconventional development methods can deliver a boom in a play that has seen several over a 90-year history.
