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 cementing services market size in the US is expected to drop 50% year-on-year from 2019. The significant drop in Permian Basin activity will account for 40% of the total market size reduction. -
The complete paper presents a discussion of the use of intelligent well completion in Santos Basin Presalt Cluster wells.

Faster drilling speeds have become one of the major obsessions of the shale sector in recent years. But since completions represent up to 70% of a new well’s cost, maybe this side of the business needs more attention now.
-
The room for error and cost overruns just got a lot smaller with the escalating need to make operations more efficient and leaner with fewer resources and investors continuing to prioritize ESG alongside profitability.

While many shale producers are racing to cut costs by removing crews from the field, ExxonMobil and Chevron stood out as maintaining large numbers of fracturing crews.

Machine learning can provide accurate prediction of annular pressure buildup, first-year oil production, and (in conjunction with novel casing accessories) the time and location of water breakthrough along a lateral wellbore.
-
Proper lateral and vertical well spacing is critical for efficient development of unconventional reservoirs. Much research has focused on lateral well spacing but little on vertical spacing, which is challenging for stacked-bench plays such as the Permian Basin.

The complete paper describes piloting the collection and analysis of distributed temperature and acoustic sensing (DTS and DAS, respectively) data to characterize flow-control-device (FCD) performance and help improve understanding of steam-assisted gravity drainage (SAGD) inflow distribution.
