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.

A Gulf of Mexico case history is presented describing the successful delivery of two deep high-pressure high-rate-designed oil wells in an ultradeepwater environment. -
A new line of specialized polycrystalline-diamond-compact bits have been tested in a series of Bakken wells. The bits’ integrated design allowed significant increases in drilling rate and the number of plugs drilled.
