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.

An ongoing research project started nearly 3 years ago by the US Department of Energy’s National Energy Technology Laboratory (NETL) is shedding new light on what really happens to foamed cement as it is pumped deep down offshore wells during completions.

A scientist hired by federal regulators to look for ways to reduce the risk of well blowouts said it is time for the oil and gas industry to treat kicks taken while drilling the same way doctors treat heart attacks.

The United States’ liquids-rich shale experience has been dominated by three major plays: the Eagle Ford Shale in south Texas, the Permian Basin in west Texas, and the Bakken Shale that straddles North Dakota and Montana.

Making hole has become a more difficult and complex operation as operators move into untapped horizons, especially deepwater and unconventional fields.
-
In response to the 2010 Deepwater Horizon incident that claimed the lives of 11 men and led to the worst oil spill in United States history, the offshore industry devised new technologies and methods that would allow for a quicker response in the US Gulf of Mexico.

The ultimate performance of fractured wells in tight reservoirs is affected severely by the interfering effects inside the fracture and interfractures.
-
A well drilled and completed in a marginal field offshore India produced only gas until the oil-bearing sands were perforated and the well was put on commingled-oil-and-gas production.
-
Drilling long horizontal wellbores and completing wells with multistage fracturing are common practices in shale-play development.
