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.

Managed-pressure drilling has been associated as a technology used only on problematic wells and only as a last resort. However, when integrated at the beginning of operations as part of a comprehensive well plan, it becomes a performance-enhancing solution for any type of well classification, including development, directional, multilaterals, and horizontals. -
A team of engineers did something no one had done before: a full-scale fracturing test on the surface. The results surprised the fracturing experts involved.
-
The message from a single chart’s data from the first full-scale hydraulic fracturing surface test is simple: Far less proppant flows out of the first clusters passed in a stage than the last ones.

SponsoredFrac operators are continuously challenged by pressures to increase ROI and simultaneously decrease emissions. But is it really possible? New technology released in February from Catalyst Energy Services proves that it is possible. And the results are compelling.
-
Efforts to mitigate the potentially harmful effects of hydraulic fracturing have traditionally been divided along two fronts—those that primarily focus on protecting the environment and wildlife and those that focus on protecting humans and domestic animals. But it doesn’t have to be that way.
-
Induced seismicity put a stop to hydraulic fracturing in the UK, but rising natural gas prices might change that.
-
The authors develop a methodology that calculates the mechanical specific energy using real-time drillstring acceleration signals directly.
-
New research from Hess offers compelling evidence that two layers of tight rock can be treated as one and how passive wells can become oil producers.
-
High oil prices will mean more spending on workovers to eke out more oil and gas from older wells. The amount will depend on finding those willing and able to do that tricky work.

SponsoredAs world demand for energy increases, enhancing the efficiency of oil and gas production is key. Horizontal and multistage fracturing have made a huge difference in recovery. Fracturing fluids have played a key role in these gains—reducing costs and lessening fracture damage. Now fracturing fluids can be more sustainable as well, helping with your company’s ESG goals.
