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.

Sand production is an unintended consequence of oil and gas production from unconsolidated and semi-consolidated reservoirs, causing damage to surface and subsurface well equipment and reducing the hydrocarbon productivity. -
This paper shares the engineering approach used to determine where and when sand control was needed in offshore Malaysia on the basis of geomechanical sand-free critical-drawdown-pressure evaluation for the selected well type, configuration, and completion.
-
Traditionally, sand-control equipment is used to prevent sand from entering the wellbore. An alternative is to produce solids with the well fluids and separate them at the surface.

This paper presents results from a nondestructive core-strength-index tester that is less destructive than the Schmidt hammer and less intrusive, easier, faster, and less expensive than the core scratch tester.
-
Europe and Australia have joined the US in expanding recoverable hydrocarbons from unconventional resources, and initial activities are on the rise elsewhere.
-
This paper sheds light on the nonlinear physics involved in the production of shale-gas reservoirs by improving the understanding of the complex relation between gas production, reservoir properties, and several treatment-design parameters.
-
Facilities sand management is tasked with the goal of ensuring sustained hydrocarbon production when particulate solids are present in well fluids, while minimizing the impact of the produced solids on surface equipment. How to do that?
-
Unconventional resources are often in good supply, but difficult and expensive to develop. To develop unconventional resources, technologies like hydraulic fracturing and horizontal drilling are key, and higher oil prices will help.
-
This is the third article of a series on water management for hydraulic fracturing in unconventional resources. This month, water treatment technologies are introduced, beginning with the removal of suspended solids by coagulation/flocculation and electrocoagulation for recycling flowback fluids.

Intelligent completion systems have the ability to monitor and optimize reservoir performance in real time without mechanical intervention.
