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.
More than 150 researchers will work on the Libra Rocks project, which aims to unlock insights that could improve recovery and reservoir management in one of Brazil’s largest offshore oil fields.

The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior. -
Though shelved by low oil prices, the plan to execute the largest enhanced oil recovery program of its kind offers insights into what it may take for the shale sector to escape pilot mode and scale up gas huff ’n’ puff operations.

Automated image-processing algorithms can improve the quality and speed in classifying the morphology of heterogeneous carbonate rock. Several commercial products have produced petrophysical properties from 2D images and, to a lesser extent, from 3D images.

With reduced new unconventional well activity, practices such as frac-hit mitigation—pressurization of parent wells during child-well fracture stimulation—have become increasingly important to reduce parent-well proppant cleanouts as well as to maximize production from both parent and child wells.
-
This latest find means the offshore driller has averaged at least three new discoveries each year since it began drilling offshore Guyana where it plans to recover up to 8 billion barrels of crude.

Unconventional producers around the world have been hamstrung by expensive and cumbersome options when it comes to obtaining reservoir data. Among the latest ways to break past these barriers is a new method developed by Canadian researchers and field tested in Australia’s unconventional frontier.
-
The source of gummy, damaging polymer gunk that has flowed from Oklahoma oil wells is becoming clear, and one of the lessons learned is that shale plays require petroleum engineers to learn more about chemistry.
-
Before the giant Johan Sverdrup field had produced even one barrel of oil, operator Equinor and its license partners set a recovery ambition of greater than 70% for the field.

Decline-curve analysis is one of the more widely used forms of data analysis that evaluates well behavior and forecasts production and reserves. This paper presents technologies that apply DCA methods to wells in an unbiased, systematic, intelligent, and automated fashion.

While the ongoing trends in data science and engineering analytics are going to show more benefits in lowering production costs and increasing efficiencies, the well-established reservoir and production engineering disciplines will continue to be critical for reservoir performance improvements.
