Unconventional/complex reservoirs

The Permian Basin operator said the purchase translates to more than a decade of additional inventory.

In this first part of a two-part series, we look at how the artificial-lift sector has adapted to producing unconventional resources. The second part of the series to publish in November will crack open the lift toolbox to take a deeper look at the techniques and technologies under development or new to the market.

The paper presents successful field tests designed to decrease electrical-submersible-pump cooling rates by inducing controlled deadheads rather than shutting down the pumps.

Founded by former analytics experts for a large US independent, Xecta Digital Labs is proposing a new analysis method for horizontal wells. Adopting it means turning the page on some old habits.

This paper presents agile technologies that integrate data management, data-quality assessment, and predictive machine learning to maximize asset value using underused legacy core data.

The authors write that child-well performance increases with spacing and decreases with infill timing and that the parent cumulative production at child-well completion is an effective indicator of child-well performance.

The paper presents results of single-phase and multiphase electrical-submersible-pump tests as well as operation data, lessons learned, and failure examples gathered over 10 years of operation in a highly viscous offshore oilfield.

Injecting gas plus water proved more effective and less costly than gas-only injection in the Bakken.

Digital systems are helping ensure US independent Diversified Energy continues to grow and optimize production from its mature assets.

The Sydney-based company announced it will also seek to exit all of its upstream permits with the exception of its major LNG joint venture.
