Unconventional/complex reservoirs

This paper describes an artificial-lift technology, a subsurface compressor system, that simultaneously removes liquids, increases gas production, and improves recoverable reserves in gas wells.

A 2-year study of a formation used for saltwater disposal in the Bakken may hold promise of decreasing the pressurization of the formation and increasing the reuse of the briny produced water.

Applications of particular interest are those addressing challenging well-production needs such as reducing or eliminating liquid loading in gas wells; restimulating existing, underperforming wells, including as an alternative to new well drilling and completion; and remediating water blocking and condensate buildup, both of which can severely impair production from g…

The authors of this paper propose a new chemical treatment for efficient remediation of water- or hydrocarbon-phase-trapping damage in low-permeability porous media.

The implementation of fishbone stimulation helped to more than double estimated well productivity and tripled the production rate in a tight carbonate reservoir well compared with conventional stimulation during initial testing.

When fracturing, simply shooting all the perforations at the same spot in the casing can offer increased production at a low cost.

The all-stock transaction is expected to bolster the newly created operator's production profile to around 160,000 BOE/D.

Oil isn’t going away, but that misses the fact that a demand plateau will structurally change the industry for people and companies in the most geologically mature areas, especially the United States.

A lot has been learned about shale, but those working to eke out oil from that ultratight rock still extract more value from data than physics.

Physics-based simulations plus machine-learning exercises are yielding a more comprehensive look at production volumes from unconventional assets.
