Reservoir

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 authors describe the process of building multiple scenario-based models to optimize development planning in preparation for the upcoming production phase of the Ichthys field offshore Australia.

The authors demonstrate how artificial intelligence and machine learning can help build a purely data-driven reservoir simulation model that successfully history matches dynamic variables for wells in a complex offshore field and that can be used for production forecasting.

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 paper describes an end-to-end deep surrogate model capable of modeling field and individual-well production rates given arbitrary sequences of actions.

The latest success for the ExxonMobil-led consortium is also adding drillships to support a 15-well campaign in the Stabroek Block.

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