Unconventional/complex reservoirs
This work applies fuzzy logic, a well-established artificial-intelligence technique, to quantitatively assess connectivity between injectors and producers in a giant presalt field in the Santos Basin of Brazil.
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives.
With a strong presence across US shale in the Bakken, Anadarko Basin, Powder River Basin, and the Permian, Continental Resources is expanding into Argentina’s Vaca Muerta shale as the privately held E&P giant pursues international growth.
-
Thousands of horizontal wells that had been drilled but uncompleted (DUCs) offered a way to maintain production without the cost of drilling more wells, but that resource is finally running low. -
The third quarter has so far not seen any mergers and acquisitions in the shale business that top $1 billion.
-
The paper aims to determine the mechanisms of fracturing interference with multiwell pads in shale gas reservoirs and evaluate the effect of interwell fracturing interference on production.
-
This paper reviews innovations and technologies used to make the Atlanta field in the Santos Basin a successful case of heavy-oil production in ultradeep water.
-
The authors write that cyclic gas injection enhanced oil recovery for Eagle Ford volatile oil can yield substantial increases in estimated ultimate recovery.
-
A fast-moving pressure pulse is the priority of a research and development initiative that, if successful, will result in a new diagnostic technology for horizontal wells in tight 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.
