Unconventional/complex reservoirs

CNPC’s record-breaking 11,100-m exploration borehole in the Taklamakan Desert promises to unlock the science of producing oil and gas trapped in the world’s deepest reservoirs.

This study catalogs global gas/oil ratio data to identify currently produced light crude oils that could be rendered carbon neutral through the direct-air-capture mechanism.

As the demand for energy continues to increase, so does the sociopolitical demand that these resources be produced in a sustainable way. This reflective thought has defined this month’s selection of technical papers, each speaking to a different facet of this feature’s theme: unconventional reservoir development for a sustainable energy transition.

This paper describes natural fractures and their effect on hydrocarbon productivity in the Vaca Muerta shale formation.

The objective of this study was to establish an efficient optimization work flow to improve vertical and areal sweep in a sour-gas injection operation, thereby maximizing recovery under operation constraints.

The objective of this paper is to present a fundamentals-based model of three-phase flow consistent with observation that avoids the pitfalls of conventional models such as Stone II or Baker’s three-phase permeability models.

The authors of this paper describe a solution using machine-learning techniques to predict sandstone distribution and, to some extent, automate the process of optimizing well placement.

DJ Basin player enters the Permian Basin with a pair of asset purchases from private-equity vehicles.

The US-based drilling contractor and well completions company will combine to form the second-biggest service company in North America.

A concurrent deal to sell off some of the acquired assets to Northern Oil and Gas will effectively lower the acquisition cost to $1 billion.
