Unconventional/complex reservoirs
Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.
The US supermajor is using one of its lowest-value hydrocarbon products to generate double-digit production increases in its most prolific US asset.
The transaction adds 267,000 net acres and nearly 140,000 BOE/D from Vital Energy, lifting Crescent into the top 10 largest US independents.

Overcoming numerous regulatory hurdles, Cuadrilla Resources is pressing ahead with its plans to fracture a well in the UK for the first time since 2011. -
Shale gas is one of least sustainable options for producing electricity, according to new research from The University of Manchester, which considered environmental, economic, and social sustainability factors.
-
The objective of the complete paper is to present an integrated work flow that can be used to build P90, mean, and P10 type wells, which represent the range of potential outcomes for the geologic subset in an unconventional resource play.
-
After a drop in drilling activity in recent years, the Haynesville shale has become a hot area for natural gas production in the US, and companies are looking to bolster their positions in the area.
-
Natural gas producers should remain happy campers for the foreseeable future; they are supplying an increasing long-term demand at an increasingly stable international market price.
-
The primary objective of this study is to address all known causes of productivity declines in unconventional shale gas formations with horizontal multifractured wells and to develop a fully coupled geomechanical/flow simulation model to simulate these production conditions.

Currently, there are few studies on smart waterflooding in tight and very tight oil reservoirs. This work examines smart-waterflood opportunities in such reservoirs.
-
Previous studies demonstrate that Montney rock samples present a dual-wettability pore network. Recovery of the oil retained in the small hydrophobic pores is uniquely challenging.
-
While enhancing oil production from multizone, hydraulically fractured completions in tight reservoirs is not straightforward, recent studies have shown that applications such as gas injection and waterflooding have the potential to create significant improvement in oil recovery.

This paper presents the performance results from one of the waterflood pilots in the Viewfield Bakken.
