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.

The authors write that child-well performance increases with spacing and decreases with infill timing and that the parent cumulative production at child-well completion is an effective indicator of child-well performance. -
The paper presents results of single-phase and multiphase electrical-submersible-pump tests as well as operation data, lessons learned, and failure examples gathered over 10 years of operation in a highly viscous offshore oilfield.

Injecting gas plus water proved more effective and less costly than gas-only injection in the Bakken.
-
Digital systems are helping ensure US independent Diversified Energy continues to grow and optimize production from its mature assets.
-
The Sydney-based company announced it will also seek to exit all of its upstream permits with the exception of its major LNG joint venture.
-
ADNOC awarded a new round of contracts to international service companies, intending to apply directional drilling and LWD to boost production by getting a better assessment of its reservoirs.
-
When Occidental Resources switched to bigger fracture designs to produce more oil, it produced more water as well. Based on research done since, they cannot have one without the other, and at the oil prices recently seen, that’s OK.
-
The authors of this paper use a pattern-review technique in a complex brownfield as a tool to understand reservoir connectivity and dynamic fluid movements across the field.
-
The authors of this paper describe a fiber-optic diagnostic method based on Rayleigh frequency shift that provides new insights about the characteristics of the near-wellbore region during production.

Glynn Williams, CEO of Silixa, offers his take on the role fiber-optic technology will play in the rise of CO2 storage and on the firm’s progress in the tight-rock sector.
