Unconventional/complex reservoirs
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
This year’s selected papers showcase meaningful advances across condensate‑rich tight gas, tight sandstones, and coalbed methane reservoirs, each contributing new tools for improving predictability and field-development efficiency.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.

Founded by former analytics experts for a large US independent, Xecta Digital Labs is proposing a new analysis method for horizontal wells. Adopting it means turning the page on some old habits. -
This paper presents agile technologies that integrate data management, data-quality assessment, and predictive machine learning to maximize asset value using underused legacy core data.
-
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.
