Completions
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 study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.

The paper describes the operator’s first implementation of fishbone stimulation technology, establishing a precedent for other fishbone candidate wells. -
Offset well-pressure measurements in the Permian Basin are analyzed to evaluate if a fracturing job is overstimulated.
-
The authors use machine-learning methods combined with geomechanical, wellbore-trajectory, and completion data sets to develop models that predict which stages will experience difficulties during completion.

New Testing Facility Built To Prove Whether Natural-Gas Foam Is Shale Sector's Next Fracturing FluidA 6-year R&D project concludes with the completion of a technology kit designed to study how combining highly pressurized natural gas and water could be a holistic alternative to traditional hydraulic fracturing.
-
The qualification and first deployment of a low-solids, oil-based completion fluid that incorporates a newly developed, high-density brine as the internal phase to extend the density limit is discussed.
-
A pressure-monitoring technique using an offset sealed wellbore as a monitoring source has led to advancements in quantifying cluster efficiencies of hydraulic stimulations in real time.
