Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
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.
-
New report offers guidelines for pressure pumpers of the future. -
As wells across the US shale sector are brought back onto production, they may want to do so strategically to learn about the connectivity of their wells. One challenge will be in selecting a model that delivers the most insight.
-
Developed by the large shale producer, its new way to monitor interactions between horizontal wells is now available as a commercial software. The concept is considered a stepping stone toward real-time fracture design.
-
The new software enables high-resolution, real-time fracture-stage data to be shown on top of multiple previous stages to visualize optimized performance or to be tracked against an ideal preset stage.
-
Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run.
-
The papers summarized in this year’s feature demonstrate the application and versatility of coiled-tubing-based solutions to different phases of a well’s lifecycle, from exploration through production and, finally, to abandonment.
-
This paper describes a coiled tubing gas lift (CTGL) technique successfully used to restart production from two pilot wells in a mature field in Pakistan that had been shut in since 2015.
-
The complete paper discusses the systematic approach adopted by a service company to achieve the goal of safely abandoning wells offshore southwest Brazil with different completion types using light workover vessels.
-
The complete paper discusses a method of stimulating deep, high-temperature offshore wells by combining an efficient single-phase retarded acid (SPRA) system and an engineered, degradable, large-sized particulate and fiber-laden diverter (LPFD).
-
Several well-stimulation products and techniques have been seen to benefit well productivity from recent field trials and implementations in carbonate reservoirs, including simpler acid fluid systems, integrated work flows, and coiled-tubing bottomhole assemblies.
