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 authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design. -
The authors describe a casing-leak-repair alternative to allow continued hydraulic fracturing of an unconventional formation.
-
The authors describe coiled tubing operations that used a riser on a monohulled vessel already performing riserless interventions.
-
The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.
-
In this paper, a comparison is presented of the range of production outcomes for Clair Phase 1 and Clair Ridge, including the potential downsides of relying on natural fractures.
-
Fracture monitoring to optimize fluid volumes and designs remains a critical area of development. Research is ongoing with the focus on combining different monitoring technologies including tracers, fiber optics, downhole cameras, and microseismic monitoring.
-
This paper presents a novel mathematical model for design and evaluation of fluoroboric acid treatments that takes into account the chemical kinetics and equilibrium aspects of important reactions and fluid flow inside the reservoir rock.
-
When there are two ways to measure something, and they offer significantly different numbers, which do you use?
-
The second phase of the project will analyze data gathered in Phase 1, with the goal of improving riser, wellhead, and conductor fatigue estimates.
