Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
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.
-
This paper describes the analysis of actual performance data for acid fracturing in a tight carbonate formation to investigate the ineffectiveness of the process. -
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.
-
The second phase of the project will analyze data gathered in Phase 1, with the goal of improving riser, wellhead, and conductor fatigue estimates.
