A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.
The authors reach conclusions that the industry should define a standard testing method to improve swelling performance, including validation of repeatability, to complement existing guidelines.
-
This study introduces a detailed model to capture the physics and chemistry of acid flow in complex horizontal wells completed in carbonate formations. -
The authors of this paper describe a project in which far-field diverters were pumped to mitigate wellbore sanding and production loss in existing parent wells.
-
This paper describes the application of an underbalanced coiled tubing technology in tight sandstones, using an integrative approach that incorporates petrophysical, geophysical, and reservoir engineering data.
-
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.
-
Engineers desperately need an alternative to acid placement through pipe, coiled tubing, or bullheading. For example, propellants have been around for years; however, their performance has not quite met the hype. Nevertheless, several case histories have been authored to suggest their efficacy; historically, some treatments have even been wildly successful.

Years in the making, the program sponsored by the US Department of Energy is celebrating its latest geothermal energy breakthrough in southwestern Utah.
-
Operators are turning the tide on the Lower Tertiary trend with increasingly large stimulations that are also pushing the limits of offshore technology.
-
Matthew Bryant has spent years trying to convince engineers that the API proppant testing standard has significant limitations. And he may well be right.
-
This paper presents laboratory testing and application of a resin-cement system designed to be placed as a tail slurry to provide enhanced mechanical properties compared with a conventional slurry.
-
This paper describes a foamed cement solution designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta.
