This guest editorial from the Center for Injection and Seismicity Research (CISR) at The University of Texas at Austin details the emerging risks posed by injection in Texas and what steps might be taken to mitigate them. -
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 paper presents the development of an advanced simulation tool aimed at providing a better understanding of the complex fluid-displacement phenomena present in well-cementing processes.
-
This paper examines the effects of cement voids and microannuli on the collapse resistance of pipe/cement/pipe systems with void angles ranging from 0º to 70º.
-
An investigative study examines the use of creeping shale formations as a more durable alternative to conventional cement barriers in carbon dioxide storage wells, potentially enabling safer long-term underground carbon storage.
-
SponsoredUnwanted water production can erode well performance and asset economics if left unmanaged. Interwell’s precision water shutoff approach, grounded in diagnostics and engineered isolation, helps operators identify water-entry points, protect hydrocarbon flow, and restore sustainable well performance in mature and complex wells.
-
SponsoredSince 1997, intelligent completions have transformed reservoir management, but adoption remains limited due to perceived complexity. The industry reached a pivotal moment with the development of next-generation technologies that address longstanding challenges and offer simpler operation solutions.
-
This paper expands the understanding of geopolymer/microsphere interactions and presents design considerations for alternative cementing materials under low-temperature regimes.
-
This paper addresses the deployment of an external protective coating with a rough surface profile in wells identified as susceptible to common cementing issues.
-
This paper provides examples for planning and execution of primary and remedial managed pressure cementing in deepwater drilling operations.
