Drilling
This guest editorial addresses the need for high-temperature directional drilling technologies as the number of rigs used to develop next-generation geothermal wells is set to rise in the coming years.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

A previous attempt to drill an exploration well in ultradeep water in the Gulf of Mexico (GOM) did not reach its objective. -
This paper describes the design, testing, installation, and performance of the first fully completed well using an intelligent inner completion inside an uncemented liner with openhole packers for zonal isolation.
-
This paper describes placement of horizontal wells in this kind of heterogeneous reservoir through an integrated approach.
-
The oil industry has always been innovative, even under adverse and challenging conditions imposed by the nature of upstream projects.
-
This paper presents a case history of a North Sea well in which managed-pressure drilling (MPD) was used as the enabling technology to drill, case, and cement the well.
-
This paper discusses the factors to be taken into account when designing cement jobs using fluids in turbulent flow and some of the overlooked benefits of using turbulent-flow design for mud removal.
-
This paper describes the first application of the 10¾-in. CV in a deep-well sour environment.
-
The most common method used for the placement of cement plugs is the balanced-plug method using drillpipe, tubing, or a combination of both.
-
Many good well-construction-technology papers came out last year, as well as a couple on older technologies that either had not been published earlier or had been released and were underappreciated.
-
This paper presents the results of a performance-improvement effort in extended-reach drilling (ERD) in three campaigns in the Huizhou HZ 25-4 oil field in the South China Sea.
