Drilling
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
This paper discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.
This edition highlights three offshore technology papers that address a common industry theme: how targeted engineering solutions can reduce uncertainty, shorten operations, and make technically constrained offshore well activities more executable.
-
Two years ago, as drillers approached the bottom of a deepwater well in the Lula field, they were stopped again and again by total drilling fluid losses. -
Dual-gradient drilling has long been described as the drilling method of the future for challenging offshore wells. Now, indications show it could start being used with some regularity.
-
The variables defining drill-bit performance cover a lot of ground. There is a lot of attention given to cutters studding diamond drill bits, but just as important are what is in the rest of the drillstring and the decisions made by the driller.
-
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.
-
A previous attempt to drill an exploration well in ultradeep water in the Gulf of Mexico (GOM) did not reach its objective.
