Completions
This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.
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.

Many different completion techniques, such as vertical-well multiseam completions and multiple lateral wellbores drilled into a single coal seam, have been used to develop coalbed methane (CBM) reservoirs. -
In the southern North Sea, many fields suffer from declining gas production because of reservoir-pressure depletion and associated liquid loading.
-
There has been remarkable growth in the coiled-tubing industry in North America, resulting largely from the shale revolution. This growth attracted numerous new players into the industry, in addition to the capacity additions made by the existing service providers.
-
Horizontal wellbores typically encounter inefficiencies caused by friction during drilling and completion operations.
-
Sticking the coiled tubing (CT) is a major operational risk when performing a well intervention with CT. Stuck-pipe incidents often result in considerable production delay or, in the worst case, loss of the well.
-
Novel multizone stimulation technologies have enabled the development of tight resources that previously could not be developed economically and have enabled optimization of production resources distributed over thick gross intervals.
-
As oil companies have moved to more-marginal reservoir targets, application of conventional techniques has often yielded disappointing results, and tighter zones are often abandoned for more-promising target intervals.
-
In the Danish central graben, tight chalk reservoirs have been developed successfully through drilling, completion, and stimulation of long horizontal wells.
-
This is the first of several articles on the subject of water management for unconventional hydraulic fracturing. This article outlines the critical issues and outlines development of a strategy for treatment of flowback fluids.

This paper describes an all-in-one system that combines nodal-analysis and numerical-simulation models to calculate the effect of intelligent-completion components—such as swell packers, internal control valves, and inflow-control devices—on lateral production profiles.
