What are the types of well completion?

Completions can be divided into three categories: open hole completions, liner completions, and perforated casing completions. In most wells, conventional single perforated casing completions are used; however, multiple, alternate, or slim hole completions may be used under certain conditions.

What is meant by well completion?

Well completion is the process of making a well ready for production (or injection) after drilling operations. After a well has been drilled, should the drilling fluids be removed, the well would eventually close in upon itself.

What is completion oil and gas?

A generic term used to describe the events and equipment necessary to bring a wellbore into production once drilling operations have been concluded, including but not limited to the assembly of downhole tubulars and equipment required to enable safe and efficient production from an oil or gas well.

What do you need to know about dual well completion?

Dual Well Completion In a dual well completion, a single wellbore has tubulars, packers and other tools to enable production from two different zones. Generally, two tubing strings are used to provide necessary level of control, safety and segregation between fluids from the two different zones in a single wellbore.

What is the definition of a completion well?

A single completion well corresponds to a single zone of fluids from a sinle wellbore. A single tubing string installation to encloses the tubulars, packers, and other tools which enable the flow path for crude oil and natural gases.

What are the different types of multiple completions?

Multiple completions include the tubing-casing dual, dual tubing strings, and the typical triple completion consisting of three tubing strings. Figures 4 and 5 illustrate these multiple completions. The more complex the completion, the more trouble one can expect in both completion operations and in subsequent workover operations.

What are the different types of completions on an AAPG?

Multiple completions include the tubing-casing dual, dual tubing strings, and the typical triple completion consisting of three tubing strings. Figures 4 and 5 illustrate these multiple completions.
