hOW many types of well completion are there?
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 are the components of well completion?
A well completion consists of two parts, the sand-face completion that provides the interface between the reservoir rock and the wellbore, and the upper completion, comprising equipment installed within the last casing string to control and monitor the well flow and ensure well safety.
What is well completion equipment?
Completion equipment are those equipment which are used to bring an oil well to the completion state so that first test production and later on commercial production can be started from it.
What are the types of completion?
Types of completions
- Completions can be divided into three categories: open hole completions, liner completions, and perforated casing completions.
- Open hole completions were originally used in the early days of the petroleum industry when most wells were drilled with cable tools.
What does a completion engineer do?
Completions engineers decide the best way to finish building wells so that oil or gas will flow up from underground. They oversee work to complete the building of wellsa project that might involve the use of tubing, hydraulic fracturing, or pressure-control techniques.
What happens after the well is drilled?
After a well is drilled, a water pump is installed to draw water from the well into your property’s water system.In most cases we recommend that a pump test be performed to clear the water, establish an accurate flow rate and drawdown test.
What is completion tubing?
A completion that utilizes coiled tubing as the production conduit, or as a means of conveying and installing completion equipment or components. Since the coiled tubing string is continuous, problems associated with connections are avoided.
What is conventional well completion?
Conventional completions Casing flow: means that the producing fluid flow has only one path to the surface through the casing. Casing and tubing flow: means that there is tubing within the casing that allows fluid to reach the surface. This tubing can be used as a kill string for chemical injection.
What is cementing in well completion?
Well cementing is the process of introducing cement to the annular space between the well-bore and casing or to the annular space between two successive casing strings. Personnel who conduct this job are called “Cementers”.
What is the difference between upper and lower completions?
Depending on the place where the completion is made, oil and gas well completions are divided into lower completion or downhole completion, and upper completion. The lower completion connects the oil and gas formation with the wellbore. The upper completion is the link between the lower completion and the surface.
How does well completion work?
Well completion incorporates the steps taken to transform a drilled well into a producing one. These steps include casing, cementing, perforating, gravel packing and installing a production tree. The first step in completing a well is to case the hole.
