What is method of well completion?
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.
What is well completion and workover?
Well completion and workover. Journal Article Abbott, W; Patton, L – Pet. Eng. Int.; (United States) Completion or workover fluids (well servicing fluids) are those that are placed against the producing formation while well killing, cleaning out, plugging back, stimulating or perforating.
What is the main purpose of well completion?
Well completion is a series of steps–depending upon the completion method–performed after the drilling and casing phase, that enable to well to produce hydrocarbons. The primary goals are to stimulate the well to maximize production, and running tubing to enhance the well’s lifespan and ease of maintenance.
What is meant by well completion?
Well completion is defined as a single operation involving the installation of production casing and equipment in order to bring the well into production from one or more zones (Perrin, 1999).
What is drilling and completions?
The term “drilling” refers to the installation of the well bore including casing strings, cement and surface well control equipment. “Well completions” refers to various operations that may occur at a wellbore once the drilling operations are complete.
What are the well completion equipment?
Completion Equipment
- Hydraulics.
- Wellhead.
- Loss of Circulation.
- Water Injection.
- Surface Pressure.
- Reservoir Pressure.
- Fracture Pressure.
- Wellbore.
What is the difference between workover and well intervention?
Workover is an important part of the field development costs These oilfield maintenance operations aim at optimizing oil or gas production and keeping it to satisfactory levels. Well-intervention operations mean essential investments in the life of the well.
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 different types of wells?

What is liner in well completion?
Liner completions are similar to open hole completions in that casing must be set prior to drilling the producing interval. The advantage of a liner completion is that the drilling fluid system can be changed and a nondamaging fluid used to drill the pay interval.
What is well completion engineering?
Well completion includes all the steps needed to prepare a newly drilled well for production. It frequently begins with placement of casing adjacent to the producing formation and ends with installation of production tubing and surface hardware.
What is meant by well intervention?
Well intervention is the ability to safely enter a well with well control for the purpose of doing a number of tasks other than drilling. • Well intervention historically was done with drill rigs, with an 18-3/4” BOP and 21” marine riser as the only means of well access with well control.
