Open hole completion means that the oil reservoir is completely exposed during completion of a straight or horizontal well. There are two types of procedures for open hole completion. 1. After drilling to the top of the oil reservoir, the intermediate casing is run in and the well is cemented.

What is wellbore 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 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 open hole wireline?

Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation.

What is a wellhead in oil and gas?

A wellhead is an equipment installed at the surface of a completed oil or a gas well that provides a structural and pressure containing interface for the drilling and production equipment.

How do wellheads work?

Simply put, a wellhead is a system of spools, valves, and assorted adapters that used to provide pressure control of a production well. Its primary purpose is to provide a suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.

What is upper and lower completion?

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.

What is completion drill?

From Wikipedia, the free encyclopedia. Well completion is the process of making a well ready for production (or injection) after drilling operations.
