In the high-risk, high-reward world of oil and gas production, closing the tap on a well is half the battle. The actual magic occurs during oilfield completions, the crucial period when a newly drilled well is turned into a productive asset that can produce oil or gas efficiently and without harming workers, the environment or the surrounding community.

What are oilfield completions?

Oilfield completions are the engineering and operational processes completed between the drilling of a well and the production of oil or gas.That includes the drilling of the well, placement of production equipment and being able to extract the hydrocarbons from the reservoir to the surface in an efficient manner. Even if you have a perfectly drilled well, failure to properly complete a well can still result in downtime and high expenses later on.

Key completion techniques

There are a number of options for completion, and these vary depending upon formation conditions and production goals:

Open Hole Completions: The reservoir is not cased in the production zone, which is suitable for horizontal or naturally fractured formations.

Cased Hole Completions: Steel casing is run and cemented and the well is perforated to manage flow and increase productivity.

Methods of Stimulation: Permeability is increased and flow from tight formations is improved by methods which increase permeability, such as hydraulic fracturing or acidifying.

Why it matters

The completions art is a combination of the science of formations, the technology of drilling and the economic planning of production. The optimal completion design lowers costs, extends well life, increases recovery and lessens environmental and safety related risk. Today s energy world Smart completions also include real-time monitoring and data Analytics to maxima performance from Day 1.

Oilfield completions: Where invention meets practical application. By linking drilling to production, they make sure that energy assets are not only foundd but used in an environmentally friendly and efficient manner.
