Well Completion is the process of making a drilled well ready for production. This involves installing various equipment and materials to ensure that oil or gas can flow efficiently from the underground reservoir to the surface. Key components include casing, which supports the well structure, and perforations that allow hydrocarbons to enter the well. After drilling, Well Completion also includes testing the well to assess its productivity and determining the best methods for extraction. This phase is crucial for maximizing the well's output while ensuring safety and environmental protection throughout the production process.
