Well completion is the process of preparing a drilled oil or gas well for production. This involves installing various equipment, such as casing and tubing, to ensure that the well can safely and efficiently extract resources from underground reservoirs. The completion process also includes perforating the well to allow oil or gas to flow into the wellbore. After the initial drilling, well completion techniques can vary based on the geological conditions and the type of resource being extracted. Proper completion is crucial for maximizing production and minimizing environmental impact, ensuring that the well operates effectively over its lifespan.
