Well completion techniques are methods used to prepare a drilled well for production. These techniques involve installing equipment and systems that allow for the efficient extraction of resources, such as oil or natural gas, from underground reservoirs. Common methods include the use of casing, which protects the wellbore, and perforation, which creates openings in the casing to allow fluids to flow into the well. Another important aspect of well completion is stimulation, which enhances the flow of resources by increasing permeability in the surrounding rock. Techniques like hydraulic fracturing or acidizing are often employed to improve production rates. Overall, these techniques are crucial for maximizing the efficiency and safety of resource extraction.
