Well completion is the final phase of preparing an oil or gas well for production. It involves various processes and techniques to enable the extraction of hydrocarbons from the reservoir. Activities include casing, cementing, perforation, installing tubing, and using technologies to optimize production and ensure well integrity. The goal is to establish a secure and efficient connection between the reservoir and surface facilities.

Well workover involves maintenance, repair, or enhancement operations on an existing oil or gas well to improve productivity. It addresses issues like declining production, equipment malfunctions, or wellbore damage. Activities include tubing replacement, wellbore repairs, reservoir stimulation, and other measures to optimize performance and extend the well’s life. The goal is to maximize production potential and ensure efficient operations.
