Content Completion - Definition Basic well completion sequence Pertinent completion concepts PSI completion Basic completion principles Completion elements Advanced completion technology
The Purpose of the Completion The well completion is the installation that enables production of fluids in a safe and efficient manner. Ideally, the lowest cost completion (considering both initial and operating costs) that meets the demands placed upon it for the well life.
Reservoir Management Tool The choice of completion concept is dictated by: The reservoir model and operator s drainage strategy. Horizontal wells Single zone/multiple zone Co-mingled production/flow control Pressure maintenance Reservoir properties. Open hole/cased hole completion Sand control measures Stimulation Artificial lift The physical and chemical qualities of the ROCK fluids. Completion metallurgy Elastomer qualities Deposits/Scale Chemical injection Other development considerations.
