Completion systems are the components necessary to complete a well after it is drilled and prepare it for production. There are a variety of completion options available to oil and gas operators. Cased-hole completion systems, for example, vary from relatively simple single-zone low-pressure/low-temperature (LP/LT) designs to complex high-pressure/high-temperature (HP/HT) applications that are commonly found in deepwater. Cased-hole completion involves running casing or a liner down through the production zone, and cementing it in place. A good cement job is the primary barrier for effective zonal isolation and is the standard industry method to protect the wellbore from unwanted and dangerous influxes of formation fluids, solids and gases.
