Injection Well (Secondary and Enhanced Oil Recovery (EOR)

As reservoir pressures decline, conventional production methods become less efficient. If determined to be economical, secondary (waterflood) and EOR (thermal, gas miscible, chemical) methods of production are used and continuous monitoring of the wellhead is common.

Continuous wellhead monitoring checks the ability of the reservoir to effectively handle the injected medium. Injection pressures that are too high could cause tubular fatigue and rupture problems. Also, injecting above the reservoir’s fracture gradient reduces the sweep efficiency of a waterflood and increases production overhead costs. This monitoring is achieved through the use of SOR level switches, level transmitters and pressure transmitters.
