Definition - What does Scale Inhibitor mean?
Scale Inhibitor is a chemical which is continuously injected into the production tubular so as to control or prevent the deposition of scale. Scaling in oil and gas wells is a problem which should to be dealt with in order to maintain the asset integrity of the well. The chemical also protects well casings, valves, pumps, downhole and completion equipment from scaling.
Petropedia explains Scale Inhibitor
In oil and gas wells, scaling occurs due to the production of water from hydrocarbon producing wells. This leads to the formation of inorganic scales on the production conduit and other associated equipment. Scaling can cause loss in production, well fatigue and ultimately abandonment of the well. Scale Inhibitors help in maintaining cost-effective asset integrity and prolong the life of the well. The following are some of the benefits of using scale inhibitors:
- Mechanical and chemical cleanout of well can be reduced thereby reducing the operation downtime.
- They increase the life of the well and associated machinery.
- Flow stream capacities are maintained.
