Recent news headlines about gas storage incidents highlight the fact that it is not only oil and gas producing wells that need continuous real-time integrity monitoring to avoid catastrophic leaks.
Operators of underground gas storage (UGS) wells have to be confident that they have complete control over their integrity. The well tubing, well casing, casing cement bond, sealing elements in the wells, packers, wellhead seals and valves all present opportunities for leakage. Without control of each and every one of these components, the whole well loses integrity.
Should a breach occur, with risk of a leak or major blow out, the storage facility not only poses significant risks to health, safety and the environment, it is quite literally leaking profits. Well integrity management provides further operational cost-reduction by optimizing the scheduling of well activities like maintenance and inspections as well as real-time risk assessment for activity prioritization.
