ABSTRACT:

Pressure leaks in oilfield equipment can lead to inoperable systems, casing pressure, environmental pollution, loss of production and blowouts. T he traditional method of curing pressure leaks has been a risky and expensive well intervention operation. A separate-but intangible-cost of such well intervention operations is the risk associated with such operations including personnel injury, environmental damage, wellbore damage and loss of production. What is needed is a cost-effective method of repairing wellhead and downhole leaks in-situ without the need of mobilizing expensive and risky rig or wireline operations. This paper focuses on a program of wellhead leaks that were treated in Kazakhstan.
