摘要 |
<p>A tubular patch system has been invented for patching operations which, in one aspect, is useful as a "through tubing" tubular patch system and has a body and a series of selectively expandable members which, once having passed through a tubular of a first diameter, are expandable in a tubular of a second diameter larger than the first diameter and then operable to expand a liner patch to seal a leak in the tubular of the second diameter. Such a system may be used in a tubular disposed within a wellbore or in a tubular on the earth surface.</p> |
