Abstract
The present disclosure describes methods and systems for downhole well integrity reconstruction in a hydrocarbon reservoir. One method for downhole well integrity reconstruction in a hydrocarbon reservoir includes: positioning, a laser head at a first subterranean location, wherein the laser head is attached to a tubular inside of a wellbore; directing, by the laser head, a laser beam towards a leak on the wellbore; and sealing the leak using the laser beam.
Claims6
An in-situ 3-dimensional (3D) laser head, comprising:
- a reflector that is attached to a tubular inside of a wellbore engaged in a drilling operation;
- two protectors attached to the tubular inside of the wellbore;
- and
- a focused lens positioned between the two protectors, wherein the reflector is configured to reflect a laser beam towards the focused lens, and the reflector and the focused lens are vertically displaceable and rotatable to direct the laser beam, as a divergent beam, towards a cased hole leak on the wellbore, and wherein the laser beam is configured to generate a corresponding level of temperature at the cased hole leak according to a rock type of a formation at the cased hole leak.
