High power laser workover and completion tools and systems

摘要

Workover and completion systems, devices and methods for utilizing 10 kW or more laser energy transmitted deep into the earth with the suppression of associated nonlinear phenomena. Systems and devices for the laser workover and completion of a borehole in the earth. These systems and devices can deliver high power laser energy down a deep borehole, while maintaining the high power to perform laser workover and completion operations in such boreholes deep within the earth.

主权项

1. A high power laser workover and completion system for providing high power laser energy to a location in a wellbore in a precise and controlled manner to perform a laser workover and completion operation in the wellbore, the system comprising:
a. a high power laser source capable of providing a high power laser beam having a power of at least about 15 kW, and a beam parameter product of about less than 100 mm milliard; a chiller operably associated with the high power laser source; b. a means for transmitting the laser beam from the high power laser source to a predetermined location in the wellbore for performing a workover and completion operation; and, c. the transmitting means optically associated with a means for suppressing nonlinear scattering phenomena arising from the transmission of the laser beam having a power of at least about 15 kW; and, d. the transmitting means optically and mechanically associated with a high power laser workover and completion bottom hole assembly; e. whereby, the high power laser beam is delivered to the predetermined location in the wellbore with sufficient power to perform the laser workover and completion operation.
