Patent ID: 8869914

Claim:
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.
