Downhole ultraviolet system for mitigating lost circulation |
| abstract |
Method and systems for sealing a lost circulation zone of a subterranean well include extending a drill string into the subterranean well, the drill string having an ultraviolet system, an actuator, and a fluid flow path. The actuator is instructed to transmit an on signal to the ultraviolet system to switch the ultraviolet system to an on condition. In the on condition the ultraviolet system generates ultraviolet light directed towards the fluid flow path of the drill string. A loss circulation material is delivered into the fluid flow path of the drill string, the loss circulation material having an oligomer, a monomer, and a photo -initiator. The loss circulation material is exposed to the ultraviolet light to activate the loss circulation material. The loss circulation material is delivered to the lost circulation zone. |
