System and method for safely conducting explosive operations in a formation

摘要

Method and system that permits explosive operations to be conducted concurrently with drilling and other wellsite operations involving an electrical top drive mechanism or other components that utilize electricity are disclosed. A platform is placed at a location where subterranean operations are to be performed. A first well bore is drilled in a formation using drilling equipment on the platform by activating a top drive. Concurrently with drilling the first well bore, a perforating operation is performed in a second well bore extending from the platform. The perforating operation is performed using a perforating gun that comprises at least one of an electric isolator and an explosive isolator. The perforating gun is activated when the perforating gun reaches a safe depth.

1. A method for concurrent performance of a drilling operation and a perforating operation comprising:
placing a platform at a location where subterranean operations are to be performed; drilling a first well bore in a formation using drilling equipment on the platform,
wherein drilling the first well bore comprises activating a top drive; performing a perforating operation in a second well bore extending from the platform,
wherein the perforating operation in the second well bore is performed concurrently with drilling the first well bore,wherein the perforating operation is performed using a perforating gun,wherein the perforating gun comprises at least one of an electric isolator and an explosive isolator, andwherein the explosive isolator is operable to substantially isolate the electrical initiator from the explosive,wherein the electric isolator is operable to substantially isolate the electrical initiator from the platform, andwherein the perforating gun is activated when the perforating gun reaches a safe depth, wherein activating the perforating gun comprises receiving one or more measurements within a predetermined time when the perforating gun reaches the safe depth, determining if one or more predetermined criteria have been met based, at least in part, on the one or more measurements, sending a sequence of commands to the perforating gun, receiving a validation of the sequence of commands and arming the perforating gun based at least in part on at least one of the validation and the determination.
