A method includes collecting seismic survey data and processing the seismic survey data to identify subterranean conduit coordinates. The method also includes performing a conduit plugging operations using the identified subterranean conduit coordinates. A related system includes at least one seismic source and at least one seismic receiver to collect seismic survey data in response to at least one shot fired by the at least one seismic source. The system also includes a processing unit in communication with the at least one seismic receiver. The processing unit analyzes the collected seismic survey data to identify subterranean conduit coordinates for use with conduit plugging operations.

Methods and systems for identifying and plugging subterranean conduits

In a subsea drilling operation, a riser isolation tool may be installed inside a marine riser between the subsea wellhead and the rig floor to provide a conduit having a higher pressure rating than the original riser itself. In some embodiments, the riser isolation tool includes a tubular body and, extending therefrom, a seal stinger sized to be slidably received in a receptacle seated in the wellhead. Additional apparatus, systems, and methods are disclosed.
