Summary
A case study of using migration of duplex waves to trace zones of near-vertical fracturing in coal formation is described. As a rule, coal-bed methane traps are connected with these zones, however, identification and tracing of them based on the standard seismic exploration techniques are practically impossible. It is shown that the joint analysis of structural interpretation and seismic facies investigation data and of the results of duplex wave migration improves efficiency of coalbed methane prediction. The work has been carried out based on 3D seismic survey conducted at one of the coalmines in the Donets Basin (Ukraine).
