Numerical solving the problem of detecting of ultraweak diffractors in a complex acoustical medium
Some results of numerical simulating of the problem of detecting of ultraweak diffractors in a complex acoustical medium are represented. The term “ultraweak” here means that the diffractors are not determined by standard depth migration. To solve the problem of detecting we use two procedures: Reverse Time Datuming (RTD) and ...

Quantative characteristics of the CSP method
... characteristics of the CSP method, which poses to estimate its effectiveness for fracture hydrocarbon reservoirs imaging using scattered seismic waves, are defined and investigated. The most important is the sensitivity coefficient, which shows how small diffractors, compared with the shadowed reflectors, may be to be detecting by the CSP method. These dependencies from acquisition geometry and other parameters are numerically studied.
