Abstract EN
The Upper Morrow sandstones in the western Anadarko Basin have been prolific oil producers for more than five decades.
Detection of Morrow sandstones is a major problem in the exploration of new fields and the characterization of existing fields because they are often very thin and laterally discontinuous.
Until recently compressional wave data have been the primary resource for mapping the lateral extent of Morrow sandstones.
The success with compressional wave datasets is limited because the acoustic impedance contrast between the reservoir sandstones and the encasing shales is small.
Here, we have performed full waveform modeling study to understand the Morrow sandstone signatures on compressional wave (P-wave), converted-wave (PS-wave) and pure shear wave (S-wave) gathers.
The contrast in rigidity between the Morrow sandstone and surrounding shale causes a strong seismic expression on the S-wave data.
Morrow sandstone shows a distinct high amplitude event in pure S-wave modeled gathers as compared to the weaker P- and PS-wave events.
Modeling also helps in understanding the adverse effect of interbed multiples (due to shallow high velocity anhydrite layers) and side lobe interference effects at the Morrow level.
Modeling tied with the field data demonstrates that S-waves are more robust than P-waves in detecting the Morrow sandstone reservoirs.
