ISPI - Integrated Seismic Processing Interpretation; is a process designed to lead the next generation of development in exploration geology and geophysics. The process utilizes advanced, integrated, data driven regional interpretation technologies early in the exploration cycle to develop sound regional play concepts and to avoid inconsistencies that occur when technologies are applied standalone in sequential workflows.
ISPI allows geologists, geophysicists and petrophysicists to work together to create consistent geological and geophysical models encompassing the entire petroleum system from source, reservoir, trap and seal.
ISPI employs a data analytic approach to integrate well, seismic amplitude, high order RMO residuals and geologic interpretation. A calibrated sediment rock physics model and a seismic dataset that ties to the well control, are the basis for seismic inversion. Inverting the seismic data for lithology provides a level of detail that cannot be obtained with the rock physics models alone.
A physically based petrophysical model for the basin, constrained by well data, is the anchor of the ISPI methodology, as it relates velocity of p-wave and s-wave to the porosity of the sediments. The primary state variable in a basin simulator is porosity, which is related to the mean stress through the compaction law. Integrating the petrophysical rock physics model with the basin model constrains the sediment type from porosity and velocity.
Three examples illustrate the geology-geophysics connections made possible width ISPI:
