Abstract:
1. A computer-implemented method for petrophysical rock typing in an oil or gas reservoir or field, comprising: a) selecting a Data Scenario (DS) for the oil or gas reservoir or field based on at least one or more of a well density, well log data, core data, production data, or combinations thereof from the oil or gas reservoir; b) determining a plurality of Depositional Rock Types (DRTs) for the oil or gas reservoir or field, each DRT being based upon one or more depositional attributes associated with the oil or gas reservoir or field; c) determining a Diagenetic Modification (DM) from a plurality of diagenetic modifiers or primary textures associated with the plurality of DRTs; d) selecting a predefined Reservoir Type (RT) based on the Diagenetic Modification (DM) and corresponding to the plurality of DRTs and associated with the oil or gas reservoir or field; e) determining at least one pore type based on at least one or more of the core data, mercury capillary injection pressure (MICP) data, well log data, or combinations thereof from the oil and gas reservoir; and f) transforming the plurality of DRTs, the Diagenetic Modification (DM), and the at least one pore type into a plurality of Petrophysical Rock Types (PRTs) associated with the RT, wherein at least one of (a) through (f) is performed on a computer, wherein the computer comprises a computer processor and a storage medium and a program recorded thereon for directing the computer processor to facilitate the implementation of (a) through (f).
