FORMATION CONDITION RECONSTRUCTION OF THE SIRACHOY PRODUCTIVE FORMATION (D3src) FOR THE ONE OF THE FIELDS OF TIMANO-PECHORA OIL AND GAZ PROVINCE ON THE BASISOF A COMPREHENSIVE STUDY OF SEISMIC AND FIELD GEOPHYSICAL DATA
Definition of the carbonate formation structure is rather complicated challenge. Well data is not enough for the solving of this task. This article presents the example of the facial zoning of a Upper Devonian Timan Pechora OGP carbonate reservoir of the Sirachai reservoir using cluster and seismic facies analysis was considered. Complex with the well-logging and core data, paleotectonic reconstructions allowed to reconstruct the history of Sirachai reservoir to justify the traps morphology and to identify the high filtration and capasity reservoirs.
