Conceptual facies model of clinoform type sedimentary basin

Authors: L.N. Ivanova, L.V. Lapina, М.V. Lebedev, R.B. Yanevits (TNNC LLC, RF, Tyumen)

Key words: facies model, facies sequence, facies unconformity, clinoforms, lithologically sealed structural traps.

A conceptual facies model of sedimentary basin describing it as stacked facies sequences confined by facies unconformity was generated. A conceptual model of clinoform sedimentary basin was proposed that allowed prediction of, firstly, structural traps with lithologic seal associated with micro-clinorform structure of shelfal sand reservoirs, and, secondly, structural traps with lithologic seal associated with dissecting the Achimov sheet sand by mudstone member markers into bodies with no hydrodynamic communication. Examples of such targets mapped in one of the biggest fields of West Siberia are shown. References
