Sedimentologically-based geomodeling approach: reducing geological uncertainties for oilfields in Western Siberia

For Late Jurassic clastic reservoir of Krapivinskoye oilfield integration of sedimentology in geomodeling workflow is presented. For main Ю13 reservoir three facies groups of shallow-marine to transition zone sediments were interpreted recognizing predictable flow units succession in the reservoir volume. Petrophysical research suggested four rock types and determined the relationship between sedimentary and recognized petrophysical units. Mostly diagenetical character of excellent quality sandstones sporadically distributed along the reservoir top was established. Finally four rock types were used for geomodeling. Porosity and permeability distribution was modeled separately for each rock types with unique poroperm relationships while saturation model was created on the base of log and averaged by Leveret’s J-function lab data.

Complex research on AV1 object of Sovetskoe oilfield development system perfection

AV1 is the largest and complex layer of Sovetskoe oilfield that is being developed for 45 years. It is characterized by high meso- and macroheterogeneity as well as by low filtration properties of the top part of the reservoir. This fact caused oil production delay and necessity of field development system improvement. Complex research on a typical 3D simulation model sector is separately realized for drilled and undrilled parts of the reservoir and directed to efficient field development system selection. New technologies and different field development systems (three-, seven-spot) are proposed depending on residual oil reserves.
