Rationale for selection of consolidated blocks of multilayer and multi-deposit formations for development analysis

Authors: A.V. Fomkin, A.Ya. Fursov (VNIIneft OAO, RF, Moscow)

Key words: geological blocks, reserve density, inadequate development, priority of reserve development, modeling tasks.

In the Upper Oligocene sediments there is a contradiction between a large number of alternations and deposits and fast production decline during development. There is a need for formation consolidation to create conditions for real development adjustment. This paper presents an approach to form consolidated blocks with different reserve density and different reserve recovery status based on considerations of facies and tectonic features of the field. Reserve quality in different blocks is comparatively assessed and three-dimensional modeling tasks for development system evaluation are set out.
