Summary:
C31 EFFECTS TO BE CONSIDERED WHEN PLANNING LATE STAGE DEPRESSURISATION 1 DAG STANDNES ARNE SKAUGE AND ØYSTEIN PETTERSEN Centre for Integrated Petroleum Research University of Bergen Bergen Norway Abstract The main effects of depressurisation influencing oil recovery is changes in; fluid properties fluid saturation phase mobilities and rock properties. This paper includes a mechanistic simulation study including effects involved in depressurisation. The emphasis of this paper is special effects related to rock compaction which may occur during depressurization (DP) in mature oil fields. Empirical data indicate that reservoirs containing high-permeability channels (kc) in a background (kb) of more low-permeability soil
