Recovery factor versus Reservoir Complexity Index (RCI) – a tool for estimating potential ? 0.70 y = -0.776x + 0.7779 R 2 = 0.8095 0.60 0.50 Utv grad 0.40 0.30 0.20 0.10 0.00 0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 0.90 08.02.07 RCI 12
Reservoir Complexity Index (RCI) – parameters used in evaluation Complexity attribute Description Low complexity 1 2 Complexity score 3 4 High complexity 5 Average permeability Describes the pore volume weighted average permeability in the main flow direction of the defined reservoir. mD > 10.000 1000- 10 00 0 100-1000 10-100 < 10 Permeability contrast Describes the permeability contrast between geological layers/facies types, and is calculated as log10[Kmax/Kmin] 4 Structural complexity Describes how fluid flow between wells is affected by fault density, fault throw, fault transmissibility, …. The fault properties does not restrict fluid flow. The fault properties restrict fluid flow significantly. (High density of faults with throw larger than reservoir thickness and/or 'zero' transmissibility). Lateral stratigraphic continuity Describes the stratigraphic continuity of the flow units in the main flow direction within the defined reservoir High degree of continuity Highly discontinuous. Difficult to predict/describe injector/producer connecting flow units. STOOIP density Describes the areal concentration of STOOIP and is defined as STOOIP/area (mill. Sm3/km2) >4.5 2 - 4.5 1 - 2 0.5 - 1 < 0.5 Coning tendency Describes the coning problems associated with a gas cap or aquifer support. Large complexity only in cases where the oil band is thin. No coning tendency. Some coning problems from gas cap or aquifer Thin oil zone and production severely restricted by gas or water coning problems 08.02.07 13
