Using SBED[TM] from Geomodeling, Statoil geologists, petrophysicists and reservoir engineers have been able to capture the fluid flow impact from complex, fine-scale inter-layering within heterogeneous reservoir
units, improving their reservoir property simulations and reserve predictions.
For quite some time, we have been searching for a reliable downhole monitoring system for our unique and heterogeneous reservoir
type (fractured granite basement), which has extremely high downhole temperatures up to 312 degrees Fahrenheit.
Based on the control technique of the microsphere diameter and the matching relationship between the diameter and pore constriction, the plugging ability of microspheres in heterogeneous reservoirs
Moreover, infill wells are considered to be frequently used option in Pakistan because in this scenario these wells can be utilized further as injector wells for secondary and tertiary recovery, however in case of water floods these wells should be oriented properly to avoid excess production, this practice accelerates recovery in heterogeneous reservoirs
by improving continuity between injectors and producers highlighting this aspect is also a main objective of this paper.
2) By applying this model from one single layer to multilayers, this method gives a quantitative expression of sweep efficiency of the three stages during waterflooding, which can be used to accurately calculate the sweep efficiency of heterogeneous reservoirs and evaluate the degree of waterflooding in multilayer reservoirs.

A proper description of capillary pressure and relative permeability curves including hysteresis has significant impact on the field performance predictions and determination of remaining oil saturation, especially for heterogeneous reservoirs
, which will significantly impact any future IOR/EOR options," he said.
In layered and heterogeneous reservoirs
water movement front is not always uniform due to different permeability in layers, leading to breakthrough of water in high permeable layers while in some layers oil not being displaced efficiently.
