Comprehensive criteria for substantiation of development objects allocation
One of the criteria is the similarity of the geophysical parameters. In this approach, the assessment of "similarity" is considered for each parameter separately. A significant difference among the layers’ individual characteristics, such as efficient oil-saturated thickness, absolute permeability and viscosity reservoir oil can create in the layers very close filtering conditions and ensure equal wells flow rates as measured by the hydro-conductivity of these productive layers if other conditions are constant (ΔP, R к, r c, S). The suggested approach to the selection of the object subject to development is illustrated by consideration of some oil field that contains seven terrigenous and carbonate reservoirs. The degree of conductivity parameter kh "similarity" as well as the layers’ hydro-conductivity, i.e. the set of filtration conditions, witness the fact that carbonate collector of Tula reservoir and terrigenous collector of bobrikovsky reservoir appear similar to a much greater extent than the degree of carbonate collectors of Tula and Kizel reservoirs.
