Study of the effect of injecting cold or hot water on the operation of an oil field

Journal Article:

Abstract

Several Soviet reservoirs contain either highly paraffinic or viscous crude oils, where recovery by an ordinary waterflood is poor. Under such circumstances, hot water injection appears to be advantageous. Hot water injection is advisable when: (1) the reservoir is heterogeneous and contains low-permeability sections; (2) the oil is saturated with paraffin at reservoir temperature; and (3) reservoir pressure is only slightly higher than static pressure. In Uzen field, hot water injection should recover 1.5 times more oil than would be recovered with cold water. Various problems involved with hot water injection such as equipment and methods of heating the water, transportation of the water of the wellhead, heat losses in transport of hot water, and well equipment for handling hot water are discussed. Calculations indicate that it should be possible to transport 100/sup 0/C water through a 5 km pipeline with a 4/sup 0/ to 6/sup 0/C temperature drop; then deliver to the well bottom at a temperature of 90/sup 0/ to 92/sup 0/C.
