Injection testing conducted between March 25 and June 15, 1982 at the Raft River Site generated a substantial quantity of nonisothermal and various temperature transient pressure data. Injection pressure buiId-up measured at the wellhead strongly responds to temperature changes of the injected fluid. An increase in the fluid temperature results in an injection pressure increase while a temperature decrease is followed by an injection pressure decline. Data analyses indicate that changes in fluid viscosity and density due to temperature changes do not explain pressure build-up responses. The pressure build-up behaviors are attributed to the reservoir transmissivity changes. The absolute wellhead pressure values are significantly lower than predicted for the cold fluid injection.
