This paper evaluates the accuracy of long-inject-long (LIL) tests for oil deposits, analyzes the fluid-displacement behavior around the wellbore, discusses the transient behavior of pulsed-neutron-capture (PNC) logs before steady state is reached, and establishes the conditions under which LIL tests work best. This paper shows that both completion and reservoir properties affect the accuracy of LIL tests.
