Evaluation and monitoring of enhanced recovery projects in California and cased-hole exploration and recompletions in West Texas based on the continuous carbon/oxygen log
Potential California reservoirs for secondary and enhanced oil recovery (EOR) projects are typically of moderate to high porosity with formation waters ranging from fresh to brackish. Under these conditions, pulsed neutron devices, such as the continuous carbon/oxygen (C/O) log, are invaluable for monitoring sweep and displacement efficiency, locating fluid or gas breakthrough, and evaluating residual oil saturation (ROS). In west Texas the C/O log assists in the re-evaluation of partially depleted oil reserves and exploration for bypassed oil in old wells in mature producing areas. Field case examples, including results of subsequent production tests in the Yates, Seven Rivers, Queen, Grayburg, San Andres, Glorieta, and Clearfork formations are presented.
