Abstract
ABSTRACT An innovative new water injection controller has been developed which will significantly improve water injection into wells, especially those exhibiting no measurable surface pressure. The new system consists of a motor control valve, turbine meter, injection controller, and bottom hole pressure (BHP) device, with power supplied by a solar panel, negating the need and added expense of running power to each well. The new system has the capability to monitor well BHP, compare the BHP against a preset value, and adjust the injection rate accordingly. The system will eventually have the capability to run step-rate tests and pressure fall-off tests automatically, as well as perform temperature surveys. Since the unit is installed in the tubing in much the same manner as a wire line tool, no pulling unit expense is incurred.
