ABSTRACT:
In a method for performing a step rate test on an injection well, a portable pumping unit is employed to increase the pressure on the injected water to a predetermined level in order to carry out the step rate test, and the predetermined pressure and flow rate are maintained and controlled by separating a portion of the pressurized water outflow from the portable pump from the main stream thereof, and the separated portion of pressurized water is returned to the water storage tank which feeds the input to the portable pump.
