Step Rate

Step-rate test are run on injection wells to determine the maximum injection rate possible without fracturing the reservoir.

The test is conducted by recording the injection pressure and injection rate at several increasing injection rates. When an increase in rate does not result in a proportionate increase in injection pressure, fracture pressure has been reached. The installation of a SPIDR for a step-rate test is shown on the left.

Step-Rate Testing Tech Alert

May. 4th, 2005 11:29 am

Injecting at pressures significantly below the parting pressure results in reduced oil recovery rates whereas injecting at pressures above the parting pressure may result in loss or misdirection of the injection fluid and reduced oil recovery. STEP-RATE testing (SRT) is the primary method used to determine the maximum safe injection pressure without fracturing the reservoir rock.The test procedure requires the test well to be either shut in or stabilized at a reduced but constant injection rate ... read more
