− | RFTs, DSTs, and bottom-hole pressure buildup tests measure formation fluid pressures. Pressure gauge accuracy is a critical factor in all three tests, but the BHP measurement is generally more precise due to the greater time taken for the test. Generally two types of gauges measure pressures: strain and quartz. The table below shows the accuracy and precision of both types. | + | RFTs, DSTs, and bottom-hole pressure buildup tests measure formation fluid pressures.
