===Pressure buildup tests===
In a pressure buildup test, one should stabilize the rate in the tested well for several days, that is, maintain the rate approximately constant. Then place a pressure measuring device as near the perforations as possible several hours before shut-in. Shut the well in and let the pressure build up. The rate at which pressure builds up with time reflects the formation properties. (For more details of pressure buildup and flow tests, see Matthews and Russell.<ref name=pt09r16>Matthews, C. S., Russell, D. G., 1967, Pressure buildup and flow tests in wells: Dallas, TX, Society of Petroleum Engineers Monograph Series No. 1, 172 p.</ref>)
