METHOD AND DEVICE FOR DETERMINIG TEST PRESSURE IN A WELL
A method for determining a test load in a well (1) in the ground (2) in which at least a cemented casing (14, 16) is placed, the method including: - arranging a pressure gauge (34) within or outside the casing (14, 16), the pressure gauge (34) being arranged to measure the pressure on the outside of the casing (14, 16) or the differential pressure between the inside and the outside of the casing (14, 16); - reading the measured values and determining the pressure on the outside of the casing (14, 16), and - determining the test pressure on the basis of the pressure capacity of the casing (14, 16) or other well components, the internal pressure and the measured external pressure.
