The leak off test is performed to determine the maximum pressure or drilling fluid density at which the formation can get to the fracturing point. Repeatability is defined as the discrepancy between two consecutive measurements of a given pressure at the same temperature. The combination of the downward movement of the tubing and the upward movement of the fluid or piston effect results in an increase in pressure at any given point in the well. Data processing by data eskyle. In producing wells, downhole shut-in is performed by setting a valve assembly in the tubing before performing the test.
