LEAKOFF TESTING

A class with identifier http://staging4.data.posccaesar.org/iso/15926-4/rdl/RDS17659020

MetadataThis section provides information about 'RDS17659020'.

Definition<LEAKOFF TESTING> is <TESTING> to determine the strength or fracture pressure of an open formation
ISO number16133
NoteA leakoff test is usually conducted immediately after drilling below a new casing shoe. During the test, the well is shut in and fluid is pumped into the wellbore gradually to increase the pressure that the formation experiences. At some pressure, fluid will enter the formation, or leak off, either moving through permeable paths in the rock or by creating a space by fracturing the rock. The results of the leakoff test dictate the maximum pressure or mud weight that may be applied to the well during drilling operations. To maintain a small safety factor to permit safe well control operations, the maximum operating pressure is usually slightly below the leakoff test result.
