The test for determining the formation fracture pressure after drilling out a seat is called a _______________.
AI Explanation
The correct answer is C) leak off test.
The leak off test is the test used to determine the formation fracture pressure after drilling out a cement seat. This test is performed to ensure the integrity of the cement job and to establish the maximum pressure that can be safely applied to the casing during drilling operations without causing formation breakdown.
The other options are incorrect because:
A) A well test is used to evaluate the production potential of a well, not to determine formation fracture pressure.
B) A casing test is used to test the integrity of the casing itself, not the formation fracture pressure.
D) A drill stem test is used to evaluate the production potential of a formation, not the formation fracture pressure.
