Summary
A casing pressure test reached 1500 psi after cement and the float collar were drilled out using a mud motor. Pressure failed to bleed back through the motor. Opening the BOP subsequently expelled the rotary table’s inner bushings, despite an instruction to stand back. No injuries were reported.
