Summary
A rigless snubbing operation experienced a natural gas release during ram-to-ram staging of production tubing. A broken stripping-ram yoke prevented adequate closing pressure and sealing. The operator closed the upper rams; damaged rams were subsequently removed for analysis. The BOP remained within its required certification period.
