Rabaa-1 is a key exploration well drilled in Block 71 in Yemen. 5 spuds was schemed in the well and after 216 mm hole drilled, 127 mm DP with liner running tool got stuck during 177.8 mm liner cementing operation. After this incident happened, drilling experts of SIPC E&P Yemen immediately made feasible technical procedure and took effective measures to deal with the difficulties by means of the actual down-hole conditions. According to these technical measures, it took 14 days to conduct the wash-over and back-off fishing operations and altogether 193.4 m of down-hole fishes with liner running tool finally had been pulled up. Liner cement incident has been successfully diminished not only saving the life of the high output oil-well, but also giving a good lesson on liner cementing operator in Yemen.
