The drilling effort in the LFN field faced many challenges, such as those experienced in LFN-1 well during drilling 8-1/2" hole section in Lower Nief formation whose lithology is limestone, partial loss occurred and in the consecutive formation of Kola with Shale whose...

... directional hole section with dogleg severity (DLS) upto from 1.5°/100 feet. This study presents a novel directional drilling strategy utilized in a deep offshore oil well with high inclination for achieving the challenge imposed by setting the casing shoe in limestone formation, deepest in the region (~8000...

... Abstract In the present paper, numerous stuck pipe events were carefully studied in wells drilled in the Kingdom of Saudi Arabia between 2013 and 2014. Stuck pipe events were analyzed per different hole sections (from 34 in. to 5 7/8 in.) and it was noted that overall the number of stuck pipe...

... Abstract An operator is delivering complex extended-reach drilling (ERD) wells from an offshore platform and experiencing up to three weeks of nonproductive time (NPT) to pull out of hole (POOH) bottomhole assembly (BHA). Multiple BHA’s have been lost in the 17 ½-in. hole section in faults...
