... Abstract The plug-and-perf (PnP) method is widely used globally for multistage fracturing operations. With only a few jobs performed worldwide, coiled tubing (CT) assisted PnP operations in high-pressure/high-temperature (HP/HT) wells are largely uncharted and most challenging. The "A" field...

... Abstract The Bureau of Safety and Environmental Enforcement (BSEE) first published High Pressure/High Temperature (HPHT) regulations at 30 CFR 250.807 in 2010. Additional HPHT regulations were published in 2016. In 2019, BSEE published three (3) Notices to Lessees and Operators (NTLs...

... Coiled tubing (CT) sand plug operations associated with multistage fracturing operations in high-pressure/high-temperature (HP/HT) wells are very challenging, in part because of the small number of such jobs that have been performed worldwide. The wells in "A" field in India have HP/HT...
