... 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...

... 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...

... expected to suspend the wellbore for several months and then remotely open the wellbore without intervention. However, the RIV remote opening mechanism was compromised due to well conditions and compatibility issue in two wells, prompting contingency operations including coiled tubing and electric-line...

... Abstract Multi-stage hydraulic fracturing of coal bed methane wells using coiled tubing in Raniganj Coal Bed fields in the eastern part of India has been steadily increasing over the last several years. The completion process of these wells involves various kinds of explosive perforating...

... for protection against barium sulfate scaling from the mixing of formation water and injected seawater. These treatments were to be delivered to subsea production wells in water depths of ~4,200 ft. The design basis of this hydraulic intervention system involved dual, open-water coiled tubing strings deployed...
