... Below are some of the factors that historically have affected perforating efficiency in Thailand: In this system, each gun has a compact expendable docking module - a modularized initiator equipped with a radio frequency safe detonator and an addressable switch. This system can be used...

...+ feet) deeper than original estimates. One of the wells was perforated below the interpreted original OWC and has produced at high rates without significant water production. The concept of monobore completion and use of modular gun assembly were tested. Lesson Learned: Information was valuable...

... Abstract Two new innovations - all automatically released gun hanger, and a modular gun-deployment system have recently been introduced to the oilfield to better support perforating needs in wells in which the completion configurations differ from the older, traditionally accepted designs...

... techniques considering safety, operating efficiency, conveyance method and well performance. The optimal solution was to leverage an advanced live-well deployment system to recover the perforating guns under live well conditions. The system was a modular live-well system (conveyed using coiled tubing...

... completion of the perforation as there was insufficient rathole to leave the guns in the hole. An oriented modular perforating system was developed so that the above conditions could be achieved. The requirements were met by installing a gun anchor in the well before the completion was installed...

.... Acknowledgments One of the challenges was to adopt a system that would allow at least the deep sands to be perforated underbalanced. The first type of perforating used in these completions is extreme underbalance perforating (EUB), which employs a modular gun system. This technique takes underbalance...
