Deviated, high-clay well prevents conventional reperforation
When a critical interval was not producing as expected, PEMEX decided to
reperforate the zone. However, due to some deployment limitations, this zone
was inaccessible by wireline intervention. Like many wells in this area, all
efforts were made to avoid killing the well or pumping fluid into the
formation, which could delay putting the well back into production.
Real-time CT technology enables accurate, selective perforating
Schlumberger proposed piloting the ACTive OptiFIRE CT real-time
selective activation system, the industry's first coiled tubing technology that
allows perforating guns to be selectively activated downhole. Unlike most
conventional perforating solutions, the ACTive OptiFIRE system does not require
any working fluid for firing head activation. Instead, it relies on real-time
fiber-optic technology to detonate the perforating string.
