Schlumberger at OTC 2013

At this year’s OTC event Schlumberger is cementing. The system creates a strong, featuring technologies, services, and impermeable grid that stops mud from flowing into methodologies ranging from exploration to well high-permeability and naturally fractured zones. It is designed to withstand additional pressure from completions for reducing drilling risk in deepwater environments. Several case histories will be mud density increases and any future drilling or cementing operations. The treatment saves presented at the booth demonstrating how the barrels of fluid during placement right combination of people, processes, and thousands of and reduces nonproductive time caused by lost technologies can improve success rates in circulation.

Saturn’s drain and formation evaluation data with the reservoir assembly positions four self-sealing suction model—and uses appropriate interpretation probes at 90° intervals against the borehole wall techniques to quickly analyze the data—helps to pull fluid circumferentially from the reservoir. avoid kicks from over-pressured zones.
