The system is expected to enable Total to effectively drill and exploit reserves in its Victoria field in the North Sea.

The two companies will be utilizing new technologies to accomplish the goals of this project. These include a downhole refrigeration system, cold-plate technology, flasking and phase change material, all designed to function under the high shock and vibration encountered while drilling.

The work may lead to an expanded suite of logging-while-drilling sensors capable of operating at elevated temperatures.

Brady Murphy, vice president of Sperry Drilling Services, said: This project represents a commitment from both companies to push the limits for extracting hydrocarbons from high-temperature and deeply buried reservoirs. We already have ultra-high-pressure tools rated to 30,000 pounds per square inch.
