Cryogenic freeze services

Maintain pressure control, reduce time and cost

The cryogenic freeze service provides a temporary ice plug to maintain pressure control while facilitating the repair or removal of defective surface components. Our specialized cryogenic freeze process uses copper tubing and nitrogen for the controlled freezing of lubricators, tubing, casing, and gate valves.

Freeze operations

N₂ liquid nitrogen

The process uses copper tubing and nitrogen in a controlled manner, thus regulating and monitoring the flow of nitrogen and allowing the user to safely form an ice plug

Dry ice

Ideal for complex applications where pressure isolation is critical and other methods are unavailable. It can also help regain two barriers if a secondary barrier is lost

Applications

Quick and efficient way to establish a tested, engineered barrier
Allows placement of a barrier for production tree removal with inoperable valves
Tested ice plugs can be set across multiple strings of tubulars
Provides a tested barrier during drilling or workover well control events to facilitate removal or addition of well control components

Features

Small footprint with onshore and offshore applications
Rapid deployment with quick and efficient barrier placement
Ability to freeze, multiple casing and tubing strings, wellhead components, drillpipe and workover strings
