Alloy Barriers

ALLOY BARRIERS - A downhole alloy seal is created by melting a low-melt-point alloy using a specialised heater. Once melted, the alloy flows into place and solidifies, forming a durable, pressure-resistant barrier for applications such as restoration of well integrity, production enhancement or plug-and-abandonment (P&A) operations. Annulus alloy barriers are considered as an alternative to cement, where a smaller volume of alloy can offer a superior long terms seal. 

DEPLOYMENT TECHNIQUES - The choice of the most appropriate alloy deployment technique depends on wellbore geometry/restrictions, wellbore deviation, setting depth.  These factors determine the size and placement of the heater needed to effectively melt the alloy and create a robust seal. By selecting the appropriate technique, operators can ensure effective heat management and optimised seal performance, even in complex or high-loss thermal environments. 

The primary alloy barrier deployment techniques are shown below.
