Blast Joints are thick-walled tubing joints placed adjacent to the good perforations. They provide an erosion allowance from the high velocity jetting action at the perforations that also may carry abrasive debris from the good formation. The blast joints are available 10 or 20 feet long.
The Blast Joint is used to prevent the production string from being damaged by flowing oil and gas erosion. It is often used in the double/multi-string or single string completion when the pipe column is facing the part of the perforation section. It is commonly installed as part of the tubing string and is placed in opposite sections of the wellbore where production inflow will take place.
Features:
• Heat-treated, heavy wall steel alloy, provides abrasion resistance across flowing perforated zones.
• Available in a large range of sizes and lengths.
• Threaded ends use premium threads with O-ring seals.
