RAZORBLADE

The RAZORBLADE is a non-explosive, reliable and cost-efficient punching tool which can punch single or multiple holes in a single run and operates as a Plug & Play add on to the RAZORBOSS Plug & Play platform of tools. The RAZORBLADE tool delivers circulation holes in a range of tubing and casing sizes from 2-7/8” to 9-5/8” and does not damage the outer or annular pipe string. RAZORBLADE also has the ability to create centralisation or standoff between tubing and casing or casing to casing enhance cement placement.


RAZORBLADE utilises the RAZOR Control Module (RCM), a disposable alkaline battery pack for power requirements and which delivers a single punching operation per pack. The alkaline pack is easy to handle, easy to transport, recyclable and is wellsite safe. RAZORBLADE can be run in real time or memory mode and is suitable for use with all conveyance methods including mechanical slickline, real time slickline, electric line, coiled tubing, sucker rod or jointed work string. The RAZORBOSS platform records voltage, current, status, time and temperature for quality-assurance purposes.
