SPEX Offshore offers MCR Oil Tools’

Radial Cutting Torch (RCT) tool for

severing all common sizes of tubing,

casing and drill pipe. The RCT tool is a

patented cutting device that does not

utilise explosive components or

dangerous chemicals that may pose

handling issues. The RCT can be

deployed within hours and

significantly reduce non-production

time.

RCT technology is one of the most efficient tubular

cutting systems currently available. Ranging in sizes

from 3/4” to 7” OD, the RCT cuts both normal and

exotic steels and operates in pressures up to

25,000psi (173 MPa) and temperatures as high as

500 °F (260 °C) in any orientation: compression,

tension, neutral or in torque.

The typical RCT toolstring consists of the Torch

(which includes the cutting nozzle, torch

extensions, Pressure Balance Anchor, and Thermal

Generator™). Additionally, centralisers are

positioned at the top and bottom of the toolstring

to ensure the tool is fully concentric within the

tubing, ensuring a precise cut every time.

Principles of Operation

When the RCT is run in hole to the desired depth, a

firing voltage is applied to the Thermal Generator™

causing the main fuel load to be activated. The

resulting exothermic reaction produces molten

plasma. Within 25 milliseconds, a stream of

ceramic integrated plasma exits the tool through

the nozzle, severing the target tubular. By design,

the advanced technology of the RCT tool erodes

the target material instead of displacing it; cuts are

non-flared and fracture-free with minimal to zero

backside damage, leaving a clean profile for

subsequent operations. Once the cut is made, the

RCT tool assembly is easily removed from the

wellbore.

MCR Oil Tools’ Radial Cutting Torch

Provides the industry with the safest and most

efficient pipe cutting alternative to explosives or

hazardous chemicals

7-5/8” 33.7# L80

5” 23.2# 13% Chrome

The RCT can be run on electric line, slickline (with

MCR’s Remote Firing Mechanism (RFM) or other

downhole power unit / triggers) and on coil or pipe

with a pressure firing system.
