Free Point/Backoff Operations 

Renegade has the equipment and knowledge to quickly free stuck pipe or tools

When pipe or tools become stuck in the well, it can quickly become one of the costliest challenges an operator is faced with. Until the problem is resolved, other issues including delayed drilling, increased NPT and additional expenses for equipment and crew become critical. When this problem occurs, you need a company that provides fast response, safe operations and a knowledgeable crew with the best equipment.   

Quickly determining the stuck point, loosening or severing the stuck string and then recovering as much of the stuck tool or string as possible is imperative to get wellsite operations going again. Renegade has the equipment, personnel and experience to provide the solution when your toolstring or pipe becomes stuck. 

For successful pipe recovery and stuck tool operations you must first determine the free point of the tool or pipe. The free point is the depth at which the tubing, casing or tool that is stuck in the borehole is free to move. This will be the point at which recovery operations can begin.  

Renegade’s free point tool provides vital information that aids in cutter type selection and helps identify the location to separate pipe. Always ran with a CCL, the free point tool is first positioned at a known free spot to set up the tool and check proper tool functionality.

A sensor picks up movement in the assembly associated with tension, compression or torque. This signal is sent to a surface free point panel for display and recording. Renegade specialists continue the process until zero movement is detected by the sensors. 

Next the connection or pipe must be severed to pull the remaining string out of the hole. This can be accomplished by applying a ‘back off’ or reverse torque and at the same time detonating an explosive charge inside the nearest string connection.

Circulating Pyro Torch 

Effective operations when annular flow is required for the Radial Cutting Torch

MCR Oil Tool’s circulating pyro torch was developed using the same principles as the successful and field-proven radial cutting torch (RCT) system. However, in some conditions, adequate flow into the annulus is required when executing a successful RCT job. Explosive perforators and punchers are not reliable at producing consistent holes that provide sufficient flow, having a dramatic effect on success when cutting with the RCT. The circulating pyro torch delivers the required annular flow prior to cutting and provides a consistent and reliable punch in coil tubing, casing, and drill pipe. By utilizing the latest in MCR’s proprietary non-explosive, non-hazmat rated fuel technology, you can complete your job faster and safer than ever before. 

  • Non-explosive
  • Non-hazmat rated fuel
  • Radio safe
  • Operates in temperatures up to 500°F (260°C) and pressures up to 25,000 psi (172.4 MPa)
  • Perforates all steel, high chrome, and plastic-coated tubulars
  • Perforates in exotic fluids or dry pipe
  • Single/dual perforations in sizes from 0.38 in 2 to 7.0 in 2
  • Deployable within hours and not days
  • Minimizes downtime and associated costs

Operation 

All Renegade operators are trained and certified by MCR for proper tool operation for safe and efficient operations. 

MCR’s circulating pyro torch assembly is lowered into the well to the desired depth. MCR’s thermal generator ignites and activates the primary fuel load causing an increase in internal pressure. Following internal pressure rise, plasma exits the torch which perforates the target pipe. By design, the CPT cutting jet forces the tool against the wall of the pipe; the high frictional forces between the CPT and the wall of the pipe are greater than the thrust forces exerted by the pressure bubble, stabilizing the perforator to make the cut. It is this feature that allows MCR’s perforators to function properly in plugged pipe situations.

Radial Cutting Torch 

Safe, effective operations to sever tubing, casing, drill pipe or coiled tubing

MCR Oil Tool’s radial cutting torch (RCT) is a patented cutting device used to sever tubing, casing, drill pipe, and coiled tubing without the use of explosives or hazardous materials, making it one of the safest pipe cutting tools on the market. Using advanced technology, the patented nozzle and proprietary mixture of various powdered metals produces jets of highly energized plasma to cut virtually any type of pipe in any well environment. Because the RCT does not use explosives or hazardous chemicals, the tool can be shipped almost anywhere in the world within 24 hours, saving significant time and associated costs, while remaining compliant with safety regulations. 

Operation 

All Renegade operators are trained and certified by MCR for proper tool operation for safe and efficient operations. 

The RCT assembly is lowered into the well until the desired depth is reached. MCR’s thermal generator ignites and activates the primary fuel load; highly energized plasma is produced causing an increase in internal pressure. Once the pressure exceeds that of the wellbore, the protective sleeve is displaced exposing the nozzle to the wellbore. Plasma exits through the nozzle to sever the targeted tubing, casing, drill pipe or coiled tubing in wellbore temperatures up to 500°F (260°C) and pressures to 20,000 psi (137.9 MPa). 

  • Undersized for restrictions 
  • Suitable for HPHT environments
  • Cuts up to 9-5/8-in. casing 
  • Custom tools available 
  • Non-HazMat rated RCT’s currently available: RCT-SP

Stuck Pipe Log

Stuck Pipe Log

Home » Tool/Pipe Recovery
»The stuck pipe log is deployed from our standard logging unit and can be run through drill pipe, casing or tubing.

Stuck Pipe Log 

When wellsite problems occur, Renegade has the full range of options to successfully free stuck pipe.

The stuck pipe log uses acoustic measurement techniques to provide a continuous record and evaluation of a stuck pipe string. This logging service can be performed through drill pipe, casing, or tubing to identify problem areas. 

Acoustic pulses, initiated at the instrument’s transmitter, travel through the pipe string and are measured at the receiver. The acoustic energy level at the receiver is proportional to the degree of stuck pipe. Similar to conventional cement bond logging measurements, low attenuation readings indicate free pipe and high attenuation readings indicate stuck pipe. 

The stuck pipe log is superior to free point evaluation because the stuck pipe log is used to determine multiple stuck points throughout the well instead of just the first problem area. With a complete picture of the situation, an informed decision and subsequent pipe recovery plan can be devised, saving time and money.
