This revolutionary new technology significantly improves the efficiency and safety of plug and abandonment, relief well and carbon capture storage projects. This no-access-while-drilling solution allows for the continuous advancement of the directional drilling assembly, coupled with an instantaneous ability to query and command the onboard magnetic ranging field generator, magnetic ranging sensor and gyroscope.
The CTRWD™ system uses active magnetic ranging to collect relative wellbore proximity ranging data without having to extract the drilling assembly for a wireline run.
This eliminates the need for costly, time-consuming and sometimes risky open hole wireline operations and can save 50% or more on a typical plug and abandonment project.
Leveraging the underlying technological advantages of DeadSet™, the BHA can deliver high voltage electrical energy into the formation to establish a magnetic signature on the target well, which is, in turn, sampled and interpreted in the BHA.
The CTRWD™ system delivers a step change for the industry to improve their bottom line, increase operational efficiencies and deliver projects safely for all stakeholders.
Plug and Abandonment
This is the process of permanently closing a well. CTRWDTM can be used to locate the wellhead and ensure that the plug is properly placed.
Relief Well
This is the process of drilling a new well to relieve the pressure of a failed well that has experienced a blowout. CTRWD can be used to identify the location at which the relief well should intersect the origin well.
Carbon Capture Storage
This is the process of separating, treating and transporting carbon to a long-term storage location. CTRWD can be used to isolate the carbon dioxide from the source to promote the reduction of harmful emissions.
Increased Efficieny
The CTRWD™ system can save 50% or more on a typical plug and abandonment project. The system eliminates the need to withdraw the drilling assembly for a costly, time consuming and sometimes risky open hole wireline operation.
Improved Safety
The CTRWD™ system eliminates the risks and complexity associated with the need for open hole wireline operations, while simultaneously allowing for the coiled tubing BHA to be deployed “under pressure” with continuously present well control barriers that are not possible during rig assisted directional drilling or wireline operations.
Increased Versatility
The CTRWD™ system is also ideally suited for high inclination (>50) and motherbore exit and re-entry applications, where standard drill rig operations struggle. This is because the CTRWD™ eliminates wireline runs and has a small overall tool size (3.5”) allowing the drilling system to mill, exit, range, steer and re-enter to plug smaller tubulars typically found in deep complex abandonment projects.
