This was the third time the RMR system has been used on the Malikai Project since the initial field development in 2014.
RMR (Riserless Mud Recovery) is a dual gradient top-hole drilling technology that allows drilling of the riserless section with full volume control and returns of the drilling fluid back to the rig. For the Malikai Phase 2 Project it was used to reduce the amount of casing strings and to enable volume control and good hole cleaning in the 17 ½” section. The system has been successfully used on more 500 wells since it was first deployed operationally in 2003. Enhanced Drilling’s RMR system was successfully used on the Shell’s Malikai TLP to drill five top holes in batch in just under 500 m of water.
By deploying the RMR system, it allowed the company to closely monitor the wells to detect any losses and gains as well as determine when, and if, the cement was returned to mud line. That resulted in reducing the amount of excess cement and improved ability to document a good cement job.
Due to the Covid-19 pandemic in 2020 and the various travel restrictions this caused, the project faced many challenges. Nevertheless, the were many positives that came out of it and one of those was Enhanced Drilling’s testing of the remote-control technology kit. The system was run remotely from Norway for one whole shift. From the remote-control room in Norway, the Enhanced Drilling Operators were able to communicate with the driller in real-time and operate all aspects of the RMR system. In the future this could mean reduced offshore crew and eventually full remote capabilities.
