ONE of the world’s leading multi-energy companies, Repsol, has signed up to use Enhanced Drilling’s RMR® Riserless Mud Recovery system in the North Sea in a multi-well deal due to commence in May 2022.
RMR® helps Repsol unlock valuable reserves
Repsol has turned a decommissioning project into a producing asset, where some of the existing infrastructure and design will be reused together with new facilities.
To help unlock the recoverable reserves at the Yme field, Enhanced Drilling’s zero-emissions RMR® Riserless Mud Recovery system will be used together with the Cuttings Transport System to drill three topholes section and three 17 ½” sections with mud returned to the rig without the use of a riser. The planned batch campaign will set all three top-holes concurrently.
By using the RMR® system, not only can the engineered, weighted drilling fluid be used to mitigate any top-hole instability challenges, the system also enables the well to be monitored - a unique benefit in top-hole sections. Also, as all drilling fluid is returned to the rig, no fluid or chemicals are released during drilling - this provides protection to sea, saves operating cost and reduces the required mud volume compared to PAD (pump-And-Dump) operations.
‘Over 1000 wells reached’
Enhanced Drilling is thrilled to be working with Repsol on the redevelopment of the Yme field. Enhanced Drilling's VP Sales & Marketing, Bernt Eikemo, said:
“We are very pleased that Repsol has chosen our zero-emissons RMR® and Cuttings Transport System (CTS) solutions for this project. Overcoming top-hole instability can be a challenge, but, with over 1000 wells reached to date, our proven offshore technology not only helps create top-hole stability and associated cost savings, but also reduces emissions and discharge to sea during drilling”
Technologies and services
Enhanced Drilling aims to help oil companies around the world solve challenges on all types of subsea wells, from top-hole drilling, intermediate section drilling, and reservoir drilling through the whole well construction process including completion. Enhanced Drilling provides technologies and services that have been deployed on more than 1000+ wells worldwide including RMR®, EC-Drill® Managed Pressure Drilling system, Cuttings Transport System (CTS) (which is used to take cuttings away from the wellhead area), MPC Managed Pressure Cementing (MPC®), a complementary technology to RMR®, and the newly developed EC- Monitor system (EC-M).
