Industry First – Sheared and Sealed a 6.75” Drill Collar

HOUSTON – April 19, 2011 – Radoil, Inc. is pleased to announce that it has successfully completed an oil industry first by designing and producing a shearable drill collar.

Today at GE Oil & Gas, Drilling & Production’s (GE) Houston, TX BOP test facility a group of 11 deepwater industry individuals witnessed the 1725 psi. shearing and subsequent BOP sealing (seal pressure test 10K) of Radoil’s new drill collar design. This is a significant step forward in DRILLING SAFETY as it provides a replacement for the traditional un-shearable solid steel drill collars.

Radoil would like to thank GE for their assistance and involvement in providing a standard 18 ¾”, 15K, Hydril Pressure Control Compact Ram blind shear system with 3000 psi bonnet and 22” operator to shear the drill collar. The new drill collar is a patent pending design which includes an outer 6.75”, .5” wall shell and an inner 2.157”, .109” wall bore pipe with the interstitial space filled with lead. The shearable drill collar has a weight of 141.9 lb/ft versus 108.3 lb/ft with solid steel drill collars. The drill collar’s lead filled design makes it shearable while providing the desired weight and stiffness for normal drilling operations.

Radoil is an ISO 9001:2008 certified company which designs, manufactures and sells a variety of products that are used primarily in deepwater drilling processes and BOP control systems. These products range from umbilical reels to hot stabs to fairings to shearable drill collars to bullseye slope indicators. Radoil holds numerous patents most of which apply directly to its variety of oil and gas drilling related equipment
