A new seal arrangement for RCDs

We have completed separate effects testing of the key components of a new rotary seal arrangement that enables rotary control devices (RCDs) to operate without the aid of an external lubricant pressurization system. The sealing arrangement is comprised of two rotary seals with a pressurized barrier lubricant between them, a small local compensating piston, and a self-actuating lubricant return valve. This arrangement is shown schematically in Figure 1.

This sealing arrangement has four key advantages. First, the differential pressure acting across the outboard barrier seal remains low because the small local compensating piston balances the barrier lubricant pressure to the drilling fluid pressure. This helps the barrier seal exclude abrasive drilling fluid. Second, the inboard rotary seal (BDRP® seal) operates in a clean lubricated environment. The clean lubricated
