January 01, 2026
Witness the exceptional performance of the Shaffer Bolt-Cover Spherical Blowout Preventer (BOP) in this critical drift mandrel test. This video demonstrates how our 20 3/4"-3000psi annular BOP, manufactured to meet rigorous API 16A standards, successfully completes a drift test in under 20 minutes, immediately following its hydrostatic sealing test.

Designed for high-reliability annular pressure control in oil and gas drilling operations, the Shaffer Bolt-Cover Spherical BOP is a vital piece of well control equipment. It ensures stable sealing and pressure management during drilling, tripping, and well intervention, effectively mitigating blowout risks to protect personnel, equipment, and the environment.

Key benefits include its compact, space-saving design, efficient and cost-effective operation with low hydraulic pressure requirements, and a durable, low-maintenance construction featuring wear rings and a rugged sealing element that lasts 2-4 times longer than conventional options. Its easy servicing and field adaptability minimize downtime.
