NOV Blowout Preventer (Shaffer) 18 3/4 -10M 15000 PSI

General Overview

• Type:
  • Ram-type (Shaffer design) BOP engineered for high-pressure applications.
• Nominal Size:
  • Designed to seal an 18 3/4‑inch wellbore.
• Working Pressure:
  • Rated for a maximum working pressure of 15,000 PSI, making it suitable for challenging, high-pressure drilling environments.
• Model Designation:
  • The “10M” typically indicates the specific configuration or series within NOV’s product line.

Key Specifications

• Closing Mechanism:
  • Utilizes robust rams (often in a dual- or triple-ram configuration) that generate the necessary closing force to seal the wellbore quickly and effectively.
• Materials & Construction:
  • Ramming surfaces and structural components are manufactured from high‑strength, heat‑treated alloy steel.
  • The rams are fitted with advanced friction or composite sealing materials to ensure a reliable, long-lasting seal under cyclic, high-pressure conditions.
• Seal Performance:
  • Engineered to maintain a secure seal under repetitive cycling and thermal stress, with a design optimized for rapid engagement/disengagement.
• Integration & Dimensions:
  • Designed to fit standard BOP stack configurations, with overall dimensions and mounting interfaces specified in NOV’s technical literature.
• Operating Environment:
  • Built to perform reliably in extreme downhole temperature ranges and in corrosive drilling environments.
