Type:

The annular packing element, GK type, designed for BOP with tapered packing element, serves a critical function in well control during petroleum drilling operations. This tapered packing element creates a reliable seal within the BOP's annular space, preventing the uncontrolled release of fluids or gas from the well.

The tapered design of the packing element optimizes its sealing capabilities by providing uniform pressure distribution. This promotes a secure seal, even in challenging drilling conditions. The choice of materials for the packing element is crucial to ensure resilience against the harsh environments encountered in drilling operations.

Overall, the annular packing element, plays a vital role in maintaining well integrity and preventing blowouts, contributing to the safety and efficiency of drilling operations in the oil and gas industry.

Spherical packing element

National Oilwell Varco's Shaffer Spherical BOP is one of the first lines of defense in controlling a well. When actuated, hydraulic pressure operates the piston, and in turn closes the spherical. The Spherical's closure occurs in a smooth, simultaneous upward and inward motion, as opposed to horizontal motion..

Features:

Shaffer Spherical blowout preventers are compact, annular type BOPs that seal reliably on almost any shape or size kelly, drill pipe, tool joint, drill collar, casing or wireline. Sphericals also provide positive pressure control for stripping drill pipe into and out of the hole. They are available in bolted cover, wedge cover, dual wedge cover and  models that contain each of the following special features:

Rugged, reliable sealing element provides positive seal after hundreds of tests to full working pressure

Strong, simple construction; only five major parts

Compact body saves space; height is 15 to 20% less than height of some other annular BOPs

Simple hydraulic system; only two hydraulic connections are needed

Wear rings on moving parts prevent metal-to-metal contact; this feature prolongs preventer life

Suitable for H2S service. Standard models are suitable for internal H2S service, simple bolt and lifting shackle changes convert them for external H2S service

Servicing is easy; element can be changed without getting mud or grit into the hydraulic system

Steel segments reinforce sealing element but do not protrude into well bore when element is open

Element design provides long stripping life

Manufactured in accordance with API Specification 16A, Third Edition, June 2004 and NACE MR0175 per API Specification 16A, Temperature T20, Standard nitrile packing element: 40°F to 170°F
