Diverter equipment

Diverter equipment

The diverter is installed on top of the wellhead to enable flow from shallow formations to be diverted away from the work area in case of a shallow gas kick. However, current diverter equipment is not…

Subsea blowout prevention (BOP) equipment

The subsea BOP equipment may comprise either a single stack or a two-stack system. The single stack system is preferred. The single stack system consists of one large bore BOP stack (generally 18…

Classification of BOP and well control equipment.

Well control equipment falls into five basic working pressure classifications:·13,800 kPa (2000 psi) WP,·20,700 kPa (3000 psi) WP,·34,500 kPa (5000 psi) WP,·69,000 kPa (10,000 psi) WP,·103,500 kPa…
