Self-aligning hanger and centralizing features increase casing and tubing hanger landing reliability, while the hangers and packoffs are designed with angled shoulders to repel debris, such as dirt, metal shavings and cement plugs.

Extreme Operating Conditions

Cameron SOLIDrill modular compact wellhead systems are capable of being used on land or offshore. The flexible design reduces lead times and inventory costs. They are rated for severe service conditions, including pressures up to 10,000 psi.

Increases Safety and Efficiency

The wellhead is designed to reduce exposure to potential open-hole and lost-time incidents. This is achieved by reducing the number of BOP connections, wellhead penetrations (no lock screws) and through-BOP or -diverter operations.

Impedes Hanger Tilt

The SOLIDrill system is constructed with substantially more socketing and guides the casing within set boundaries. This helps mitigate wedging problems when pressure is applied and reduces the possibility of hanger tilt.

The wellhead is installed on its own dedicated landing shoulder, eliminating the need to look through upper outlets to ensure full land-out. A lock ring alleviates the potential for hanger lift during casing cementing. It also acts as an optional temporary lockdown mechanism for landing casing hangers.

Operational Flexibility

Versatility eliminates excessive use of costly customized equipment. The SOLIDrill wellhead accommodates different casing programs with a single system and minimal tooling. It also accommodates a wide range of tubing programs, including single and dual completions with an ESP cable penetrator. The tubing hanger and running tool assembly are assembled and tested offline. This facilitates installation and testing of all control lines, as that can be done without breaking the connection.

Running procedures are standardized, and technician competency is managed through training and regulated learning. The SOLIDrill system meets API 6A standards. It can be configured in two- or three-stage arrangements, and is available in 11 inches and 13 5/8 inches.
