The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the legs are held in place by cans embedded in the sea floor to resist lateral movement of the rig and the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration.

The present invention is directed to methods for controlling the operations of a well service rig at a well site by evaluating load sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and an average rig load can be determined for each pull of tubing or rods from a well. The average rig load can be used to calculate and set a rig overload level. If the rig load sensor reads a rig load at or above the rig overload level, the clutch for the hoist can be disengaged and the brake applied to prevent the load from either damaging the rig or breaking off the tubing or rods in the well. In addition, the rig load can be evaluated to determine when the limit the block speed when pulling rods or tubing.

To deploy a capillary string through a wellhead to a downhole safety valve, a control port and a retention port are drilled in an adapter between a casing hanger and a gate valve or elsewhere. The capillary string is connected to a first port of a capillary hanger and installed through the wellhead. The capillary hanger is landed on a tubing hanger, and a side port on the capillary hanger communicates with the control port. Because the side port's location may not align with the control port, operators may need to measure how long the capillary hanger should be. A control line connects to the control port in the wellhead's side to communicate with the capillary line, and a retention rod inserts in the retention port to support the capillary hanger. 1.

Принадлежит: Gulfstream Services Inc

A method of evacuating hydrocarbons from a plurality of nested tubulars of a well pipe that extends from an underwater well tree includes an initial step of attaching a fluid transmission line to the underwater well tree, the fluid transmission line having one end portion forming the attachment to the tree and the other end portion attached to a pump that forces fluid under pressure to the tree and attached nested tubulars. Openings are formed through one or more tubulars of the nested tubulars at a selected location. A specially configured fitting is attached to the tubulars. The fitting seals the openings. The fitting has an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, pulling a tapered mandrel against the seal. The saddle surrounds the mandrel and bears against an outer tubular of the nested tubulars. The fitting mandrel has a bore. Hydrocarbons escape from the tubulars via the mandrel bore.
