The invention comprises an activator ring and locking ring usable to connect a variety of parts used in oil and gas field production operations. The invention further comprises connection elements integrated into oil and gas well pipeline parts, such as washing tools, pack off bodies, mandrel casing hangers and other pipeline parts to permit simplified and secure connections to improve well head operations. The oil and gas field parts and activator ring use a novel design for tabs, slots and fixing devices to secure the connection of production parts in the well head. The design allows simpler and safer connections of oil field equipment components.

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.

A power slip extends a joint from tubing disposed in casing at a well so that a casing head can install on the casing and the tubing can be packed-off from the casing. The joint attaches to an inner sleeve having collet members that fit onto the inner tubing so that the joint extends thereabove. An outer sleeve and interlocking collet assemble together and install onto the inner sleeve. The collet threads onto the inner sleeve and forces the outer sleeve downward onto the inner sleeve. Being forced, the outer sleeve causes the collet members to engage around the inner tubing. The casing head then installs on the casing with the joint extending up through the head's bowl. An H-plate installs in the open bowl around the extended joint, and another pack-off installs on the joint to pack it off from a spool attaching to the casing head.

A safety valve apparatus has a housing with a bore and a projection in the bore. A flapper rotatably disposed on the housing is movable relative to the bore between opened and closed positions, and a packing element disposed on the housing is compressible to engage an inner conduit wall surrounding the housing. An upper sleeve disposed within the bore above the projection is hydraulically movable from a first position to a second position via the hydraulic communication with a port in the projection. The first sleeve when moved to the second position compresses the packing element. A piston disposed in the housing hydraulically communicates with the port and couples to a second sleeve disposed within the bore below the projection. The second sleeve conceals the piston and is hydraulically movable via the hydraulic communication of the port with the piston to open and close the flapper.

A spray system is provided for distributing fluid over a selected area through a distribution header to spray units. A control unit uses a siphon loop to continuously cycle an internal water level between two elevations. A water level float provides an output for actuating a valve effective to vary fluid pressure in the distribution header and affect a sweeping of the spray produced by the spray units. The fill rate of the control unit may be varied to change the sweeping rate of the spray through the spray units.
