摘要： There is disclosed a connector which is sometimes referred to as a pitless unit in industry for use in a pumping system including a pump, well casing, a discharge pipe to guide liquid horizontally away from the pump, and a drop pipe to guide the liquid up from the pump towards the discharge pipe. The connector acts to connect the drop pipe and discharge pipe in fluidic communication while allowing the pump therebeneath to be accessed from the surface of the ground. The connector features an outer housing and internal spool which is locatable in the housing in a seated position. An interior surface of the housing and surfaces of the spool which collectively define a chamber through which the liquid flows, when the spool is in the seated position, are weld cladded with a metallic cladding material so as to resist corrosion and erosion of these wetted surfaces of the connector.

摘要： A subsea connection system for connecting to a hub has a body with an interior passageway, a collet having a plurality of collet segments, an outer sleeve overlying the collet, and a poppet valve assembly positioned within the interior passageway of the body. The plurality of collet segments are movable between a locked position and an unlocked position. The poppet valve assembly is movable between an open position and a closed position in which the open position allows a fluid to flow through the interior passageway and the closed position blocks a flow of fluid through the interior passageway. The outer sleeve is movable so as to cause the plurality of collet segments to join to a hub.

摘要： In one system, there is an emergency pipe stroker tool, wherein the emergency pipe stroker tool is configured to act as a first mechanical barrier for a well. Further, there is an emergency quick disconnect tool in communication with the emergency pipe stroker tool, wherein the emergency quick disconnect tool comprises a connector assembly and a fluid conduit in communication with the well, and further wherein the connector assembly is configured to simultaneously detach from the well and to seal the well. Further still, there is a cement retainer in communication with the emergency quick disconnect tool and the emergency pipe stroker tool, wherein the cement retainer is configured to act as a second mechanical barrier for the well, wherein, the emergency pipe stroker tool, the emergency quick disconnect tool, and the cement retainer act in coordination to seal a well while establishing the multiple mechanical barriers.

摘要： A system for load transfer from a wellhead to the sea bed adjacent a subsea well, including a suction pile for securing to the sea bed, and a wellhead housing assembly having a longitudinal axis and attached to the suction pile, the wellhead housing for subjection to an axial load acting in a direction parallel to the longitudinal axis, and a bending load acting in a direction not parallel to the longitudinal axis. The system further includes a suction pile connector that transmits the axial load and the bending load from the wellhead housing through the suction pile toward the sea bed, and that is attached to the suction pile, the suction pile connector engaged with the wellhead housing to substantially maintain the relative positions of the wellhead housing and the suction pile.

摘要： Some examples of a packet setting method using disintegrating plug can be implemented as a method for setting a packer in a wellbore. A disintegrating plug is installed in a tubing. The disintegrating plug blocks flow through the tubing in response to pressure. A packer is installed above the disintegrating plug in the tubing. The tubing including the packer and the disintegrating plug is run into a wellbore. The packer is positioned at a wellbore location to create an annular area between the packer and the wellbore wall. Downhole pressure is applied in the tubing to set the packer.

摘要： A wellhead vault for preventing alteration of the wellhead of a water supply. The vault is a heavy bell-shaped structure, formed of concrete, and having a downwardly facing concavity, and the vault placed over, with the concavity around the wellhead. The vaults too heavy to be removed by human lifting. Lifting elements are provided to allow the vault to be installed and removed by heavy construction equipment. The vault has a vent that communicates between the concavity and the outside, allowing air, but not liquid, liquid or solid contaminants, or animals, to pass through.
