| A well casing has a boxlike adapter extension projecting laterally therefrom and there is a tubular nipple extending through an upright wall of the box above the bottom thereof, the nipple carrying an enlarged stainless steel bearing face within the wall of the adapter box which bearing face is provided with integral guideways at opposite sides thereof for receiving a wedge block projecting from a bronze T-fitting, said T-fitting and wedge block having a lateral passageway registrable with the opening of the nipple. The guideways are open at the bottom to allow the lower edge of the wedge block to project a short distance therethrough so that the ends of said lower edge contact the arcuate bottom wall of the adapter box when the wedge block is in operative position with respect to the nipple. Thus the load is carried by the bottom wall of the adapter box rather than by the guideway of the nipple. The nipple and guideway are of stainless steel to prevent electrolytic action and the wedge and guideways provide for a fast sealing engagement at the end of the insertion.

| A DISTRIBUTION UNIT FOR USE WITHIN A WELL CASING OF A PITLESS WELL INSTALLATION SERVES TO ESTABLISH A PRESSURE ISOLATED CHAMBER INTERCOMMUNICATING THE DROP PIPE OF THE WELL WITH A LATERAL DISCHARGE OUTLET. THE UNIT INCLUDES A PAIR OF END SUPPORTS HELD IN SPACED RELATION BY A PERFORATED CONDUIT, EACH SUPPORT CARRYING A PACKER ENGAGEABLE IN SEALING RELATION WITH THE WELL CASING. ONE END SUPPORT IS ENGAGEABLE WITH A HANGER PIPE FOR SUSPENDING THE UNIT AT THE LEVEL OF THE DISCHARGE OUTLET, AND THE OTHER END SUPPORT IS ENGAGEABLE WITH THE DROP PIPE FOR INTRODUCING FLUID THROUGH THE CONDUIT PERFORATIONS INTO THE CHAMBER DEFINED BETWEEN THE PACKERS. EACH PACKER INCLUDES A FLEXIBLE RESILIENT SLEEVE EXPANDABLE INTO SEALING ENGAGEMENT AGAINST THE CASING WALL WHEN THE CHAMBER IS SUBJECTED TO PRESSURE, TOGETHER WITH AN OUTER RIB STRUCTURE PROVIDING A SEAL WHEN THE CHAMBER IS SUBJECTED TO VACUUM.

| 203 | Pitless well adapter | US3556213D | 1969-08-26 | US3556213A | 1971-01-19 | KRAMER DEAN C |
| A pitless well adapter comprises an elongate body having a fitting in its lower end for connection to the well pipe and having a fitting at the upper end for connection to a pull pipe. The body has two end flanges and a central flange, and the exterior surface between these flanges presents two tapered portions. One tapered portion flares downwardly and outwardly from the upper end flange, while the other tapered portion flares downwardly and outwardly from the central flange. When the adapter is installed, O-ring seals will roll along the flared surfaces and seat within grooves, so that the adapter is mounted in sealed relation within the well casing.

| 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. | ||||||

| Support systems, apparatus and methods for use with well structures, which may be used to reduce the cost and/or risk of performing procedures on assets, for example, prior to or during well abandonment. A support system includes an actuation system for use with a support member. The support member may be configured for complementary engagement with the actuation system. A cross-over section is configured for use at a lower end of the support member and includes a body portion and a well structure portion. The bore of the cross-over section changes from a first diameter at the body portion to a second diameter at the well structure portion, the second diameter being greater than the first diameter. | ||||||

| 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. | ||||||
