| 221 | Methods and systems for subterranean multilateral well drilling and completion | US296941 | 1994-08-26 | US5564503A | 1996-10-15 | James R. Longbottom; Don C. Cox; John C. Gano; William R. Welch; Pat M. White |
| Improved methods and systems for creating a multilateral well and improved multilateral well structures. In one aspect of the present invention, the method comprises the steps of: (1) setting a diverter at a prescribed position and a prescribed orientation in a main well flow conductor located within a main wellbore, (2) boring through a sidewall of the main well flow conductor and into a material surrounding the main well flow conductor, the boring creating a window having a particular shape in the sidewall, the orientation of the diverter determining a lateral position of the window in the main well flow conductor, a lateral wellbore thereby being formed in the material and extending from the main wellbore, (3) lining the lateral wellbore with a liner, the liner having an interface end, the interface end adapted to contact a periphery of the window in the sidewall and (4) cementing the liner in place within the lateral wellbore, the step of cementing creating a pressure-bearing seal between the periphery of the window and the interface end of the liner. The method allows multiple lateral wellbores to be joined to the main wellbore and provides for connectivity among main and lateral wellbores, pressure-bearing sealing of joints to allow selective isolation of one or more wellbores or portions thereof and subsequent wellbore access for rework or other purposes. | ||||||

| A well flow conductor and method of manufacture therefor. The well flow conductor includes: (1) a composite liner tube composed of a plurality of overlapping, resin-bonded composite plies and adapted to conduct a fluid flow therethrough and (2) a composite outer structure surrounding the composite liner tube and composed of a plurality of overlapping, resin-bonded composite plies arranged in a plurality of opposed helices about a centerline of the composite liner tube, the opposed helices intersecting at predetermined axial and radial locations on an outer surface of the composite liner tube to form nodes extending radially outwardly from the outer surface to form standoffs therefrom, the standoffs capable of centralizing the well flow conductor within an interior of a casing having a larger radius than that of the well flow conductor. | ||||||
| 224 | Torque-resistant, seal setting force-limited, hydraulically settable well packer structure and associated methods | US380901 | 1995-01-30 | US5501281A | 1996-03-26 | Pat M. White; John C. Gano |
| A torque-resistant hydraulically settable packer is coaxially positionable within a subterranean well flow conductor and has a tubular body that carries a circumferentially spaced series of radially outwardly movable slip anchors having, on outer side surfaces thereof, gripping teeth with lengths that are sloped relative to the longitudinal axis of the tubular and to a plane perpendicular. Inner side surfaces of the slip anchors are engaged by circumferentially spaced flat outer side surface areas formed on the facing frustroconical ends of an opposed pair of annular setting wedge members coaxially carried by the tubular body and being axially drivable to radially outwardly shift the slip anchors to their setting positions. As the slip anchors are being set, an annular resilient seal structure is simultaneously compressed in an axial direction against a setting force limiting member telescopingly received in one of the setting wedge members, and radially deformed outwardly into sealing engagement with the interior side surface of the well flow conductor. After the slip anchors are set, the seal structure is further compressed in an axial direction by hydraulically shifting the tubular body relative to the slip anchors. If this subsequent axial compression force exerted on the seal structure is above a predetermined maximum level the setting force member is wedgingly driven into its associated setting wedge member to limit the total axial compression force imposed on the seal structure. | ||||||

| A support device for running at least one flexible elongate member, such as a cable, pipe or the like, from a fixed station to a station movable with respect to the fixed station provides an open-ended loop region between the fixed and movable stations. It includes a guide strip defining a path for the member. The relaxed cross-section of the guide strip has a curved profile providing longitudinal stiffening to resist bending of the strip away from its longitudinal axis. The strip is elastically deformable, however, to assume a flattened cross-section in the loop region. In an open form of device, the elongate members are held on to the strip by spaced clips or elastic bands. In a closed form of device the elongate members are held in a space between the guide strip and an auxiliary guide strip running along it. In this closed form, seals may be provided along the mating edges of the strips, and spacers may be included in the member-receiving space between the strips for locating the member or members. A drum may be arranged to lie loosely in the loop. The guide strip may be arcuate or undulant in cross section.

| 240 | Method and system for transporting oil by pipe line | US3650119D | 1970-04-02 | US3650119A | 1972-03-21 | SPARLING JOSEPH T |
| System and method for transporting oil by pipe line under or over frozen ground, e.g., permanently frozen terrain, without melting or softening the ground by heat transfer from the oil, by passing oil through a pipe line supported by such frozen ground or terrain, placing a second pipe line for carrying a fluid refrigerant, particularly liquid natural gas, along and closely adjacent to the oil pipe line but spaced therefrom, the second pipe line also being supported by the frozen ground, and being disposed adjacent to the frozen ground, providing insulation between the oil and refrigerant, e.g., liquid natural gas, pipe lines, as by placing the oil pipe line in an excavation in the ground and positioning the liquid natural gas pipe line in such excavation below and parallel to the oil pipe line, with gravel, for example, filling the spaces in the excavation and between the two pipe lines, passing a liquid refrigerant such as liquid natural gas through the second pipe line at a temperature substantially below the temperature of the adjacent frozen ground, thereby maintaining the ground around the pipe lines frozen without cooling the oil in the oil pipe line down to a temperature which substantially retards flow of the oil in the oil pipe line. As a feature of the invention, a minor portion of the liquid natural gas at each pumping station can be used for operating both the oil pump or pumps and liquid natural gas pump or pumps at the respective stations. The result is that the ground supporting or surrounding the oil pipe line remains in permanently frozen condition to firmly support such pipe line at all times, and at the same time liquid natural gas can be transported to market and a portion thereof employed to operate the pumping stations.
