Horizontal wells and multi-completion vertical wells generally have a greater performance requirement on downhole gas separators to separate a gas portion from a liquid portion of the well fluid prior to entering an artificial lifting system (or pump). Implementations described and claimed herein provide a downhole gas separator comprising a dip tube extending from a tubing inlet to an open end, a tubing section extending around the dip tube, and a separator sleeve extending around the tubing section. A liquid component of the fluid stream makes a first u-turn at the open end of the separator sleeve, an s-turn at the openings in the tubing section, and second u-turn at the open end of the dip tube. A gaseous component of the fluid stream continues upwards at the open end of the separator sleeve.

An apparatus for downhole connection of well components includes a first tubular component defining a through bore for receiving a second tubular component and a travel joint including an axially moveable inner sleeve and a coupling feature configured for coupling the second tubular component with the inner sleeve when received in the through bore of the first tubular component.

A header with associated lubricator is for fluid handling at the wellhead of an oil and gas well where a plunger/lubricator lift system is deployed, and provides a novel compact lubricator with attached header which can replace a conventional wellhead flow-tee without modifying or moving other wellhead equipment to accommodate the new lubricator and header replacing the old flow-tee. A sub seal is provided at the header/lubricator attachment(s). The header with associated lubricator encloses a conduit with seals in the attachment interfaces between the header and lubricator or between the header and exit attachment means, where the conduit may also comprise a means of flow restriction through machined geometry or by retaining a reduced diameter or valve component through various means of attachment. The flow restrictor means may also be serviced via service access means provided in the header or lubricator exterior wall.

A method and apparatus for patching damaged areas in a well includes a top and a bottom patching section which include an anchor/sealing member for securing the apparatus within the well. One or more extension patch sections are connected between the top and bottom patch sections. The top and bottom patch elements are placed above and below the damaged area to isolate the damaged area from the exterior flow portion of the well.

The articulated wireline hole finder is a modular device which attaches to the bottom of a wireline logging tool-string to aid conveyance down irregular shaped and/or deviated boreholes which possess features such as ledges, washouts, and contractions, that might otherwise terminate full descent of the tool-string to the bottom of the borehole and thereby compromise the wireline data acquisition objectives. Elements of the articulated wireline hole finder may include a low friction roller nose assembly and spacer sub, an articulated spring joint, that transfers tool-string weight and directs lateral movement of the roller nose towards hole center, and a pair of five arm centralizers that possess a wide dynamic range.
