摘要： The use of an environmental sensing wireline standoff may improve operations during borehole logging procedures. An environmental sensing wireline standoff may comprise a lower body, an upper body, and a cable insert. The cable insert may further comprise a first segment and a second segment, wherein the cable insert is disposed between the lower body and the upper body, and wherein the cable insert is configurable to clamp directly onto a wireline cable. The environmental sensing wireline standoff may further comprise a sensor package. A method of assembling an environmental sensing wireline standoff may comprise securing a first segment of a cable insert into a lower body, securing a second segment of the cable insert into an upper body, attaching the sensor package to the upper body, and securing the lower body to the upper body.

摘要： A wireline standoff that may ameliorate the effects of wireline cable differential sticking, wireline cable key seating, and high cable drags by reducing or eliminating contact of the wireline cable with the borehole wall during the logging operation. An embodiment includes a wireline standoff. The wireline standoff may comprise a pair of opposing assemblies. The opposing assemblies may each comprise a half shell, a cable insert configured to be disposed in the half shell, and external fins coupled to the half shell. The wireline standoff may further comprise one or more fasteners configured to couple the opposing assemblies to one another.

摘要： The low friction wireline standoff improves wireline cable performance during borehole logging operations. The use of low friction wireline standoffs ameliorates the effects of wireline cable differential sticking, wireline cable key-seating, and high wireline cable drags, by reducing or eliminating contact of the wireline cable with the borehole wall during the logging operation. The low friction wireline standoff comprises external wheels mounted on two finned half shells that clamp onto the wireline with precision cable inserts which are manufactured to fit a wide range of logging cables. The wheels reduce the cable drag down-hole resulting in lower surface logging tensions, aiding conveyance in deep and deviated wells.

摘要： A wellbore depth instrument (WDI) for measuring wellbore depths along a wellbore, acting as an odometer. In one embodiment, the WDI may be mounted onto a downhole tool-string deployed by a pipe, coil, e-line, or slickline. Further, the WDI may comprise two independently suspended wheels of fixed diameter with respective internal electronic packages that each may record in memory rotations of their respective wheels and frequencies of those rotations along the wellbore. Such recordings may allow for accurate determination and characterization of tool-string dynamics (e.g., tool-string speed, direction, stick slip, creep and hold-ups) as well as absolute and relative tool-string position along a wellbore (i.e., wellbore depth).

摘要： The present invention relates to a wireline cased-hole standoff (WCSO) for installation on a wireline cable of a wellbore logging tool. In embodiments, WCSO may be capable of significantly reducing wireline cable drag in a cased-hole section of a well or wellbore as well as reduce logging tensions and improve force transmission from wellbore surface to logging tool cable head during wireline logging operations. In one embodiment, WCSO comprises two cable insert halves, two opposing WCSO body halves (an upper body and a lower body), and two outer shells (an upper low-friction shell and a lower low-friction shell). Such components may be fastened together onto the wireline cable using screws, bolts, dowel pins, spigots, or any combinations thereof.

摘要： 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.
