Abstract
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.
Claims16
A wireline assembly, comprising:
- a wireline cable;
- ajar, and
- one or more wireline standoffs located on the wireline cable above the jar, wherein each of the one or more wireline standoffs comprises a cable insert disposed between a pair of opposing assemblies, and wherein the cable insert comprises an anti-rotation spigot.
A method of reducing cable friction above ajar of a wireline assembly, comprising:
- providing a wireline assembly comprising a wireline cable and ajar,
- securing one or more wireline standoffs to the wireline cable above the jar, wherein each of the one or more wireline standoffs comprises a cable insert disposed between a pair of opposing assemblies, and wherein the cable insert comprises an anti-rotation spigot;
- conveying the wireline assembly into a borehole;
- and
- reducing a cable friction caused by the wireline cable contacting a wall of the borehole,
- wherein the reducing results from the one or more wireline standoffs lowering an area of contact between the wireline cable and the wall of the borehole.
A method of assembling a wireline assembly, comprising:
- a. disposing a wireline assembly comprising a wireline cable and ajar into a borehole;
- b. placing two parts of a cable insert around the wireline cable at a location above the jar, wherein the cable insert comprises an anti-rotation spigot;
- c. securing the two parts of the cable insert to each other;
- d. placing a pair of opposing assemblies around the cable insert;
- e. securing the pair of opposing assemblies to each other, and
- f. repeating steps (b) through (f) at a different location on the wireline cable above the jar.
