9 Build (under-supervision) a Rope-Socket. Define and do a torture test.

Rig-up Equipment 9 Some of the Basic Equipment is also referred to as Rig-up equipment since these components allow us to ‘Rig-up’ our equipment at the Well-Site and are essential to running a Wireline operation.2

Sheave Wheels

9

Sheaves are pulley wheels with a grooved rim that allow the safe movement of the Wireline Cable from the Truck/Unit to the well. 9

Normally 2 sheaves are used in a rig-up (lower Sheave and upper Sheave) Different wheels are used depending upon the type of

36 in Upper Sheave (with no finger guard) cable used and the type of operation. 36 in Standard Sheave Wheels used in Heptacable Operations (mostly Open-Hole operations) {Shown above and below}.

(Elevator side)

Sheave Hangar: Also known as a spade is used to connect between the upper sheave wheel and the Elevator of the rig.

SLING: Safety device used to tie the Sheave hangar to the Elevators in case the elevators come open

Tie-Down Chain and Gooseneck

2

TIE-DOWN CHAIN A tie-down chain is used to anchor the lower sheave to the rig superstructure. It has 5/8-in. diameter links and is available in 10-, 20- and 30-ft. lengths.

Shackles

Gooseneck The gooseneck is used to create a smooth bending radius between the cable and tool head. This prevents cable damage at the head when lifting tools from the catwalk. The longitudinal arm prevents the gooseneck from passing through the rotary table. 8
