Rig Up: Equipment Assembly, Wireline and Coiled Tubing Mobilization, and WCSB Pad Operations
To rig up means to assemble and connect all the equipment needed for an operation so it is ready to function safely and on demand. The term is used across nearly every phase of a well's life, from the initial mast and substructure erection of a drilling rig to the spotting of a workover unit, the rig-in of a wireline logging truck, the make-up of a coiled tubing spread, or the staging of a hydraulic fracturing fleet. In each case rigging up involves moving the right components onto the rig floor or location, physically connecting them, and tying them into the appropriate power sources, hydraulic circuits, and pressurized piping. For a drilling rig the sequence is large in scale: the substructure is positioned over the conductor, the mast or derrick is raised, the drawworks and crown block are aligned, the mud pumps and shale shakers are plumbed into the active mud system, the BOP stack is nippled up onto the wellhead, and the choke and kill lines are pressure tested before drilling can commence. For a smaller service operation such as a wireline run, rigging up may involve spotting the logging unit, raising a mast or rigging up a crane to hang the upper and lower sheaves, threading the cable, connecting the toolstring, and pressure testing the lubricator and grease injection head when working live wells. The common thread is readiness: nothing is run into the hole, no fluid is pumped, and no pressure is applied until the rig-up is complete and verified. In the Western Canadian Sedimentary Basin, where multi-well pad drilling on the Montney and Duvernay dominates, rig-up time is a major cost driver. A modern triple rig with walking or skidding capability rigs up once on a pad and then walks between wellheads spaced a few metres apart, eliminating repeated tear-down and rig-up cycles that historically cost operators days of nonproductive time. AER Directive 037 governs the licensing and well spacing that defines these pads, while occupational rig-up safety falls under provincial OH&S regulation and the operator's own safe work practices. Rig-up quality is checked through pre-spud and pre-job safety meetings, equipment inspection, and pressure testing, because a rushed or incomplete rig-up is a leading contributor to dropped objects, well control incidents, and pressure-related injuries. The opposite operation, rig down or rig out, reverses the process so equipment can be released and moved to the next location.
Key Takeaways
- Readiness Is the Definition: Rigging up means assembling, connecting, and powering equipment so it is fully ready before any tool goes downhole or any pressure is applied. The rig-up is not complete until every connection is made up, every line is plumbed, and the required pressure tests pass at the rated working pressure for the operation.
- Scope Spans the Whole Well Life: The term applies to drilling rigs, workover and service rigs, wireline and slickline units, coiled tubing spreads, snubbing units, and frac fleets. Each rig-up has its own checklist, but all share the same goal of staging equipment that is mechanically sound and safely tied into power and pressure systems.
- Pad Drilling Slashes Rig-Up Cycles: Walking and skidding rigs on WCSB Montney and Duvernay pads rig up once, then move between closely spaced wellheads under their own power. This eliminates the repeated rig-up and tear-down that once cost operators multiple days of nonproductive time per well on single-well leases.
- Pressure Testing Gates Live Work: Any rig-up for live-well service, including wireline lubricators, coiled tubing, and snubbing, requires pressure testing of the surface assembly before the well is opened. AER Directive 037 and provincial OH&S rules, along with operator safe work practices, set the framework for verification before work begins.
- Rig-Up Time Drives Cost: Day rates for drilling and service equipment accrue from the moment the spread mobilizes, so rig-up hours are billable nonproductive time until the bit turns or the tool runs. Efficient, well-rehearsed rig-up procedures directly reduce the all-in cost of a well or intervention in CAD per operating day.
Drilling Rig-Up Sequence on a WCSB Pad
A triple drilling rig rigging up on a Montney pad near Dawson Creek follows a strict order. The substructure and matting boards are set, the mast is raised hydraulically, then the drawworks, top drive, and rotary equipment are aligned. Mud pumps are tied into the active pit system, shakers and the degasser are plumbed, and the BOP stack is nippled up on the wellhead and function tested. Choke and kill manifolds are connected and pressure tested to the rated working pressure, often 35,000 kPa (about 5,075 psi) for these wells. A full pad rig-up for a walking rig can run 36 to 72 hours at day rates of CAD 28,000 to CAD 45,000, so crews rehearse the sequence to compress the timeline.
Wireline and Coiled Tubing Rig-In on Live Wells
Service rig-ups on producing wells add a pressure-control dimension. A wireline crew rigging in to run a production log spots the unit, rigs up a mast or crane to hang the sheaves, then makes up a lubricator long enough to contain the toolstring above a closed wellhead valve. The lubricator, grease head, and BOP are pressure tested to above the anticipated wellhead pressure before the well is opened. A coiled tubing rig-up adds the injector head, reel, power pack, and a quad-BOP stack, all hydraulically connected and tested. On Duvernay and Montney wells with shut-in pressures near 20,000 to 30,000 kPa, a faulty rig-up means a containment failure, so every connection is logged on a pre-job pressure test record.
Fast Facts
The shift from single-well rig-ups to multi-well pad rig-ups transformed WCSB economics. On a single-well Cardium lease in the 1990s, an operator paid for a full rig-up and tear-down per well, often two to four days of rig time each way. A modern eight-well Montney pad rigs up the drilling rig only once, then the rig walks between cellars on rails, completing all eight wells before rigging down. That single change can save an operator more than 20 days of cumulative rig-up time across one pad, worth several hundred thousand dollars in avoided day-rate charges.

Rigging up is the staging step before a run, since no logging tool or drill string enters the hole until the rig-up is verified. It is the inverse of rig down, the tear-down that releases equipment for the next move. A complete rig-up includes nippling up the blowout preventer stack, the primary well-control barrier, and on producing wells it depends on the wellhead valves that isolate pressure while surface equipment is assembled and tested. Each of these connects directly to the integrity of the finished rig-up.
Real-World WCSB Scenario: Pad Rig-Up Near Grande Prairie
An operator developing a six-well Montney pad northwest of Grande Prairie contracted a walking triple at a CAD 38,000 day rate. The crew completed the full rig-up, including mast raising, mud system tie-in, and BOP nipple-up with a 35,000 kPa pressure test, in 41 hours. Because the rig could walk between wellheads on its skid system, no further full rig-ups were needed across the remaining five wells, only short repositioning moves of under four hours each.
Over the six-well program, the single shared rig-up versus six separate rig-ups saved an estimated 16 rig days, roughly CAD 608,000 in avoided day-rate charges, and removed dozens of high-risk mast-raising and crane lifts from the schedule. The economics of pad rig-up are now central to how WCSB unconventional plays are developed.
