Well Site & Field Facility Projects

Equinox has completed thousands of well site tie-ins and designed gathering systems, trunk and group lines as well as field facilities (including compression, dehydration, refrigeration) with ultimate transport of products to a central sour or sweet gas processing facility.

We execute hundreds of wellsite projects annually, with program sizes for single clients ranging from 3-5 sites, up to 60-70 sites in a given drilling season, with significant experience in winter access only regions.

Equinox has industry leading expertise in unconventional wellsite design with 12 to 18 wells per pad.

For wellsite tie-ins, Equinox will provide the expertise required to specify, size and utilize the appropriate equipment including separators, wet and dry meter skids, in-line heaters, condensate pump skids, methanol injection pumps and storage tanks, corrosion inhibitor pumps and storage tanks, PSV’s, flare knock out drums and flare stacks as needed.

Selected projects are highlighted below.

Montney Wellpad Development Program

Equinox recently executed full engineering and construction support services for the development of an optimized, standard wellpad design to reduce capital cost, accelerate engineering and construction schedules, and provide our client with a templated well pad design that can be replicated for future well pads. Equinox achieved a 30% reduction in the project's originally budgeted Total Installed Cost. Click to read more.

Tupper Wellsites

Concertual design through to EPCM for 600 unconventional wells. Each well pad has 1 to 12 expandable wellheads. Wells are located in Montney Zones with rates of 3.25 MMscfd per well. There are sales pipelines, trucklines and gathering lines included in this project. A typical well pad includes: a group separator (with metering package and test separator), line heaters, a temporary rental well sand separator, an HP flare stack & knock-out drum, an RTU/TEG building skid (including communication) and chemical tanks and pumps (inhibitor and methanol).



Ojay Sour Wellsites & Dehydration Facility (30 MMscfd)

FEED and Detail Design for mole sieve dehydration facility (30 MMscfd at 20% H2S, 7% CO2), as well as sour (10 MMscfd at 20% H2S) wellsites (with line heaters), along with 5 km of sweet fuel gas pipeline and 3 sour gas process lines.


South Montney – Unconventional Wellsites

FEED and Detail Design for development of over 250 wells utilizing multiwell pads, including gathering lines and trunk lines. Pad design is modular, multiwell pads expandable to 12 wells per pad.
Wells are Montney zone at an average flow rate of 3.25 MMscfd. Wellsite equipment includes: a group separator (with metering package and test separator), line heaters, sand separator, HP flare stack and flare knock out drum, RTU/TEG building
skid, chemical tanks/pumps with methanol inhibitor.


Glacier – Single & Dual Wellsites

FEED and Detail Design phase for wellsites and gathering lines; each wellpad includes single and dual wells. Wells are Doig zone at an average flow rate of 2.5 MMscfd. Wellsite equipment includes: line heater, wellhead ESD and pressure control valve, sand separator, wet metering skid, HP flare stack and knock-out drum, RTU panel, chemical tanks/pumps with methanol inhibitor, fuel gas pipeline.


South Montney – Trunklines & Gathering Lines

FEED and Detail Design for 75 km of trunklines and gathering lines. Trunklines include: 16" sour gas, 4" fuel gas and 4" source water. Gathering lines (laterals) include: 10" sour gas, 3" fuel gas and 3" source water. These projects also include 9 major river/creek crossings using HDD, pigging facilities and complete SCADA design and installation.
