Wellsites & Field Facilities
Equinox has designed and installed thousands of wellheads, wellhead tie-ins and wellhead flowlines, gathering systems, trunk and group lines as well as field facilities (including compression, dehydration & refrigeration). Our experience includes unconventional wellsite design with 12-18 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 & storage tanks, PSV’s, flare knock out drums and flare stacks as needed.
Standardized Designs Reduce Costs
Equinox has industry leading expertise for the development and design of multiwell pad designs for unconventional gas. We have leading edge multiwell pad designs for 4 wells, 5 wells, 6 wells, 8 wells, 12 wells and up to 18 wells per pad. By leveraging our Catalogue of Designs, clients can save as much as 75% of the engineering costs by standardizing components of the design as part of a wellsite development program.
Within this catalogue, we have complete standard design packages with templates for numerous wellsite facility configurations, including drawings (Plot Plans, BFDs, P&IDs) and documents (DBMs, PEPs, Datasheets, RFQ Descriptions & Templates, Cost Estimates). By standardizing designs, Equinox has been able to reduce engineering and procurement to as low as 1% of Total Installed Costs.
FEED & Detail Design for Montney unconventional wellpad program (each with 8 to 12 expandable wellheads. Program includes several hundred miles of sales pipelines, trunk lines and gathering lines.
A typical wellpad 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 skid (incl. communication) and chemical tanks and pumps (inhibitor and methanol).
Ojay Sour Wellsites & Dehydration Facility (30 MMscfd)
Equinox provided 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 miles of sweet fuel gas pipeline and 3 sour gas process lines.
NBC Standardized Wellsite Program
Muskeg Conventional Oil
Multi-Wellpad and Satellite Facility
Wellpads were designed with modular pipe racks such that they can be rearranged for different site orientations, expandable depending on expected flows, and quick installation due to the remoteness of the wells. This in turn reduced engineering costs as the templated design can be replicated onto future wells.
Montney Standardized Wellsite Program
Conroy, Elleh Wellsite Program
Standardization of engineering and equipment to achieve cost efficiencies with both EPCM hours and procurement streamlining. The use of a standard wellsite packages allowed for very tight cost control of engineering and allowed for consistency in capital material procurement as well as construction of sites. Equinox was successful in executing engineering for 1% of capital cost.
