Farrell Creek Sweet Gas Production Facility

Farrell-Creek-Sweet

Capital Cost:

$10.5 MM

The Mandate:

The proposed gas plant will be used to process gas from a sweet Montney gas zone that will be developed in the same area as the proposed gas production facility. Sweet gas from the well sites will be wet metered and brought into the facility along with any production liquids for processing. The sweet gas will be compressed and processed through a dew-point control skid (either dehy or refrige) and then metered before discharging into an existing Spectra Energy sweet gas sales pipeline. The produced water will be injected into a disposal well and any hydrocarbon liquids will be trucked from site and sold at a nearby sales terminal

The Solution:

GRB constructed and commissioned a sweet gas production facility in the Farrell Creek area of NE British Columbia.  This grass roots sweet service facility consisted of the following installations:

  • Inlet riser area complete with pig receivers and common inlet header
  • 3 phase horizontal inlet separator sized for a capacity of 50 MMSCFD of gas
  • 2 stage reciprocating compressor with a capacity of 12.5 MMSCFD of gas with infrastructure in place to increase total compression capacity up to 50 MMSCFD of gas with the addition of three (3) compressors of similar size
  • Dehydration package for dew point control sized for a capacity of 25 MMSCFD of gas with infrastructure in place to increase dehydration capacity to 50 MMSCFD of gas with addition of one (1) similar sized unit
  • Sales gas meter station operated by Spectra with H2S analyzer, gas chromatograph, water cut analyzer and a sonic meter run with a capacity of 50 MMSCFD of gas. The ability to switch out the sonic meter run for a larger size  to increase the capacity to 100 MMSCFD of gas
  • Outlet riser with provisions for future pig launcher and 10" diameter pipeline to tie-in the production facility into a Spectra sales gas pipeline
  • Two (2) 400 barrel storage tank for free liquids
  • Site power provided by a 190 kW natural gas driven generator package
  • On site instruments work on instrument air to be provided by an on-lease instrument air compressor package
  • Multi-well gathering system c/w with wellsite metering and SCADA data transmission and control.
