The Red Gully Gas and Processing Facility is the first dedicated gas and condensate rich processing facility constructed in the Onshore Perth Basin to treat Jurassic aged gas.
It will treat the Gingin West-1 and Red Gully-1 gas
and condensate to the specification required for entry into the DBNGP and the
BP Kwinana Refinery.
The initial facility design will treat up to 10 million cubic feet of gas
per day (MMcf/d) and up to 500 barrels of condensate per day. There is
provision for future expansion of the Processing Facility to process up to 20
MMcf/d of gas and 1,600 bbl/d of condensate.
A 3.2km export pipeline from the Facility is tied into the Dampier to
Bunbury Natural Gas Pipeline (DBNGP) using the ‘Hot Tap’ process. This makes
provision to provide the State with much needed domestic gas supplies. Empire
has established a 20-year agreement for the use of the DBNGP.
A Gas Sales Agreement was finalised with Alcoa of Australia in 2011 and a
contract with BP in 2013.
The Facility required a complex design to separate the condensate from the
gas. Additionally, the gas must meet specifications to enter the DGNBP for sale
to Alcoa (and others in future) and condensate must meet the specification for
refining at the BP Kwinana Refinery.
Specialist equipment including the Flash Gas compressor and Export Compressor
were manufactured by Enerflex in Houston. Local contractors and consultant were
used wherever and whenever possible.
The two back-to-back discovery wells connected to the Facility boast the
largest gas flow rate from an onshore well in the Perth Basin. Gingin West-1
flowed at a stabilised rate of 7.5 million cubic feet per day (MMcf/d) of gas
and 375 barrels per day (bbl/d) of condensate. Red Gully-1 flowed at a
stabilised rate of 12 MMcf/d of gas and 832 bbl/d of Condensate.

Prospects in the nearby Wannamal and Gingin Gas Field Areas have the
potential to trap recoverable gas of up to 205 billion cubic feet and 9.2
million barrels of condensate. These areas are currently part of the Wannamal
3D Heliportable Seismic Survey being undertaken adjacent to the Facility.
the survey is complete (June 2013), the prospects will be ranked for drilling
to find additional reserves for the Red Gully Gas Facility. Drilling is
scheduled for 2014.
