The facility is designed specifically for the condensate-rich gas featured in these two wells, and to meet the specifications for entry into the Dampier to Bunbury Natural Gas Pipeline (DBNGP), for which Empire has established a 20-year agreement. A 3.2 km, 102 mm diameter yellow jacket coated steel pipeline will be hot-tapped to the DBNGP, with this pipeline having the capacity to transport up to 30 terajoules (TJ) per day of sales gas, to cover future expansion.
Empire Oil and Gas Managing Director Craig Marshall says that the main challenge associated with the project so far has been the need for the facility’s design to suit the DBNGP specifications.
“Otherwise the gas and condensate is sweet, with no problematic metals, such as CO2 or hydrogen sulphide,” he explains. “As part of the condensate processing process, Empire has included a flash gas compressor and other items to ensure there are no LPGs (volatiles) in the condensate. The design is built purposely to meet both the specifications for the DBNGP and BP Kwinana Refinery.”
