Waitsia Gas Project – Stage 1

The decision to commence Stage 1 development of the Waitsia gas field was made in early January 2016 following the receipt of government and regulatory approvals.

Stage 1 comprised the installation of new infrastructure and upgrades to existing assets that connected the Waitsia-01 and Senecio-03 gas wells to Xyris Production Facility (XPF) for an extended production test. Gas processed at XPF is being delivered via an existing pipeline to the Parmelia Pipeline for domestic consumption in Western Australia.

The new infrastructure included installing two flowlines, a processing hub and a 7 km pipeline to XPF, which had been in care and maintenance since 2010.

The project required assessment and approvals from the lead agency, Department of Mines, Industry and Regulation Safety. Other approvals required by several state agencies, as well as the Shire, were also provided.

The initial capacity of XPF was approximately 10 TJ per day, with further expansion possible. First gas from the extended production test commenced in August 2016. This has provided important information about the free-flowing Waitsia gas reservoir. Well performance has consistently exceeded expectations, emphasising the excellent quality and connectivity of the conventional reservoirs in the Kingia and High Cliff Sandstones.

Development

The development phase refers to building the infrastructure necessary for a fully producing gas field.  This includes drilling and completing production wells, building a processing facility, installing interconnecting flowlines from the well heads to the processing facility and constructing a pipeline to transport the gas from the facility to customers.

Where possible, this includes using existing infrastructure.  For example, Waitsia – Stage 1 involved refurbishing the existing Xyris Production Facility, and conveying gas to Perth via the Parmelia Pipeline, which was originally built in 1971 and has since been in steady use.

Further proposed development for the Waitsia gas field includes undertaking the Stage 1 Expansion and then the Stage 2 Development.

From Discovery to Production in Less than Two Years

The Waitsia Gas Field was sending gas to the Perth market less than two years after discovery. Learn more here.
