During the development phase the gas company builds the infrastructure necessary for a fully producing gas field.
This includes using existing appraisal wells, drilling any additional production wells, building a production facility, and building flowlines and pipelines to transport the gas to market.
Sometimes the gas company can take advantage of existing infrastructure. For example, the Parmelia Pipeline was built in 1971, and all gas produced from Waitsia – Stage 1A travels to Perth via that pipeline.
This means Mitsui E&P Australia (MEPAU) only needs to build the pipes needed to connect new wells to the production facility. The production facility also needs to connect to the Parmelia Pipeline. As part of the Waitsia Stage 2 development project, MEPAU may also construct a new pipeline to the nearby Dampier Bunbury Natural Gas Pipeline.
Recent appraisal well examples include Waitsia-02, Waitsia-03, and Waitsia-04.
We are actively exploring, appraising, developing and producing oil and gas in a number of locations in the north Perth Basin. Read more about what we do
Before anything can happen we need to plan carefully. Read more about the planning process.
We look for gas, and when we find it we figure out if it’s worth pursuing further. Find out more about our exploration and appraisal process.
During the production phase we extract gas from the well and sell it. Find out more about the production process.
