Surat Basin Operations Update

Pipeline inspections

Shell’s QGC business operators work in small teams to inspect the 543 kilometre Wallumbilla Gladstone Pipeline easement to monitor the infrastructure and progress of vegetation rehabilitation. The Wallumbilla Gladstone Pipeline is a high-pressure transmission pipeline connecting the gas fields in the Surat Basin to our LNG plant on Curtis Island. Activities in the second half of 2021 include:

1. Aerial inspections using a helicopter from west of Dalby (Ruby Jo site) to west of Wandoan (Woleebee Creek site) and between Chinchilla and Gladstone. This occurs every six weeks.
   
2. Regular easement inspections from west of Dalby (Ruby Jo) to Wandoan (Woleebee Creek) and Gladstone (Curtis Island).

Goondooloo

The next campaign of wells for Shell’s QGC business is Project Goondooloo located in the same Surat Basin, Queensland area also including about 250 wells and connected to our existing facilities that supply natural gas to domestic and export customers. The project commenced drilling April 2020 with 93 wells drilled by the end of June 2021. There is a Northern Area camp being built which will reduce the amount of traffic on the areas roads traveling from the main camps to site.

The Northern Water Treatment Plant, at Woleebee Creek south-west of Wandoan, and the Kenya Water Treatment Plant, south-west of Chinchilla, are successfully processing water produced in the surrounding gas fields for beneficial use within these regions. These two water treatment plants enable QGC to make most of the raw coal seam gas water processed at each plant available for beneficial use. The following table summarises the average daily production at each water treatment plant and the total volume of water processed to date.
