Feasibility Study for a Southern Surat project

Project Summary

A feasibility study was undertaken to deliver sufficient scientific and operational information to assess the suitability of the South Surat Basin as a reservoir for CO₂ Storage. The report also includes a proposal to drill one (1) well and carry out a limited 3D seismic survey surrounding the well within the EPQ10 tenement to collect essential geological, water quality and geophysical data to enable many of the R&D projects.

The scientific (R&D) component of the proposed EPQ10 project has been designed to address the following key research objectives that impact on the pathway to industrial-scale geosequestration in the Southern Surat Carbon Capture and Storage (CCS) Hub:

• Regional storage capacity for EPQ10 including storage efficiency (and maximisation) within the Precipice Sandstone.
• Plume monitoring and verification for injection options.
• Cost-effective field operations including low-cost monitoring and verification wells for deployment at industrial-scale.

The suite of potential activities listed include plume modelling, injection experimental design and geochemistry projects focussing on R&D associated principally with the maximisation of pore space for efficient CO₂ storage.

The operational component of the proposed EPQ10 project has been devised to achieve the following three key objectives:

• Provide an early and cost-effective go/no-go decision on the suitability of the Southern region of EPQ10 for industrial-scale CO₂ storage through the timely drilling, coring and logging of the Precipice Sandstone and adjacent formations.
• Provide geophysics, formation and water data to enable much of the proposed Scientific Program.
• Deliver well and site infrastructure for subsequent CO₂ injection testing that potentially provides some of the foundation infrastructure for later conversion of the site to an industrial-scale CO₂ storage complex.
