3D Seismic exploration RL top of seam RMS Amplitude UCG Panel Amplitude Anomaly Over UCG cavity After Peters T, Rich N, Strong S, 2010 Seismic reflection: A useful tool to assist UCG Proceedings of the Bowen Basin Geologist s Group Conference October 2010
Detail of 3D Seismic Survey RMS Amplitude anomaly over UCG cavity Design cavity Monitoring wells The anomaly is centered on the UCG cavity, but does not show edges precisely
Water Monitoring Bloodwood Creek Over 50 monitoring devices in 30 water monitoring bores within an area of less than ½ square mile Monitor: - Water Quality - Groundwater Pressure - Gas Composition - Microseismic signals - Temperature 3 monitoring layers provide security in controlling the gasification process, maintaining operational parameters and preserving groundwater quality 12
Queensland resources Interest in 2,000 km2 of EPC s but drilled only small part 668 Mt 450 Mt Inferred 218 Mt indicated (2m cut-off) JORC compliant coal 13
JORC practice Proven ore Reserves (Recovery plan) Measured mineral resource <250m <1km Indicated mineral resource 4km Cutoffs for grades and thickness Inferred mineral resource
Petroleum Resources Management System RESERVES Discovered petroleum In place commercial subcommercial 1P 2P 3P Proven Probable Possible Contingent resources 1C 2C 3C Other undiscovered and unrecoverable classes
UCG Reserves Certification Independent certification MHA Petroleum Consultants for EPC 867 and EPC 869 In accordance with Society of Petroleum Engineers (SPE) guidelines the reserves are: Area Category Gross Gas PJ Bloodwood Creek 1P Reserve (proven) 11.0 EPC 867 including 2P Reserve (proven + probable 743.9 MDL 374 3P Reserve (proven + probable+ possible) 1042.8 Additional resources 2C (Contingent) of 1927.7 PJ have also been identified in both Bloodwood Creek EPC867 and Kogan EPC 869 areas
Key criteria- PRMS assessment Coal resource base is JORC 1P 2P 3P resource based on seams >5m 2C resource based on seams >2m Active production requirement Syngas and energy produced per tonne coal gasified Percentage of coal accessed by UCG required 1P only for existing UCG panel +2 Commercial requirement Must have offtake/sales contract Significant discount for UCG from 17300PJ insitu in coal to PRMS syngas 2P of 744PJ and 3P 1043PJ + 2C 1928PJ
