Amplitude Versus Offset (AVO) Analysis of Kipper and Golden Beach Gas Sands indicates significant additional gas play across the Vic/P47 Permit & Judith Gas Field

Key Points

Emperor Energy is pleased to advise of the very strong results achieved from recent Amplitude Versus Offset (AVO) analysis of the Golden Beach and Kipper Gas Sand formations using the final, fully processed 3D PSDM seismic data received from international seismic acquisition company CGG in November 2021.

The fully processed seismic data allows for a significantly better seismic evaluation of the section above the Judith Gas Sands and also provides the best clarity and definition of AVO response yet seen across the Judith structure and gas field.

The AVO analysis was carried out across four geological sequences as follows:

1. Kipper Sandstone
2. Upper Golden Beach Sequence
3. Lower Golden Beach Sequence
4. Basal Golden Beach Sandstone

onlyThe geological sequences and AVO attributes were correlated and tied back to Reservoir gas in the Kipper-1 well representing the currently producing Kipper Gas Field operated by Exxon Mobil.

AVO response is used as a Direct Hydrocarbon Indicator (DHI). Three types of AVO attribute analysis were carried out as follows:

1. AVO Gas Indicator
2. AVO Class III (Gradient vs Intercept cross-plot)
3. Shuey Fluid Factor

useHigh AVO values indicate the presence of reservoir gas in the Kipper Sandstone and on three additional sequences of the underlying Golden Beach Sub-group.

personalThe extent of the strong AVO response is interpreted to indicate potential gas saturation in these sands extending over more than 500m of vertical relief across the Judith structure terminated by the Rosedale Fault to the north.

2. Rock Volume Calculations leading to Prospective Resource Upgrade

The fully processed seismic PSDM 3D Seismic Data has allowed a significantly better seismic evaluation of the onlyKipper and Golden Beach gas sands above the Judith Gas Sands. This has not been previously possible on the older

vintage seismic.

The very strong AVO response within the Kipper and Golden Beach gas sands and correlation of the AVO response to the Kipper-1 well indicates that the sands are highly prospective for gas and a possible extension of the Kipper gas field into Vic/P47.

The top seal of this play is interpreted as the overlying Campanian Volcanics with the Rosedale Fault providing the useup-dip lateral seal.

Initial calculations of rock volumes indicate the four gas sand intervals have the potential to contain significant Gas in Place. Emperor Energy is now progressing Gas in Place calculations and preparing an upgrade of Prospective Resources within the Vic/P47 Permit.

3. Judith Gas Project Objective

personalEmperor Energy's key focus is the development of the Judith Gas Project located 40km offshore from the Orbost Gas Plant in the Gippsland Basin, Victoria (Figure 4). Based on the existing P50 Unrisked Prospective Gas Resource of

1.226 Tcf within the Vic/P47 Permit area, the project objective is to establish a sales gas capacity of 80TJ per day equivalent to 28PJ per year over a minimum production period of 15 years with the value of gas and condensate sales exceeding $A300M per year based on AEMO mid-range pricing forecasts.
