Carpentaria-2H Generates Strong Initial Gas Flow Rates
Carpentaria-2H Generates Strong Initial Gas Flow Rates

Sydney, Aug 11, 2022 AEST (ABN Newswire) - Empire Energy Group Ltd (ASX:EEG) (EEGUF:OTCMKTS) is pleased to provide shareholders with an update regarding the ongoing flow testing of the Carpentaria-2H ("C-2H") well in Empire's 100% owned and operated EP187 tenement, located in the Northern Territory's Beetaloo Sub-basin.

Fluid flowback from C-2H has progressed, with 27.8 per cent of placed fluids recovered to date and water rates declining as the well continues to "clean up". It is particularly encouraging that C-2H was able to "clean up" (i.e. lift the injected fluids through the well bore to surface) through 4 1/2" casing without the need for installation of smaller diameter 2 7/8" production tubing or any artificial lift assistance such as nitrogen enhancement.

Gas flow from C-2H commenced on 5 August 2022 at significant but unmeasurable rates due to slug flow. Measured gas flow commenced at 10am on 7 August 2022 and has stabilised at an average rate of 2.6 mmscf per day across the stimulated horizontal section of 927 metres (a normalised rate of 2.8 mmscf per day per 1,000 metres) with minimal decline in production rate seen to date over the first 91 hours. The well is currently flowing at 2.5 mmscf per day.

Empire successfully placed 6,283,200 pounds of proppant across the 927 metre (3,041 foot) stimulated horizontal section, representing proppant concentration of 2,066 pounds per foot.

As previously announced, Empire is testing four different fluid systems. The trialling of systems included the successful placement of seven slickwater stages without 'screening out' which represents a first for any operator in the Beetaloo Sub-basin. Slickwater stimulation fluids may have significant positive cost reduction benefits in a future development scenario.

Empire expects that there will be differing rates of production across the 21 stages because of the fluid systems and perforation strategies tested, which will be determined by 11 gas tracers and 17 water tracers that have been placed across the C-2H horizontal section. Empire is collecting gas and water samples for gas composition and stage contribution analysis. The technical data collected will assist Empire with future completion design to drive optimised well production performance. Empire intends to apply the most productive system(s) when stimulating the Carpentaria-3H well to be drilled later in 2022.

Flow testing continues at C-2H.

Comments from Managing Director Alex Underwood:

"This is an outstanding result for Empire and our shareholders, and a historic moment in the advancement of the Beetaloo Basin. To our knowledge, this is the highest sustained gas flow rate of any well drilled in the Beetaloo Basin to date.

As previously announced, the primary goal of the Carpentaria-2H stimulation and flow testing program is not to achieve maximum flow rates but rather to assess which of the four fluid systems trialed (crosslink, HVFR, hybrid and slickwater) is likely to provide the best production performance in the Beetaloo Basin's shales and to optimise our completion methodology. Our successful stimulation of 21 stages using these various fluid systems and the placement of the entire planned quantity of proppant in those stages was a crucial first step.

Since then, strong and stable gas production rates, coupled with slowing water production, have given the Empire team enhanced confidence that we are rapidly approaching demonstration that the project is commercially viable, particularly given the significant cost advantage compared to other parts of the basin.

We don't yet know which of the 21 stages is giving us the strongest production rates, and therefore which fluid system will drive optimal production and cost performance in development scenarios. We will gather and analyse this data in the coming weeks and months. However, our preliminary view is that it is highly likely that some stages are generating more production than others.

These learnings, to be incorporated into our completion design for Carpentaria-3H, are likely to drive even stronger production rates in that well and future wells, consistent with the learning curves that were achieved across the major US shale basins.

Thank you to our team and shareholders for your support. I look forward to providing further updates as C-2H flow testing continues and we commence the next phases of the 2022 program."
