Northern Territory EP187 Seismic Results

Sydney, Jan 23, 2020 AEST (ABN Newswire) - Empire Energy Group Limited (googlechartASX:EEG) (googlechartEEGUF:OTCMKTS) is pleased to announce the completion of processing and interpretation of the recently acquired (231-line kilometres) 2D seismic data set in its 100% owned Northern Territory (NT) EP187 permit, across the eastern sector of the Beetaloo Sub-Basin. The seismic data confirms that the target shale sequences are present in Empire's EP187 tenement.

Open file Northern Territory Geological Survey data has been combined with these newly interpreted and mapped data sets and has confirmed an easterly extension of the Beetaloo Sub-Basin into EP187 containing the Velkerri and Kyalla Shales, Empire's primary and secondary exploration well appraisal targets, on trend and continuous with those in neighbouring Santos and Origin permits.

In the Beetaloo Sub-Basin, the Velkerri and Kyalla Shales are currently being drilled, appraised, and production flow tested to the west and north west of Empire's EP187 by Origin Energy and Santos. Empire has incorporated into its mapping and correlation work publicly available data from Santos' vertical Tanumbirini-1 well, approximately 76km to the north-west (Figure 1*) of Empire's proposed well (SL-4) location and Santos seismic data in EP161.

Tanumbirini-1 is currently being production tested by Santos after a 4-stage fracture stimulation and according to Santos "Gas flow rates of over 1.2 mmscf/d have been recorded, exceeding initial expectations for the vertical well. Preliminary gas composition analysis indicates >90% methane, less than 5% total inert content and 3% ethane."

Empire notes this result in the context of US shale development across multiple basins that has demonstrated that horizontal fracture stimulated wells typically produce at substantially higher flow rates than vertical fracture stimulated wells because they expose significantly greater volumes of hydrocarbon-rich rock surface area to the well bore.

Tanumbirini-1 well was drilled in one of the deepest parts of the Beetaloo Sub-Basin, reaching 3,945 metres in depth.

Empire's proposed exploration well location (SL-4) has equivalent thickness of Velkerri and Kyalla shales at depths approximately 1,000 metres shallower (Figure 1*) and is expected to reach total depth of approximately 2,500 metres.

SL-4 has a shallower target interval than Tanumbirini-1 to appraise resulting in lower drilling costs, and in a success case, lower field development costs. Being less deeply buried and therefore potentially less thermally mature, there is the potential that these target shales in EP187 may contain hydrocarbon liquids as well as natural gas.

2020 EP187 EXPLORATION DRILLING PLANNING

The new seismic has identified two areas that are relatively undisturbed by large faults (Figure 2*). One is the Phase 1 Work Program Area on the western boundary and the other is a southern area, though the latter may require additional future seismic acquisition to be further delineated.

New mapping demonstrates that the Phase 1 Work Program Area extends across approximately 160km2 (approximately 40,000 acres) (Figure 2*) on the western flank of EP187 that is a continuance of the play being tested by Santos at Tanumbirini-1.

The 2D seismic has been successful in determining the prospective areas for initial focus and the proposed Empire SL- 4 location for Empire's first exploration well as a de-risked location for exploration drilling.

Empire's proposed exploration well location has equivalent combined thicknesses of Middle Velkerri A, B, & C shales of approximately 500 gross metres (approximately 270 metres net), based on Tanumbirini-1 petrophysical cut-offs, and a Kyalla shale thickness of approximately 100 metres, all at depths approximately 1,000 metres shallower than encountered at Tanumbirini-1 (Figure 1*).

The Empire SL-4 well is expected to reach a total depth of approximately 2,500 metres. The net thickness of the Middle Velkerri shale interval of approximately 270 metres is significant compared to the most prolific North American shale plays. The analogous Marcellus Shale in the US Appalachia region has an average net thickness of 20 metres, the Barnett Shale in North Texas has an average net thickness of 100 metres and the Eagle Ford shale in South Texas has an average net thickness of 90 metres. These US basins currently produce millions of barrels of oil equivalent per day.

Concurrent with the seismic acquisition, Empire has sought regulatory approvals for four well pads as potential drilling locations with the Northern Territory authorities. This will facilitate the final well permitting process now that mapping results are available, giving Empire as Operator the flexibility to choose the best drilling location for our first exploration well, to be drilled in mid-2020.

Empire's initial exploration well will focus on evaluating the Velkerri and Kyalla formations to allow Empire to better understand hydrocarbon content and composition and rock mechanics. The well is being designed to allow for further appraisal work to be carried out in the future from the same well bore, thereby reducing future appraisal costs and operational footprint.

The well design will allow for a future vertical fracture stimulated flow test (subject to regulatory approvals) and ultimately the drilling and completion of a horizontal section (also subject to regulatory approvals) that would seek to achieve commercial flow rates.

SUMMARY

Alex Underwood, Managing Director, commenting on the results, said: "We are very pleased with the results of the EP187 seismic program. The seismic data have demonstrated that the most prospective petroleum productive shales of the Beetaloo Sub-Basin extend into our EP187 tenement at depths and thicknesses ideal for petroleum development.

The thickness of the Velkerri Shale in our initial priority target area exceeded our expectations, as has the depth and thickness of the Kyalla Shale, thereby opening an additional liquids rich play for Empire to explore and appraise. Our seismic program combined with historical open file seismic data demonstrates that the Velkerri Shale in our EP187 tenement is on trend and continuous with our neighbour Santos which has recently announced encouraging initial flow rates from the existing vertical well Tanumbirini-1.

Concurrent with our ongoing exploration activities throughout 2020, Santos' upcoming two well fracture stimulated horizontal appraisal drilling program targeting the Velkerri Shale and Origin's ongoing two well fracture stimulated horizontal appraisal drilling program targeting both the Velkerri Shale and the Kyalla Shale will enhance our understanding of the production potential of these shales in our properties given their broad lateral extent across the Beetaloo Sub-Basin.

With planning and approvals for our 2020 exploration drilling program targeting the Velkerri and Kyalla Shales well advanced and fully funded, and our priority drilling location de-risked, we are well placed to execute our 2020 exploration drilling program."
