Highlights:

• Workover Rig Mobilisation will commence on Friday 19 June 2020.
• Testing Operations are expected to commence approx. 7 days after mobilisation.
• Testing Programme includes the installation of permanent production tubing and flow control equipmentin the well, underbalanced perforation and production testing of the well.
• Test Objectives are to determine the production capacity of the well and confirm the suitability of the gas composition for commercial sales.
• After Testing the well will be shut in awaiting commercial production.
• Gas CommercialisationStudies are ongoing to determine the viability of two development optionsincluding the delivery of sales gas to the grid at the nearby Satchinez-Calacea Gas Plant (a 12 km tie-in) or alternately the conversion of produced gas to power and the connection to a high voltage power line located approx. 2km from the Iecea Mica-1 (IMIC-1) location.
• Resource Upside to be further accessed using high resolution 2D seismic across IMIC-1 and potential IMIC-2 accumulations to better define the extent of gas zones where ADX has identified substantial stratigraphic upsidebased on existing2D seismic data and well data.The high resolution 2D seismic will be acquired during 3rd quarter of 2020 together with a 3D seismic survey in the surrounding Parta exploration license.

IMIC–1 Drilling Results

• IMIC-1 well encountered gas across three zones with a combined total arithmetic sum for the three zones of 20 BCF 2C contingent resources estimated (refer to table below). The well was suspended for future completion as a producer following testing. Testing has been deferred until down hole well production equipment was manufactured and then further delayed due to border closures caused by the Covid-19 pandemic which have prevented testing operations until now.

ADX Energy reports that workover rig mobilisation will commence on the 19th of June 2020 in preparation for production testing the successful IMIC-1 well that was drilled in late 2019. Testing of the IMIC-1 well was deferred until down hole production equipment was manufactured so that the well could be optimally completed utilising underbalanced perforation with a view to maximising well productivity. Further delays have been encountered due to Covid-19 pandemic related border closures which have resulted in the inability to import required testing services from neighbouring Hungary and Germany as well as mobilising key personnel to the site.

Production testing will commence following setup of the work over rig, removal of the well head,installation of permanent production tubing and flow control equipment as well as the perforation of the well casing utilising underbalanced inflow techniques to maximise well production.

The testing program has been designed to determine the production capacity of the well through multiple flow rate measurements and pressure build up response measurements. Produced gas will be sampled to determine the suitability of the IMIC-1gas composition for commercial sales. The expectation based on mudlog data and nearby analoguesis that a dry gas will be produced which will require minimal processing prior to market delivery.

Testing will concentrate on the PA IV sand (Pliocene age) which is a proven reservoir and has the greatest upside reserves potential of the 3 hydrocarbon bearing reservoir intervals intersected in the IMIC-1 well (refer to table below). This reservoir unit has a large stratigraphic upside potential which will be further quantified in the near future with the planned high resolution 2D seismic program scheduled for the third quarter of 2020.

Following the completion of the production testing program the well will be shut in awaiting commercial production at a future time.

Gas Commercialisation Studies

Engineering studies are ongoing to determine the potential viability of two development options including the delivery of sales gas to the grid at the nearby Satchinez-Calacea Gas Plant or alternately the conversion of produced gas to power and the connection to a high voltage power line located approx. 2km from the IMIC-1 location.The production test results will provide important information required for the finalisation of feasibility studies.

Gas Resource Assessment

The resource potential of the three gas reservoirs intersected at IMIC -1 will be further assessed utilising high resolution 2D seismic that will be acquired across IMIC-1 and potential IMIC-2 accumulations. The appraisal seismic is expected to better define the extent of gas zones where ADX has interpreted substantial stratigraphic resource upside. The appraisal seismic will be acquired in conjunction with the planned 3D seismic program during the 3rd quarter of 2020 in close proximity to the IMIC -1 and the IMIC-2 wells.

Asset Ownership Structure

ADX holds a 49% shareholding in Danube Petroleum. The remaining shareholding in Danube is held by Reabold Resources. Danube via its Romanian subsidiary, ADX Energy Panonia, holds:

• a 100% interest in the Parta Exploration license in Romania (including a 100% interest in the Parta Sole Risk Area). Upon completion of a farmin by Tamaska Oil & Gas subsidiary Parta Energy, Danube will hold a 50% interest in the Parta Exploration License;and
• a 100% interest in the Iecea Mare Production license in Romania (which hosts the IMIC-1 well and future IMIC-2 well).
