Viura-1B Well Flow Rates Exceed Pre-Drill Expectations Doubling
Prospex's Net Production and Revenues
Prospex Energy plc (AIM:PXEN), the investment company focused on European gas and power projects, is very pleased to report the flow rates achieved from the flow testing of the recently drilled and completed Viura-1B development well in northern Spain, which have exceeded pre-drill expectations.
Highlights:
· Viura-1B has been completed and it is being tested, having achieved flow rates up to 500,000 scm/d (17.7 MMscfd), which is 72,000 scm/d (2.6 MMscfd) net to Prospex.
· The gas from the flow testing has already been sold on the market.
· The Viura-1B well will now be placed on long term production at a stabilised plateau rate of 300,000 scm/d (10.6 MMscfd), which is 43,000 scm/d (1.5 MMscfd) net to Prospex.
· Prospex's net production has more than doubled since the beginning of December to ≈82,000 scm/d or ≈2.9 MMscfd.
· This production increase does not include the production from the existing Viura-1ST3 well which has been producing intermittently since mid October at rates up to 200,000 scm/d (7.1 MMscfd), which is 29,000 scm/d (1.0 MMscfd) net to Prospex, as water handling issues are managed until the completion of the current workover on the Viura-3 water injection well.
· Recent increased energy prices in Europe have resulted in much higher revenues from the Company's investments.
· Enhanced production income will make an important contribution to continued expansion, with eleven further wells planned in the next 18 months to two years across Prospex's three onshore production concessions in Spain and Italy, and prospective blocks identified for acquisition in Poland.
Mark Routh, the CEO of Prospex, commented:
"The Viura-1B well test flow rates have exceeded pre-drill expectations from the larger than prognosed reservoir section of the main Viura reservoir target. The flow rates confirm the success of this development well with the added bonus that the gas produced from the flow tests has already been sold to the market and that the well is being put on long-term production at a rate of 300,000 scm/d which is 10.6 MMscfd (43,000 scm/d or 1.5 MMscfd net to Prospex). This and the production from the existing Viura-1ST3 well has more than doubled Prospex's net production - directly accruing revenues to the Company's investments as our gas and generated electricity are sold into the burgeoning European energy markets.
"More than doubling the production and therefore the revenue from our producing assets will put Prospex on an extremely sound footing to be able to fund its expansion plans of the eleven new wells currently going through permitting process on our approved onshore production concessions in Spain and Italy. It will also facilitate our proposed expansion plans onshore in Poland where we expect to be providing further news on the licence applications in the New Year."
Further Information
Prospex owns 7.2365% of the Viura field through its ownership of 7.5% of HEYCO Energy Iberia S.L. ("HEI"). Prospex is receiving 14.473% of the production income from the Viura gas field until payback of its capital investment (expected to be ≈£8 million) plus the accrued 10% p.a. interest thereon.
The Viura-1B well has been connected to the existing gas processing facilities at the Viura gas plant and the gas from the flow testing has been sold on the market since the flow testing commenced on 29 November 2024. Therefore, the Company has been accruing its share of that production income which will now continue as the well is placed on long-term production on completion of the flow testing programme.
Three zones have been completed and tested in the main reservoir target of the Utrillas-A formation in the Viura-1B well. The maximum flow rate achieved on test was 500,000 scm/d, which is 17.7 MMscfd (72,000 scm/d or 2.6 MMscfd net to Prospex). At the conclusion of the multi-rate flow testing and pressure build-up measurement programme the well will be placed on long term production at a stabilised plateau rate of 300,000 scm/d, which is 10.6 MMscfd (43,000 scm/d or 1.5 MMscfd net to Prospex).
At these rates, as from the beginning of December 2024, Prospex's total accrued net daily production from its Spanish and Italian portfolio has more than doubled from ≈38,000 scm/d or ≈1.3 MMscfd to ≈82,000 scm/d or ≈2.9 MMscfd. This enhanced production income from the three onshore revenue generating production assets is being accumulated to fund the drilling programmes on Prospex's three onshore production concessions on which there is a total of eleven further wells planned in the next 18 months to two years:
· The Viura Gas concession, northern Spain - two further development wells planned into the proven, developed producing Viura gas field in Q1/Q2 2025, one of which already has the full permit to drill approved. These two new production wells Viura-3B and Viura-3A will be placed on immediate production in the same way as the recently drilled Viura-1B well.
· The Selva Malvezzi concession, northern Italy - permit applications have been submitted to drill four further wells; two development wells into structures classified as contingent resources, North Selva and South Selva and two exploration wells classified as prospective resources, East Selva and Riccardina. These wells, which are targeting a total of 88 bcf gross (33 bcf net to Prospex), are anticipated to receive permits to drill in the second half of 2025.
· The El Romeral concessions, southern Spain - permit applications have been submitted to drill five further wells, two development wells into structures classified as contingent resources Sevilla-3E and Santa Clara-2 and three exploration wells Nuevo Gamo, Santa Rita and Romeral-2S classified as prospective resources. These five wells are targeting a total of 18.2 bcf gross (9.1 bcf net to Prospex). The Company hopes to receive permits to drill these five new wells by the end of 2025.
Prospex has also identified and hopes to acquire prospective blocks in Poland, which meet the Company's stringent investment criteria; namely, areas which have proven gas production, high potential prospectivity in the targeted geological horizons, high potential for new reserves to be unlocked and can be brought onstream within two to three years.

Notes
Prospex Energy PLC is an AIM quoted investment company focused on high impact onshore and shallow offshore European opportunities with short timelines to production. The Company's strategy is to acquire undervalued projects with multiple, tangible value trigger points that can be realised within 12 months of acquisition and then applying low-cost re-evaluation techniques to identify and de-risk prospects. The Company will rapidly scale up gas production in the short term to generate internal revenues that can then be deployed to develop the asset base and increase production further.
The Company currently has three non-operated, revenue generating, onshore producing gas investments in Europe with low operational risk:
• Selva Malvezzi, northern Italy (37% interest)
• El Romeral gas to power plant, southern Spain (49.9% interest)
• Viura Gas Field, northern Spain (7.24% interest)
Prospex also owns a 15% interest in the Tesorillo Exploration Permit in Southern Spain, with the option to increase to 49.9% and has identified and hopes to acquire prospective blocks in Poland, which meet the Company's stringent investment criteria.
The Company has no debt finance outstanding.
Net after-tax cash flows are as far as possible and where appropriate, retained within the Company's investment vehicles to fund expected future development costs therein and limit foreign exchange risk.
About Viura:
The Viura-1B development well, which has been drilled by HEYCO Energy Iberia S.L. ("HEI"), reached its revised targeted Total Depth ("TD") of 4,500 metres, which is ≈4,100 metres True Vertical Depth ("TVD"), on 21 October 2024 in the 6-inch hole section of the bottom 450 metres of the well. Prior to drilling the current Viura-1B well, the Viura producing gas field onshore in northern Spain had an estimated gross original gas in place of 211 Bcf (6 Bcm) and estimated reserves of 105 Bcf (3 Bcm). To date, just 16 Bcf (0.5 Bcm) of gas has been produced from Viura meaning that the remaining reserves were estimated as 90 Bcf (2.5 Bcm), which is 6.5 Bcf (0.18 Bcm) net to Prospex.
The Viura-1B well was deepened by 450 metres in order to appraise the undrilled Utrillas-B formation and assess if it was gas bearing. Having confirmed the presence of gas-bearing reservoir quality sandstones in the Utrillas-B, the operator completed this interval with a cemented 4½ inch liner. The flow testing programme for the Utrillas B section will be performed during the planned plant shut-down in H2 2025.
The drilling rig has been moved from the Viura-1B well site location to the produced water disposal well Viura-3 site and operations are underway to re-instate its operability to better manage produced water from the existing Viura-1 ST3 production well.
Following the shut-in of the Marismas gas concession for its conversion to a gas storage facility, there are now only two producing onshore gas fields in Spain: El Romeral and Viura. Prospex is a co-owner in both of these concessions. Prospex owns a 49.9% share of the El Romeral concessions and a 7.2365% of the Viura concession.
HEI currently has a 58.7964% interest in Viura. The other participants in the ownership of the Viura Field Development are Sociedad de Hidrocarburos de Euskadi, S.A. ("SHESA") (owner of the 37.6901% of the Concession) and Oil and Gas Skills, S.A. (owner of the 3.5135% of the Concession). On 5 April 2024, HEI entered into an asset purchase agreement with SHESA for the acquisition of the participation of SHESA in the Viura Field Development, which is subject to the fulfilment of certain conditions precedent. Prospex through its 7.5% shareholding in HEI indirectly owns 7.2365% of the Viura concession, its reserves and the existing surface production facilities of the Viura gas plant, which is connected to the Spanish national grid.
HEI acquired its interest in the Viura gas field and became operator in 2022. A new 3D seismic survey was acquired in 2013. There is one well in production in the field Viura-1 ST3, which had been shut in until recently. This well produces intermittently as water production is managed. There is a workover now underway on the existing produced water disposal well Viura-3 to reinstate its operability. HEI has permits in place to drill one further development well, Viura-3B, scheduled to start in the second quarter of 2025. Permits have been submitted to drill a third development well on the concession Viura-3A batch drilled with Viura-3B well in Q2 2025.
The Viura-1B well commenced drilling operations on 22 June 2024. The new investors (including Prospex) into HEI are funding 31.58% of the development costs to earn 15.79% ownership of HEI. Prospex is funding 15% of the development costs of the HEI development programme comprising the current well in 2024 and the proposed 2025 two well drilling programme to earn 7.5% ownership of HEI and indirectly 7.2365% of the Viura asset.
Other new investors are funding 16.58% of the development costs to earn an 8.29% ownership in HEI.
The two new wells to be drilled from the first half of 2025 and completed in the second half of 2025 are to be funded from revenues from existing and new production from Viura or from new funds if required. Since 29 November 2024, Viura-1B has been generating revenues from production from the start of the testing programme. The 2025 development programme is to be funded by future cash calls or from Phase 1 production or both.
There is a preferred pay-back mechanism for Prospex and all participants (including HEGI and new investors) of this new investment in HEI, the ("HEI Investors"). The HEI Investors will enjoy a 10% interest on their capital investments paid out from the existing and future production from Viura. Until the HEI Investors have recovered their full capital commitments, plus the 10% preferred interest return, HEGI will not receive production income on their other 50% ownership of HEI over and above operating expenses and an allowance for Spanish taxes and royalties. This means that Prospex will earn 14.473% of the revenues from the gas production from the Viura field until it has achieved payback of its total expected ≈£8 million capital investment. The gross cost (including the current Viura-1B well which has already been funded) of the three phase, three-year Viura development programme is estimated at a total of £55.4 million ($70.4 million). HEGI is funding over 50% of that programme and the new HEI Investors are funding 31.58% through their interest in HEI which earns them an indirect 15.2368% ownership of the Viura asset (net 7.2365% to Prospex).
