Prospex Oil and Gas Plc: Preliminary approval of production concession application, onshore Italy

Published by
Oilfield Technology,

Further to the announcement of 29 May 2018, Prospex Oil and Gas Plc, the AIM quoted investment company, is pleased to announce that it has been advised by the operator, Po Valley Operations Limited ('PVO'), that the production concession application to develop the Selva Malvezzi Gas-Field (‘Selva’) in northern Italy (the ‘Production Concession’) has received preliminary approval from the Italian Government.

Prospex holds a 17% interest in Selva, which sits within the 331 km² Podere Gallina Exploration Permi in the Po Valley region of Italy.

The Development

The proposed development centres on the installation of a fully automated gas plant at the existing Selva/Podere Maiar-1d appraisal/redevelopment well site. Based on dynamic reservoir studies, phase one is targeting daily production at a rate of up to 150 000 m3 (5.3 million sft3/d) from two gas-bearing reservoirs, C1 and C2, in the Medium-Upper Pliocene sands of the Porto Garibaldi formation. In addition, a 1 km long pipeline will be laid to connect the plant to the Italian National Grid.

Podere Maiar was drilled in Q4 2017 into Selva (previously operated by ENI), which historically produced 83 billion ft3 of gas between 1960 and 1984. During testing, peak flow rates of 148 136 scm/day (5.2 million sft3/d) on a 3/8 in. choke and 129 658 sm3/day (4.6 million sft3/d) on a 3/8 in. choke were recorded from the C1 and C2 reservoirs respectively.

A further phase of the development is planned, which is contingent on the results of a planned 3D seismic acquisition programme (subject to JV approval) and involves PVO drilling additional wells to significantly expand the Production Concession’s natural gas resource base. Drilling will target prospects including Selva East and Selva South Flank which fall within the Production Concession area. 3D seismic will be acquired across these areas in 2019.

Final approval from the Italian Government is subject to customary regulatory processes being completed, including the approval of an Environmental Impact Assessment.

Prospex non-executive Chairman, Bill Smith, said, “With the preliminary approval of this Production Concession, Podere Gallina remains on course to become Prospex’s second revenue generative asset when it comes on stream in 2020, alongside our 50% interest in the producing Suceava licence in Romania. As with Suceava, Podere Gallina offers significant development upside and, importantly, the approved development plan covers multiple prospects that have already been identified on the licence. These prospects will be targeted through the acquisition of 3D seismic data to further de-risk the additional prospectivity and inform a future well programme.

“The approval marks an excellent start to 2019 for Prospex. With activity planned across our portfolio, including work to advance the up to 2 trillion ft3 Tesorillo Gas Project in southern Spain, together with our continued efforts to acquire interests in additional onshore European projects that match our strict investment criteria, 2019 promises to be an exciting year for Prospex. I look forward to providing further updates on our progress, as we focus on exposing our shareholders to a continuous pipeline of opportunities that offer significant re-rating potential.”
