Prospex Energy (PXEN PXEN) has reported the successful completion of a 3D geophysical acquisition campaign over the Selva Malvezzi production concession in Italy, with the work finished on budget and ahead of schedule. The survey will help to refine the joint venture’s planned four-well development programme and support future resource upgrades.
Po Valley Operations, a wholly owned subsidiary of Po Valley Energy, operates the Selva Malvezzi production concession with a 63% working interest, while Prospex holds the remaining 37%. The survey area covered about 140 square kilometres across the concession.
Data acquisition began on 13 November 2025 and was completed on 27 November 2025. The campaign recorded 5,052 vibration points, with only three hours of weather downtime. The contractor deployed 8,380 wireless geophones and used single sweeps from four Vibroseis trucks operating simultaneously in separate quadrants.
The acquired data is now being collated and will undergo time-domain volume processing over the coming months, aiming to deliver a high-resolution three-dimensional subsurface model to support future field development planning and potential resource upgrades. The operator plans to complete the interpretation of the processed data in-house, with results expected to be announced in Q2 2026.
Prospex's CEO Mark Routh said: "I am very pleased to report that Po Valley Energy has completed this ambitious work programme safely and efficiently. With the benefit of an unusually dry November the survey has been completed on budget and ahead of schedule.
"The Po Valley team in Italy are to be congratulated for delivering an excellent project whilst co-ordinating the two contractors Geofizyka Toruń, on the data acquisition and Geotec in support of the complex permitting process throughout every phase of the project.
"The processed results will be interpreted in-house by the Po Valley team with the dual objective of optimising the subsurface drilling targets of the four new wells to be drilled on the Selva Malvezzi concession and delivering an upgrade to the certified gas resources."

The completion of this large-scale 3D seismic survey on time and on budget is a positive operational milestone for Prospex as a 37% partner in Selva Malvezzi. The high-density dataset should help to optimise drilling locations for the planned four-well programme and could underpin future certified resource upgrades, strengthening the asset’s strategic value in Prospex's European gas portfolio.
