The Montemarciano permit is located in Ancona, Marche in central Italy, within the foredeep trough of the Central Apennines. The principal hydrocarbon plays are for biogenic gas in sand bodies in the shallow Pleistocene-Pliocene section and thermogenic gas in the deeper Miocene and older carbonates. One well has previously been drilled in the permit area, Monsano-1 (1972) which was P&A dry. Subsequent interpretation by Mediterranean O&G in 2009 determined that the well had been drilled off-structure leaving an untested inversion structure up-dip. This structure, Casa Tiberi, was characterised by an apparent seismic amplitude anomaly at its crest. In 2009 MOG withdrew from the permit and partner SARP took 100% interest.
Sound Oil farmed in to the permit in June 2011 by committing to drill the Casa Tiberi-1 exploration well to 700m. Casa Tiberi-1 was drilled in November 2011 to a TD of 715m in the Lower Pliocene Cellino sand objective. It encountered 14.9 m gross (3.9 m net) hydrocarbon pay. The well was completed with perforation of a single zone 571-581m. During clean-up flow, the well tested dry gas at rates of 26,400 – 25,900 scmd (about 0.92 MMscfd). The well was temporarily suspended pending a full test. The well was subsequently re-entered and a flow test delivered a final rate of 37,850 scmd (about 1.3 MMscfd) on 5/16 inch choke. The well was again temporarily suspended pending further evaluation of the test results.
SARP withdrew from the Casa Tiberi-1 operation after logging and opted not to participate in the completion and so going forward Sound Oil holds a 100% interest in the discovery. In May 2012 Sound Oil submitted an application for a concession to develop and produce the Casa Tiberi-1 discovery. The new concession will be designated San Lorenzo. The Montemarciano permit covers an area of 49.4 km2.
