PROJECT

Cudi-Gabar Oil Petroleum Province, Türkiye

Five years ago, this part of Türkiye produced almost no oil. Today, the Gabar fields around the M47 Block are producing over 83,000 bbl/d from discoveries that didn’t exist a decade ago. Dune Oil is earning a 29% working interest in the block by funding US$15 million across two work program tranches covering seismic acquisition and drilling.

The block lies about 11 km from the Şehit Aybüke Yalçın field, Türkiye’s largest onshore oil discovery, and is surrounded by multiple new TPAO discoveries across the Cudi-Gabar province.

The oil blocks are surrounded by >10 major oil discoveries, half of which are recent.

2C NPV10, risked (81% chance of development)

One discovery. Three more targets on trend.

On the same south-dipping carbonate fairway, Bulmuşlar, Şehit Aybüke Yalçın and Esma Çevik are among the TPAO fields producing more than 83,000 bbl/d. Dune Oil’s M47 discovery sits on this trend, and three mapped structures follow.
