document: On 30 November 2019, INA Industrija Nafte d.d. (INA) completed drilling new-field wildcat Jankovac 1 in the Drava 2 permit in northeastern Croatia. The well was drilled to the final depth of 1,635 m (TVD 1,598 m) in an undisclosed Mesozoic succession. The results of the well, solely operated by INA, have yet to be disclosed.  Jankovac 1 was spudded on 14 November 2019, using the National 402 drilling unit from Crosco. The well is located in the northern sector of the permit, approximately 10 km west of the city of Koprivnica. In a geological sense, the well is situated within the Somogy-Drava Sub-basin, tectonic unit of the Pannonian Basin.  The well had an initial planned final depth of 1,400 m, targeting the Lower and Middle Miocene successions. A secondary target was in the Mesozoic basement series.  Background Information  The 2,468 sq km Drava 2 block was granted to INA on 10 June 2016, from the country's 1st onshore bidding round (closed on 18 February 2015).   The permit encompasses some 30 fields and discoveries (carved out from the permit area), in particular the Molve and the Kalinovac gas fields.  The latest drilling operation in the country dates back to mid-2018, when INA abandoned dry wildcat Mala Jacenovaca 1. The well was drilled to the total depth of 1,223 m (TVD 1,171 m) in the Middle Miocene series.
summary: Jankovac 1 nfw. (INA 100%) in the Drava 2 permit in NE of the country, completed. The well was drilled to the final depth of TD=1635m in an undisclosed Mesozoic succession. The results of the well, have yet to be disclosed.
