The company reported on 29 May 2020 that the well, which is located approximately 2.5 km to the southwest of the abandoned Portita gas field, was a dry hole. Portita 10 had a planned TD of 1,536 m and was understood to be targeting gas within the Miocene series. Civil works began in January 2020 and it is believed that the well was drilled in March.  The E X-1 Voivozi block, located in western Romania close to the Hungarian border, was awarded to MOL and Expert Petroleum in April 2011. The block was offered as part of Romania 10th licensing round.
