On 2 March 2020 Shearwater GeoServices confirmed the award by Total of a 3D seismic survey acquisition and Fast Track processing project using Shearwater's Reveal software in the 1-21 Han Asparuh licence. The acquisition commenced on approximately 10 March 2020 and it is expected to continue until mid-June 2020. On 8 April 2020 the 3D seismic acquisition was ongoing. The 3D seismic survey is being carried out by the "Oceanic Vega" vessel and it will cover an area of 5,500 sq km. Given the size of the survey, it will cover most of the licence east of the 2013 3D seismic survey. The drilling location of an exploration well will be defined after the seismic interpretation is complete. The well will be the fifth well on the licence and it is likely to be drilled in early 2021. The 1-21 Han Asparuh licence is set to expire in May 2020 but Total intend to extend the licence validity for an additional two years.   Since 2016 Total drilled three exploration wells in the licence using the Noble Globetrotter II drillship: Polshkov 1, Rubin 1 and Melnik 1. Polshkov 1 was spudded in May 2016 targeting Lower Oligocene sandstones, Middle Eocene sandstones and Upper Jurassic to Lower Cretaceous carbonates. The well reached a total of 5,615 m and was plugged and abandoned as a discovery. Partner Repsol reported that the well encountered oil and gas in an Oligocene play. In January 2018 the company completed the drilling operations in the Rubin 1 exploration well. It was drilled in a water depth of about 1,500 m about 14 km northeast of the Polshkov 1 exploration well. It had a planned total depth of 5,500 m with several targets, but its main objective was the Polshkov High structure. The well encountered significant gas shows in the Middle Miocene. In December 2018 Total suspended its operations in the Melnik 1 exploration well. The wellâs result was not communicated. It was spudded in a water depth of approximately 1,950 m. Melnik 1 had objectives in Eocene sandstones and Oligocene fans at a depth of approximately 5,500 m below sea level.  Interest in the 14,220 sq km 1-21 Han Asparuh permit is held by Total E & P Bulgaria BV (40% + operator), OMV offshore Bulgaria GmbH (30%, operator until May 2014) and Repsol SA (30%).
