Notes to editors

Block Energy plc is an AIM-listed independent oil and gas company focused on production and development in Georgia, applying innovative technology to realise the full potential of previously discovered fields.

Block has a 100% working interest in Georgian onshore licence blocks IX and XI^B. Licence block XI^B has 2P reserves of 64 MMboe, comprising 2P oil reserves of 36 MMbbls and 2P gas reserves of 28 MMboe (Source: CPR Bayphase Limited: 1 July 2015). Additionally, following an internal technical study designed to evaluate and quantify the undrained oil potential of the Middle Eocene within the Patardzeuli field, the Company has estimated gross unrisked 2C contingent resources of 200 MMbbls of oil. Licence block XI^B is Georgia's most productive block, with historical production of over 180 MMbbls of oil from the Middle Eocene, peaking in the mid-1980s at 67,000 bopd.

The Company has a 100% working interest in licence block XI^F, which contains the West Rustavi onshore oil and gas field. Multiple wells have tested oil and gas from a range of geological horizons. The field has produced over 75 Mbbls of light sweet crude and has 0.9 MMbbls of gross 2P oil reserves in the Middle Eocene. It also has 38 MMbbls of gross unrisked 2C contingent resources of oil and 608 Bcf of gross unrisked 2C contingent resources of gas in the Middle, Upper and Lower Eocene formations (Source: CPR Gustavson Associates: 1 January 2018).

Block also holds 100% and 90% working interests respectively in the onshore oil-producing Norio and Satskhenisi fields.

The Company offers a clear entry point for investors to gain exposure to Georgia's growing economy and the strong regional demand for oil and gas.
