The Ukrainian authorities have recently done a lot to change the regulatory and investment environment in the field of gas extraction: a special stabilisation clause has been drawn up for the period from 1 January 2018 to 1 January 2023 to set attractive rents, the tax system has been improved and the authorisation system simplified. Under a production-sharing agreement, one party, Ukraine (the State), the other party, appoints the investor, with the research, exploration and exploitation of mineral resources in certain underground surfaces and the execution of the work related to the contract for a specified period, while the investor undertakes to carry out the transferred work at its own expense and risk. with an additional indemnity and receipt of payment (remuneration) in the form of part of the production profit. Such a definition of production sharing agreements is provided for in the Law of Ukraine on Production Sharing Agreements (PSA Law). In recent years, Ukraine has made considerable progress in implementing its ambitious economic reform agenda. After a sharp contraction of the Ukrainian economy in 2014-2015, the first signs of improvement were visible in 2016 and 2017. Energy independence is a priority for the government and can be achieved through domestic gas production to reduce its dependence on natural gas imports. To speed up the process, officials came up with the idea of designing a Psa model. According to USAID, the main advantages of the PSA model (i) are the availability of the basis for negotiation between Ukraine and investors; (ii) greater transparency; and (iii) protect the interests of Ukraine with the arrangements agreed in advance. .
