Tatneft, which possesses one of the oldest fields in the country, Romashkinskoye, has asked for tax concessions for further extraction of oil residues from it. "We have extracted everything, it is impossible to do it at a cheaper price," Director General of the company Nail Maganov claimed at a press conference explaining the necessity of zero mineral tax for up to three years in exchange for a trillion rubles of investments in the network of wells. On the one hand, prospects of the lobbied initiative in the light of head of tax service Mikhail Mishustin's appointment as chairman of the government are looking improbable. However, the premier has already dealt with concessions for special economic zones.
