Abstract
In the presented work, the possibility of preventing the formation of gas hydrates at the Novo-Chaselskoye field by means of metered methanol injection is considered. The current state of field development and information on reserves are presented. A method for calculating the amount of an inhibitor (methanol) required to prevent hydrate formation for Cenomanian gas is presented. As a result of the study, the amount of methanol consumption for hydrate-free well operation was calculated, the conditions and places of possible hydrate occurrence were analyzed, and the required amount of hydrate formation inhibitor was calculated to be supplied to the wellhead to prevent hydrate precipitation.
