Reduction of Hydrate Formation During Operation of Wells at Tagulskoye Field

Abstract

The analysis of the situation of hydrate formation on the technological equipment installed on the wells of the Tagulskoye field was carried out. The necessity of using Warm Stream technology is substantiated. An economic and technical analysis of the proposed design solutions was carried out. It has been established that the replacement of the existing integrated method for combating hydrate formation with the Warm Stream and bypass valve installation will make it possible to obtain an annual cost savings of 7,011 thousand rubles at the wells of the Tagulskoye field. In addition, there will be a decrease in the number of energy consumers, a decrease in the number of current-carrying wires, and the injection of a hydrate formation inhibitor will be excluded. As a result of the implementation of the project activities, there will be a reduction in the labor costs of workers for replacing the heating cable and working with special equipment, as well as an increase in additional oil production as a result of a decrease in daily downtime of wells.
