The optimization of gas condensate fields

Applied hydromechanics, Vol. 17 (89) ¹ 1, (2015) p.37-52
An optimized distribution pattern has been developed for gas well production to maximize the extraction of condensed C5+ hydrocarbons from natural-gas condensate fields. The pattern uses a mathematical regular filtration model for two-phase multi-component hydrocarbon liquids with reference to phase transitions. The pattern enables efficient management of condensate gas fields and considers debit limits of individual wells, including temporary inactive modes for condensate wells during maintenance periods. The efficiency of the new approach is evidenced by data from Kotelevskoye condensate gas field (Ukraine). It has been demonstrated that, in the best case scenario, over 12% increase in gas production can be achieved by reducing in-situ flows and thus preventing (a) additional condensate formation (in the depletion mode), or (b) premature dry gas breakthroughs in gas producing wells (in the cycling process mode).
