Predicting development parameters for gas-condensate deposits with oil banks in the exploitation of horizontal wells

M.S. Khalilov

The paper presents comparative analysis of technological parameters of depletion and water-oil displacement modes during the exploitation of oil banks in gas-condensate deposit with horizontal well in gas-free production rates based on the three-phase multi-component filtration model. In water-oil displacement regime the oil recovery factors were higher compared to the depletion mode. The development profitability was justified. The increase of oil recovery factor in water-oil displacement regime is achieved due to the weak rate of flooding in well production and unrecoverable capacity of the fluid injected into the reservoir. The practicability of oil banks exploitation in gas-condensate deposit in gas-free rates at the first stage of development in depletion and in water-oil displacement modes at further stage correspondingly is justified.
