ANALYTICAL EXPRESS CALCULATION OF THE MAIN INDICATORS OF THE DEVELOPMENT OF A NEW OIL AND GAS RESERVOIR FOR MULTIVARIATE CALCULATIONS IN ORDER TO OPTIMIZE DESIGN SOLUTIONS

Abstract

The assets of Rosneft Oil Company PJSC include oil and gas reservoir that have not been put into development, in addition, the resource base is being replenished through geological exploration. The use of new technologies in exploration and production, the introduction of new software modules for calculations, tax regimes for oil production create prospects for increasing production from oil and gas reservoir that have not been put into development in the whole of the Russian Federation. At the stage of decision-making on putting new assets into development, it is required to be able to conduct an express assessment of technological indicators.
 This paper presents the results of the formation of analytical approaches for carrying out express calculations of the development indicators of oil and gas, gas-oil and oil-gas condensate reservoir that have not been put into development.
 The calculations are based on the use of a set of pre-calculated displacement characteristics and the material balance equation of hydrocarbon reservoir. All developed algorithms are implemented in a new software module, which is an integral part of the RN-KIN corporate information system, the main tool for a development engineer at Rosneft Oil Company PJSC.
 This paper reflects the mathematical description of the algorithm for the express calculation of development indicators, the main tasks that were solved in the course of the work, and the results obtained.
