ESTIMATION OF INITIAL STOCKS BASED ON THE MATERIAL BALANCE EQUATION

It was noted the need to assess the recoverable reserves of the main productive horizon of the Srednevilyui gas condensate field. Estimates of initial geological reserves of the productive horizon T1-III in retrospect are given. From the point of view of the operation of the gas-mode deposit, the initial reserves of the productive horizon have been assessed using the material balance method. The most adequate gas reserves calculated in 2000 y. are shown. It has been concluded that some deviation from the estimated 2000 y. gas reserves is due to the high gas content in the formation waters under the gas-water contact.
