SEC reserves are important assets for oil and gas companies,and the assessment of asset value is also important for new production blocks.Block A is an important tight gas-producing area in China.In the initial production stage,there are few producing wells,making it difficult to assess the technically recoverable reserves.Based on the premise that the geological characteristics and reservoir characteristics of Block A and its adjacent Block B are similar and comparable,this paper adopts the dynamic analogy method to evaluate the SEC reserves of Block A in the initial stage of production.The technical recovera-ble reserves of the production wells in Block A are 850 × 104m3 per well,with a total technical recovera-ble reserves of 700 × 104 m3 per well,which is consistent with the actual production situation.This meth-od will guide the evaluation of SEC reserves of CNOOCs new production tight gas blocks in the future,and provide insights for the industry.
