Abstract

Abstract:

Several Chinese oil companies are listed on the U.S. stock market,their petroleum reserve disclosure by SEC proposed rules is indispensable,and the proved reserves is the most concerned.We face great challenges for SEC reserves disclosure because of crude price changing,operation costs rising and other factors,it is necessary to determine the impacts of oil price and operation costs on proved reserves reporting.Taking the A oilfield in China as an example,we obtained various combinations of oil price and operation costs by increasing price and cost at a rate of 10%.Based on calculation with ORGE software,we analyzed the impacts of changes of oil price and the cost on proved reserves reporting.The results show that proved reserves might increase as oil prices rise,but the increasing rate tends to decline gradually.The proved reserves might reduce as operating costs increase,but the decreasing rate also tends to decline progressively.The impacts of oil price and cost on proved reserves is nonlinear,and can be divided into three stages,including dramatic impact,moderate impact and weak impact stages.

Key words: oil price, operation cost, sensitivity analysis, proved reserve, reserve evaluation
