Abstract: Reserve-production ratio (RRP) is defined as the ratio of remaining recoverable reserves to annual production rate in a year for a country, an area or an oil-gas field. RRP can be analyzed and applied for diagnosis of a field’s development stage, stable production situation and resource guarantee degree. If value of RRP is too high, it will overstock capital in the form of reserves available; if the value is too low, it will result in low production guarantee degree. This paper studies the changing rules of RRP in different development stages of oilfields, the cut-off value in stable production stage, and incremental recoverable reserves required under planed output in terms of requirements of RRP in different development stages. Finally, the status and changing trend of RRP in areas or fields subordinated by Sinopec are estimated.

Key words: reserve-production ratio (RRP), exploration, development, analysis
