Abstract: In view of high level of petroleum Resources exploration in Jiyang depression, how much the resource potential has after all? How many reserves will be discovered in the future? It is the focus that the petroleum geologists pay more and more attention to. Based on changing trend of proved reserves and exploration benefit over the years in Jiyang depression, the life model simulation method (including Logistic, Hubbert, Compertz and HCZ models) and the exploration benefit method (including discovery rate per well and discovery rate per footage models) are applied to prediction of additional proved reserves accumulated in each period of 2006—2010, 2011—2015, 2016—2020 and 2021—2030, which provide scientific basis for drawing up the development plans in medium and long-term oil-gas exploration in this area.

Key words: Jiyang depression, petroleum resource, model, simulation, prediction, forecast
