Abstract: Based on the incremental proven oil-gas reserves every year and the relevant discovery history, along with the targets of "the Eleventh Five-Year Plan" and exploration deployment, the conventional oil-gas reserves increasing trend in 25 years to come is predicted using Logistic, Comperts and Hubbert methods. In the present conditions that Sinopec-controlled exploration areas do not change and exploration investment requirement remains the same on the whole, it is predicted that the newly incremental proven oil accumulative reserves will reach 11.28×10⁸ t, newly incremental proven gas accumulative reserves will be 7 100×108 m³ during the period of 2006- 2010; 10.75×10⁸ t to oil, 7 359×108 m³ to gas of 2011-2015; 10.70×10⁸ t to oil, 7 792×108 m³ to gas of 2016-2020; 9.08×10⁸ t to oil, 6 422× 108 m³ to gas of 2021-2025, and 6.81×10⁸ t to oil, 4 495×108 m³ to gas of 2026-2030, all of which shows good potentials for oil-gas exploration in the future in Sinopec-controlled exploration areas.
