Abstract: Having analysed a large number of production data of Jinglou oilfield and one of its pilot-Area O Pilot,this paper demonstrates the recovery characteristics and regularities of cyclesteam stimulation for a shallow and thin heavy oil reservoir. It is found that recovery rate andrecovery percentage are high,OSR is low,oil production decline factor is high and water cutrises rapidly.This paper shows that the technique and economics are succesful for shallowand thin heavy oil reservoir with thickness larger than 5 meters if production parameters areoptioned.
