Abstract
In case of extremely low permeability reservoirs, stimulation techniques are mostly required to enhance the production of wells. During these times of energy crises unconventional reservoirs have got significant importance. In such situations, proper designing and execution of hydraulic fracture job (HFJ) is required to produce wells at attractive production rates. By using this technique, wells can produce more, resulting in higher production from the reservoirs. In this paper, a hydraulic fracture job has been designed and its impact on oil production has been estimated by performing pre- and post-fracture reservoir performance calculations, using developed SMART software. While conducting this study, effect of varying fracture halflength in extremely low permeability oil reservoirs has been investigated and the impact of the same fracture half-length in varying permeability reservoirs has also been analyzed. The results of this study indicate that propagated fractures increases flow rate of wells. It has also been observed that initially the fracture halflength impacts the production appreciably; however, with further increase, it does not affect the production rate to the same magnitude
