Hydraulic fracturing is one of the stimulation methods to increase rock permeability. Hydraulic fracturing is commonly used in reservoir that have low permeability and wells which have a decline in production rate. In many cases, hydraulic fracturing show significant success which is marked by an increase in the production rates. In this paper, hydraulic fracturing will be conducted by observing the effects of pumping rates. A case example is taken from an oil well that has a low resistivity reservoir, which is HAP#532 well. This low resistivity causes the reservoir to have low permeability and small production rates. The scenario of hydraulic fracturing in HAP#532 well is done by using several different pumping rate sensitivity, start from 10 BPM, 20 BPM, and 30 BPM, as based on 15 BPM base case pumping rates to obtain the most optimal pumping rate. Therefore, it can be seen how much the effect of pumping rates on hydraulic fracturing. From three scenarios performed by using FracCADE and Prosper, author get the optimal pumping rate is 20 BPM. At this pumping rate, the fracture geometry obtained fracture half-length (Xf) is 213 ft, fracture height (hf) is 45.6 ft, fracture width (Wavg) is 0.56 inch, average permeability is 58.09 mD, and the production rate is 348 BOPD.
