Stimulation is a widely applied technique to enhance production of potential reservoirs which cannot deliver because of certain constraints, such as reduced permeability near wellbore or low permeability throughout the reservoir. Because of lower permeability and poor productivity a number of wells are shut-in because of their reduced ability to produce; especially while considering economical constraints. So, in such cases, stimulation has its significant role in increasing the well deliverability and productivity and hence bringing such wells to production as well as in general; increasing the production life of the wells. This paper gives a brief insight into usefulness of stimulation job, while specially emphasizing on hydraulic fracturing technique. In addition, an inhouse development of software is proposed, which can perform pre and post-frac analysis and also capable of incorporating outputs generated by any commercial reservoir simulator for in-depth and broader analysis and decision making.
