Optimization is one of the most important parts in the field of engineering. Hydraulic fracturing is one example of optimization in petroleum engineering. In the past, stimulation was limited to low-permeability reservoirs. But now there are new techniques like high-permeability fracturing and technique tip screen out (TSO) which allows the stimulation of a variety of reservoir conditions. Therefore, the design will become more complex due to involve many variables that influence each other and more varied goal. The concept of Unified Fracture Design (UFD) can answer the challenge. UFD concept allowed two important notions. First, there is no difference between the low and high permeability in terms of benefiting for fracturing. Second, for any proppant mass injected into the well, there is only one geometry that would maximize production. <br /> <br /> In this paper we will discuss the comprehensive step in optimizing the economic design of the hydraulic fracturing. In this case, fracture length is the benchmark of design optimization, which affects the performance of the reservoir and determine the cost of treatment is needed. Both of these will counteract and form a net present value (NPV). The challenge is a sensitivity analysis that is how the other variables will affect NPV. This will be useful in deciding how the design will be made according to the economic objectives. Therefore created a computerized model of a software based methodology that has been made. This methodology applies in general to the various drainage area of reservoirs, but is still limited by the assumption of two-dimensional fracture. The software was developed using C # programming language with a simple framework that is easy to use even by common people. This software features a sensitivity analysis that allows an operator to define the main priorities cracking, how proppant type, size and quantity will affect the NPV at a specified time. Then the operator will select the best design to satisfy the objectives of economy for the long term and short term.
