| Summary: | As the increasing demand of gas for energy, the unconventional reservoirs e.g. tight gas reservoir is being targeted as another source of energy. One of the challenges encountered in producing gas from this reservoir is the small value of the permeability. Thus, hydraulic fracturing treatment is needed to produce an adequate volume of gas with a desirable rate in economic perspective. In order to optimize the hydraulic fracturing treatment, several parameters are needed to be considered. These parameters can be categorized into three groups: proppant properties, reservoir properties, and fracture properties. The study will provide the determination of optimum geometry of fracture for different configuration of fracture spacing for the same drainage area by making the partition from the fracture. Will be continued by combining the production forecasting with unified fracture design. The study is also complemented with the effect of fracture spacing configuration in different value of permeability. With production forecast, it can be concluded which fracture spacing will achieve the highest recovery factor and ultimately the NPV value among other configurations of fracture spacing. All of the properties above will determine the geometry of the fracture. Increasing in number of fractures is not always resulting in maximum recovery factor and maximum NPV. The solution given in this paper can be taken into account for future optimization of hydraulic fracturing. The novelty of combining the method of unified fracture design and production forecasting is in its practical use for the industry on its pre-feasibility study to forecast the production. |
