| 总结: | The increasing global energetic demand forces the researchers to search for new extraction approaches of oil resources, inducing the industry to invest in the production of unconventional reservoirs, which access is more difficult and requires the use of high development technologies. An example of this kind are the tight gas reservoir that present a permeability bellow 0.1 MD. In the past, these reservoirs were considered uneconomical, once that they were expensive and had a low production. The study and investment in techniques, such as hydraulic fracturing, made it possible to produce large volumes of gas, making up the production cost. The purpose of fracturing is to increase the productivity and injectivity index, creating a path of high conductivity between well and reservoir through the pumping of proppant. However, analyses to enhance the production become indispensable, since this technique involves considerable costs. Thus, the objective of this work was to perform an analysis of how the proppant properties will impact in production. The studies were conducted using the IMEX module from CMG (Computer Modelling Group) version 2013.1, assisted with a complementary program developed in Microsoft Office Excel 2007. During this work the mass of proppant were varied in six concentrations and entitled as proppant "A","B", "C", "D", "E" and "F", evaluating its properties and influences in the production of a tight gas reservoir drilled vertically. It was discovered that the increase of some properties didn't result in significant benefits to production, reinforcing the necessity to make careful analysis in the design of fracturing projects. The pumping of 90000 lb. of proppant "A" presented the best result in this study. |
