Development of a Simulator for Determination of Optimal Fracture Geometry in Arenitic Reservoirs
Hydraulic fracturing, proppant, unconventional reservoirs
The search for new oil resources is due to the growing world demand for energy, leading the sector to invest in the production of unconventional reservoirs. They have more difficult access and greater technological investment for their development. As an example, there are the Tight Gas and Tight Oil reservoirs, which have low permeability. In the past, these reservoirs were considered uneconomical, not only for their low production, but also for the high cost involved in their development. 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 is to develop a program in Visual Basic for Applications, to analyze the characteristics of the proppant and the fracture geometry in productive terms in hydraulic fracturing. Changes were made in the mass quantity of proposed objects found on the market and, consequently, in their properties. For the case under study, the Sinter Lite 16/30 was the most attractive in terms of productivity.
