"Unconventional" resources are defined as hydrocarbons found in reservoir rocks that are not very permeable, which makes it difficult for the fluid to move through them. A highlight in unconventional production is shale gas, due to the low permeability of this type of formation. In this context, this work aims to compare gas production velocity profiles from shale formations and analyze the flow using software: ANSYS and MATLAB. In addition, the influences of this flow on the New Albany and Antrim wells will be analyzed. The results show that the Antrim well performs better. This may be associated with the hydrogen injection process.
