4. Conclusions Hydraulic fracturing consists of several key steps, including perforation, fluid injection, and post-injection cleaning, which together create a pathway within the geological formation. Fluids play a crucial role in this process by transporting proppants and enhancing production efficiency. It is essential for the fluid to have an appropriate viscosity to prevent sand from settling at the bottom of the fracture. Hydraulic fracturing models offer valuable insights into the occurrence and propagation of fractures, allowing operators to optimize treatments and minimize risks. Various models, such as the KGD and PKN, have been used to simulate hydraulic fracturing, providing a smooth representation of fracture propagation. However, these models often do not account for the gradual changes in fracture length and width over time. The current study developed these equations to create a more realistic depiction of fracture propagation. Hence, an accurate fracture path has been presented.
