CELL-DEVS MODELING AND SIMULATION OF ARTIFICIAL HYDRAULIC FRACTURING OF ROCKS IN BOREHOLES (WIP)

摘要

Hydraulic Fracturing is a technique used in the extraction and exploration of oil and gas. During hydraulic fracturing, a high-pressure fluid is injected into a wellbore; this fluid flows through some artificially made holes and into some rock fragments. As a result of the high pressure of the fluid, the rock fragments crack or fracture. These fractures form patterns that grow in a complicated manner. In practice, hydraulic fracturing is widely used; therefore, people and companies have a great interest in understanding the fracturing process. They aim to predict where the new fractures will be located and what the length, width and shape of the fractures will be. A model of hydraulic fracturing using the Cell-DEVS paradigm is described and implemented, discussing a discrete-event specification of such application.
