Project 1 – Evaluate operating parameters for Hydraulic Fracturing Due date: September 27, 2016
In recent years, you may have heard the term “hydraulic fracturing” in oil & gas recovery. It is responsible for significant increase in oil supply. Some attributed the oversupply of oil in the market to this new technology.1 In this project, we use our knowledge in momentum transfer or fluid mechanics to evaluate some parameters involved in operating hydraulic fracturing. What is Hydraulic Fracturing? Hydraulic fracturing (sometimes referred to simply as fracking) is a well-stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.2 This process is illustrated in Figure 1 below.
Answer the following questions. Determine the pressure requirement for the pumper truck in order to pump the mixture into the well. a. Determine what parameters will impact the pressure requirements b. Discuss different considerations that factored into your decision c. State all your assumptions Instruction ? Work in a group of 3 and write a few page summaries of the calculation. IF your hand writing is not legible, please type it up. ? Write down the names (and student IDs) of all the members in your group. ? Prepare to discuss your solution (5 minute discussion for each group) in class
