Numerical Modeling of the Flow of Fluids and Energy in EOR Injection Wells Using PROSPER

This report is written to mainly discuss about the final year project entitled “Numerical Modeling of the flow of fluids and energy in Enhanced Oil Recovery (EOR) injection wells using PROSPER”. Oil and gas industries are looking for new ways to maximize their production and at the same time maximize their profit. One of the main focuses of all the oil and gas industries is increasing the recovery of the oil and gas using Enhanced Oil Recovery (EOR) method. Steam injection is one of the EOR methods that have been given higher priority by oil and gas industries. Many researchers have done the study on the heat losses along the wellbore during the steam injection. In this project, heat losses have been calculated using PROSPER software which in one of the commercial software used by oil and gas industries. The main purpose of this study is to calculate the heat losses, pressure losses, temperature losses, and steam quality changes along the wellbore during steam injection. Increment or decrement of the fluid temperature will directly affect the energy that going to be transferred to the production fluid. Wellbore cement failure due to the higher temperature along the wellbore can be avoided once the heat losses are known. The results that have been obtained from this project work clearly shows the amount of heat losses to the formation and how it affect steam quality, temperature, pressure of injected steam. Greater heat losses can be avoided using insulation material in the wellbore. The optimum injected steam temperature and pressure as well as steam quality at the wellhead can be calculated once the amount of energy of the steam is known at the bottomhole. Cement failure can be prevented by using the proper cement to counter the effect of the heat. Taking into the consideration the effect of friction and slippage effect between phases, PROSPER can accurately calculate the heat losses that occurs in the wellbore.
