Conventional and electrical EOR review: the development trend of ultrasonic application in EOR

Abstract

A small portion of oil can be extracted during primary and secondary stages of oil production, and significant quantities of oil remain in reservoirs. Enhanced oil recovery methods are used to extract the trapped oil with high viscosity in reservoirs and improve the efficiency of the production wells. Ultrasonic-based enhanced oil recovery method has become of considerable interest to researchers in recent years. This paper mainly presents the in-depth literature review of ultrasonic wave to investigate its application development trend in enhanced oil recovery. Besides, it also presents an overview of conventional enhanced oil recovery techniques such as chemical, gas, and thermal methods and nonconventional techniques such as electromagnetic and microwave heating. The results exhibit an increasing implementation of the ultrasonic waves for oil recovery since it is an inexpensive and ecologically sound method, can be applied in any type of reservoir, protects the well against damage, prevents heat loss, and enables stimulation freely.

A Perspective Review on the Current Status and Development of Polymer Flooding in Enhanced Oil Recovery Using Polymeric Nanofluids

“…Heat-transfer model simulation is crucial in thermal oil recovery to find thermal efficiency. , Gas injection causes swelling of the oil and a subsequent reduction of the oil viscosity. Other tertiary recovery methods have also been invented like microbial, acoustic, electromagnetic, and low-salinity water flooding. , …”

A Systematic Approach for Upscaling of the EOR Results from Lab-Scale to Well-Scale in Liquid-Rich Shale Plays

“…Electrical heating techniques are utilized to improve heavy oil recovery, which is approximately 70% of total reserves in the world (Mozafari and Nasri, 2017). These methods increase the oil temperature by exciting the hydrocarbon molecules through electromagnetic heating and ultrasonic stimulations, causing a reduction in viscosity (Shafiai, 2020). Electromagnetic heating is a way to transmit heat to the reservoir to raise its temperature, with minimal heat loss to the.…”

Exploiting Microbes in the Petroleum Field: Analyzing the Credibility of Microbial Enhanced Oil Recovery (MEOR)

“…However, implementing these techniques (with the exception of MEOR) requires massive energy consumption for the generation of steam, the use of costly chemicals, a huge quantity of fresh water, and expensive equipment for their groundworks, which increases the oil price and the associated ecological risks [38]. Modern technologies, such as seismic [39] or sonic stimulations [40], and electromagnetic methods [41], are also currently being implemented. These methods are discussed in detail elsewhere, and this article focuses only on the microbial method.…”
