New Theory Explains Ultrasound Wave Propagation in Porous Rocks for Enhanced Oil Recovery
Ultrasound-based irradiation of rock formations has attracted considerable attention as a technique for enhancing heavy-oil (high-viscosity crude oil) recovery from deep underground reservoirs. However, a unified theoretical framework for wave propagation and energy dissipation in these formations remains lacking because water coexists with heavy oil within rock pores, and gas bubbles in the water respond dynamically to ultrasonic excitation, thereby creating a complex system
A comprehensive theoretical framework has been developed to explain ultrasound wave propagation in porous rocks, a crucial step for enhancing heavy oil recovery. Existing methods face challenges due to the complex interaction of heavy oil, water, and gas bubbles within rock pores. This new theory identifies three distinct wave modes and accounts for energy dissipation. It addresses the dynamic response of gas bubbles to ultrasonic excitation, creating a more unified understanding. The research aims to improve the efficiency of extracting viscous crude oil from deep underground reservoirs. This advancement could lead to more effective energy extraction techniques. It provides a vital theoretical foundation for practical applications.
