An adaptive oil stimulating device: Application for liquid-saturated reservoir

This paper presents a new electronic system that stimulate. The downwhole hydrocarbon reservoirs for oil recovery enhancements while simultaneously monitorin. The evolution of its various components. The system is modular and consists to emit ultrasonic waves of a predetermined frequency and amplitude causing vibrations int. The reservoir. This leads to a variation oy the contact angle betwee. The rock formation an. The fluids as well as to a decrease oy the capillary forces, thereby reducin. The hydraulic coefficient of friction. An integrated sensing device continuously measure. The amount of water-cut i. The reservoir using separate ultrasonic sensors. This allow. The determination oy the regions of interest that contain sufficient amount of oil. Failing to localize such regions might leat the fluid to flow towards undesirable directions. Experiments were conducted on etched core samples to evaluat. The performance oy the system under oil reservoir conditions. The corresponding preliminary results show that the rate of oil displacement increases to a such level that 74% of oil could flow out oy the core after nine (9) hours of stimulations.
