N2 - Due to the inefficiency, high price, and environmental unsafety of the conventional recovery methods, the production decrease of the oil well is an increasingly serious problem all over the world. Therefore, the need for enhanced oil recovery (EOR) techniques to recover a higher proportion of the oil has become imperative. The electrohydraulic shock waves with steep fronts and high intensity are utilized to generate micro-cracks near the oil well and enhance the permeability of the reservoir. A novel enhanced oil recovery technology based on repetitive electrohydraulic shock waves is presented in this paper. The influence of discharge modes and hydrostatic pressure on its application in oil well stimulation is studied. The paper presents experimental results and optical observation for the characteristics and the development of the streamers. The on-site experiment is carried out to evaluate the potential of the proposed method and the developed equipment. Results point out that the design of the prototype should be dependent from the hydrostatic pressure and confirms the potential of this technology to be a promising EOR method in low permeability reservoir.
