The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is a system that provides improved reservoir productivity through a novel, inexpensive, and environmentally friendly method. This method will use an electric impulse to increase reservoir permeability, and decrease industry reliance on alternative methods like hydraulic fracturing, which requires hazardous chemicals to be pumped into the subsurface. Residents in regions where fracking techniques are utilized have commonly been impacted by induced seismicity and landslides as a consequence of pumped in chemicals lubricating faults, making earth ruptures more likely to occur. Additionally, the material and operation time for reservoir stimulation techniques makes the current process expensive. The ability to increase permeability with an electric impulse will avoid the environmental concerns associated with current methods, and will proved a cost competitive reservoir stimulation solution due to a short operational time.This SBIR Phase I project proposes to develop a novel low-frequency impulse method (LFIM) that increases reservoir permeability for petroleum and geothermal applications, without requiring pumping of material into the subsurface. Fluid mobility is increased due to viscosity reduction and reservoir permeability is increased in the direction of interest from the vibrational removal of particles within sediment pores. This program will 1) simulate the processes taking place in the reservoir using computer simulation model, 2) perform experimental analysis of the effects of the electric treatment on different core samples, and 3) determine applicability of the method to different types of the reservoirs located in the United States. Therefore, this project will identify the optimum sites, where LFIM can boost geothermal performance and oil & gas production.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力是一个系统，通过一种新颖，廉价且环保的方法可提高储层生产率。该方法将使用电脉冲来增加储层渗透性，并减少行业对诸如液压压裂等替代方法的依赖，这需要将危险化学物质泵入地下。在化学物质润滑断层中抽水，通常会受到诱发的地震性和滑坡的影响，通常会影响压裂技术的地区的居民，这使地球破裂更可能发生。此外，储层刺激技术的材料和操作时间使当前的过程变得昂贵。 The ability to increase permeability with an electric impulse will avoid the environmental concerns associated with current methods, and will proved a cost competitive reservoir stimulation solution due to a short operational time.This SBIR Phase I project proposes to develop a novel low-frequency impulse method (LFIM) that increases reservoir permeability for petroleum and geothermal applications, without requiring pumping of material into the subsurface.由于粘度降低，流体迁移率增加，并且储层渗透率在感兴趣的方向上增加了沉积物孔内颗粒的振动。 该程序将使用计算机模拟模型模拟在储层中发生的过程，2）对电处理对不同核心样品的影响进行实验分析，3）确定该方法对位于美国的不同类型的储层的适用性。 因此，该项目将确定最佳站点，LFIM可以在这里提高地热绩效和石油和天然气的生产。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
