Feasibility research on geostress as a new energy

Due to the huge economic value of combustible natural gas, the kinetic energy generated by gas flowing from underground to the earth’s surface is often ignored in the production process. Based on the existing oil field production data when integrated with geological, geophysical and geochemical theory, we present initial research on the feasibility of utilizing a significant and hitherto unexploited new energy source — geostress energy. This is the energy associated with the enormous geostress to discharges the natural gas (including combustible gas and non-combustible gas) from the rock pores to the earth’s surface, so that the abundant underground natural gas becomes the geostress energy carrier. Through the analysis of oil field production data, we find that vast geostress energy exists not only in high pressure self-spouting wells, but also in some abandoned wells. Then, we are able to establish that the available geostress energy is enormous in the world from estimation of the top 10 natural gas producing countries. Finally, since the utility of such a new type energy is still under the initial developing stage, we outline the future research tasks and summarize the main challenges to achieve widespread use of the geostress energy and make a sizable great contribution to reducing the exploitation of fossil energy, solving environmental pollution problems and achieving carbon neutrality.
