METHOD FOR PRODUCING HYDROCARBON FLUID FROM HYDROCARBON FLUID-RICH SHALE

摘要

The objective of the present invention is to provide a method for efficiently producing a hydrocarbon fluid from a hydrocarbon fluid-rich shale even under high temperature without giving an excessive load to the environment. The method for producing a hydrocarbon fluid from hydrocarbon fluid-rich shale according to the present invention is characterized in comprising the steps of excavating a horizontal wellbore in a layer of the hydrocarbon fluid-rich shale, injecting a pressurized fracturing fluid into the horizontal wellbore to fracture the hydrocarbon fluid-rich shale, taking out the hydrocarbon fluid onto the ground from the fractured hydrocarbon fluid-rich shale, wherein a biosurfactant-containing solution is used as the fracturing fluid.
