Measuring tensile strength of tight rock using electromagnetic heating
A method for determining the tensile strength of a rock sample comprising the steps of obtaining the rock sample, measuring a water content of the rock sample through a water measurement method, determining a matrix bulk modulus of the rock sample, wherein the matrix bulk modulus is determined through a matrix modulus method, heating the rock sample with electromagnetic energy such that the electromagnetic energy heats the water content in the rock sample from an initial temperature, wherein heating the water content causes a pore-water pressure of the rock sample to increase, detecting a break in the rock sample with a sensor, wherein the increase in the pore-water pressure causes the rock sample to break, wherein the break occurs at a break time, at a break temperature; and calculating the pore-water pressure through the water content, the matrix bulk modulus, and the break temperature of the water content.
