Using radio waves to fracture rocks in a hydrocarbon reservoir
First Claim
1. A method, comprising:
- forming a borehole pattern in a hydrocarbon reservoir from a surface of the hydrocarbon reservoir extending downward into the hydrocarbon reservoir, wherein the borehole pattern comprises a plurality of boreholes and the plurality of boreholes are formed in a horizontal well pattern, and wherein forming the borehole pattern comprises;
determining a fracturing radius based on a diameter of at least one borehole of the plurality of boreholes and a stimulated fracture density; and
positioning the plurality of boreholes in the borehole pattern based on the fracturing radius; and
for each of the plurality of boreholes;
transmitting an electromagnetic (EM) wave through the respective borehole;
directing at least a portion of the EM wave to rocks at a location below the surface in the hydrocarbon reservoir; and
fracturing the rocks at the location below the surface in the hydrocarbon reservoir by irradiating the rocks around the respective borehole using at least the portion of the EM wave, wherein irradiating the rocks elevates pore-water pressure in the rocks causing fracturing of the rocks.

Abstract
The present disclosure describes methods and systems for fracturing geological formations in a hydrocarbon reservoir. One method includes forming a borehole in a hydrocarbon reservoir from a surface of the hydrocarbon reservoir extending downward into the hydrocarbon reservoir; transmitting an electromagnetic (EM) wave through the borehole: directing at least a portion of the EM wave to rocks at a location below the surface in the hydrocarbon reservoir; and fracturing the rocks at the location below the surface in the hydrocarbon reservoir by irradiating the rocks around the borehole using at least the portion of the EM wave, wherein irradiating the rocks elevates pore-water pressure in the rocks causing fracturing of the rocks.
