System method and apparatus for detecting downhole features

A method of identifying a geothermal reservoir of an earth formation, the method comprising:

• collecting, with one or more sensors of an instrumented engagement element located at a drill bit, while drilling a borehole of the earth formation, engagement data corresponding to an engagement of the instrumented engagement element with a wall of the borehole, wherein the engagement data includes measurements taken over portions of the wall of the borehole as the instrumented engagement element rotates with the drill bit, and wherein the engagement data includes engagement data measured at a plurality of depths in a wellbore;
• receiving, at a downhole imaging system, the engagement data from the instrumented engagement element;
• collecting, with one or more environment sensors, environment data, wherein the environment data includes measurements of a downhole environment at the plurality of depths;
• receiving, at the downhole imaging system, the environment data from the one or more environment sensors, wherein the environment data includes at least one of:
• downhole pressure, downhole fluid flow, or downhole temperature at the plurality of depths;
• mapping, at the downhole imaging system, the engagement data to the environment data to generate mapped engagement data, wherein the mapping includes associating the engagement data at the respective depths of the plurality of depths to the corresponding environment data at the respective depths;
• identifying the geothermal reservoir and one or more geological features of the geothermal reservoir based on the mapped engagement data, wherein at least one of the one or more geological features is a crack or a fracture in the earth formation, wherein identifying the geothermal reservoir and the one or more geological features is based on detecting a change in the environment data, and wherein the change in the environment data is at least one of an increase in the downhole temperature or an increase in the downhole pressure;
• determining one or more adjusted drilling parameters based on the identified geothermal reservoir and the one or more geological features of the geothermal reservoir;
• and
• drilling the borehole based on the adjusted drilling parameters.
