Bottomhole assembly for geothermal field construction

A system for constructing geothermal fields, comprising:

• a coiled tubing (CT) string;
• a telemetry wire positioned within the CT string and configured to transfer power from a surface to a telemetry system;
• a bottomhole assembly (BHA) coupled to the CT string, the BHA including:
• the telemetry system configured to receive power from the telemetry wire, the telemetry system including (i) a flexible electronics board, (ii) a first battery that provides backup power to the flexible electronics board when the telemetry wire fails, wherein the flexible electronics board is configured to be bent and at least partially wrap around the first battery, (iii) a plurality of sensors, including a first sensor disposed on the flexible electronics board and one or more second sensors that are not disposed on the flexible electronics board;
• one or more processors;
• and memory coupled to the one or more processors, the memory storing instructions that, when executed by the one or more processors, cause the system to:
• facilitate deployment of the CT string including the BHA from the surface into a subsurface for drilling a geothermal borehole;
• and while drilling the geothermal borehole:
• collect telemetry data via the plurality of sensors and transfer the telemetry data from the subsurface to the surface via the telemetry wire;
• use a first portion of the telemetry data collected by the first sensor to calibrate a second portion of the telemetry data collected by the one or more second sensors to obtain calibrated telemetry data;
• update one or more operational parameters according to the calibrated telemetry data;
• and control the BHA to construct the geothermal borehole according to the updated one or more operational parameters.
