Borehole measurement method and system

A method for measuring a borehole using a measurement device disposed within the borehole, the method comprising:

• generating, by one or more sensors of the measurement device, first measurement data of the borehole, wherein the measurement device operates in a first operational mode and moves in a first movement along a path within the borehole, and in a direction heading into the borehole;
• processing the first measurement data to generate region of interest (ROI) data indicating:
• (i) one or more geological ROIs within the borehole;
• and (ii) one or more corresponding operational mode parameters to enable the measurement device to measure the borehole;
• determining a second operational mode of the measurement device based on the ROI data;
• and
• generating, by the one or more sensors of the measurement device, second measurement data of the borehole by operating the measurement device in the second operational mode during a second movement in the direction or an opposing direction along the path,
• wherein each operational mode determines at least one of:
• one or more speeds of the measurement device within the borehole;
• and one or more states of the one or more sensors of the measurement device.

An apparatus for logging a borehole, comprising:

• a measurement device;
• a logging device;
• and
• a controller having:
• a communications interface to receive data;
• at least one computer processor to execute program instructions;
• and
• a memory, coupled to the at least one computer processor, to store program instructions for execution by the at least one computer processor,
• wherein the logging device is configured to:
• receive a measurement device control signal from the controller;
• in response to receiving the measurement device control signal, cause the measurement device to operate within the borehole,
• wherein the measurement device is configured to:
• generate first measurement data of the borehole in response to the measurement device being caused to operate in a first operational mode, and during a first movement of the measurement device along a path within the borehole, and in a direction heading into the borehole;
• generate second measurement data of the borehole in response to the measurement device being caused to operate in a second operational mode, and during a second movement of the measurement device in the direction or an opposing direction along the path;
• and
• transmit, to the controller, the first measurement data and the second measurement data,
• wherein each operational mode determines at least one of:
• one or more speeds of the measurement device within the borehole;
• and one or more states of one or more sensors of the measurement device for generating the first and second measurement data, and
• wherein the controller is configured to:
• receive the first measurement data of the borehole;
• generate borehole evaluation data to evaluate the first measurement data of the borehole;
• determine, based on the borehole evaluation data, the second operational mode of the measurement device;
• generate the measurement device control signal to cause the measurement device to operate in the second operational mode to log the borehole;
• and
• transmit the control signal to the logging device to cause logging of the borehole by using the measurement device operating in at least the second operational mode.
