Abstract
In one embodiments, a method includes drilling a wellbore in a formation with a drilling tool. The method further includes receiving electromagnetic radiation using an opto-analytical device coupled to the drilling tool. The method also includes detecting a characteristic of cuttings associated with drilling the wellbore based on the received electromagnetic radiation.
Claims25
A method for drilling a wellbore comprising:
- drilling a wellbore in a formation with a drilling tool;
- receiving electromagnetic radiation using an integrated computational element of an opto-analytical device coupled to the drilling tool;
- transmitting at least a portion of the received electromagnetic radiation through the integrated computational element;
- determining a characteristic of cuttings associated with drilling the wellbore based on an intensity of the transmitted portion of the received electromagnetic radiation using a processing unit of the opto-analytical device;
- and
- characterizing a drilling condition of the wellbore based on the characteristic of the cuttings.
