Abstract
Various apparatus or methods are arranged to determine a first isotope ratio of an effluent drilling fluid, wherein the effluent drilling fluid is a drilling fluid after the drilling fluid has interacted with a plasma discharge produced via one or more electrodes of a drill bit of a pulsed power drill string disposed in a borehole. A second isotope ratio is estimated based on the first isotope ratio and a downhole reaction generated by the plasma discharge.
Claims20
A method comprising:
- determining a first isotope ratio of an effluent drilling fluid, wherein the effluent drilling fluid is a drilling fluid after the drilling fluid has interacted with a plasma discharge produced via one or more electrodes of a drill bit of a pulsed power drill string disposed in a borehole;
- and
- estimating a second isotope ratio based on the first isotope ratio and a downhole reaction generated by the plasma discharge.
A system comprising:
- a pulsed power drill string disposed in a borehole, the pulsed power drill string comprising a drill bit having one or more electrodes;
- drilling fluid circulating within a flow path extending into and out of the borehole;
- one or more processors;
- and
- a machine-readable medium having instructions stored thereon that are executable by the one or more processors to cause the one or more processors to
- determine a first isotope ratio of an effluent drilling fluid, wherein the effluent drilling fluid is the drilling fluid after the drilling fluid has interacted with a plasma discharge produced via the one or more electrodes;
- and
- estimate a second isotope ratio based on the first isotope ratio and a downhole reaction generated by plasma discharge.
A machine readable medium having instructions stored thereon that are executable by a computing device to perform operations comprising:
- determine a first isotope ratio of an effluent drilling fluid, wherein the effluent drilling fluid is a drilling fluid after the drilling fluid has interacted with a plasma discharge produced via one or more electrodes, where the one or more electrodes are components of a drill bit of a pulsed power drill string disposed in a borehole;
- and
- estimating a second isotope ratio based on the first isotope ratio and a downhole reaction generated by the plasma discharge.
