Abstract
Analysis of chemical and physical properties of drilling and formation fluids associated with pulse power drilling operations that are performed in a borehole extending below a surface into one or more layers of formation material are conducted to determine one or more properties associated with the formation material and/or the drilling and formation fluids.
Claims20
A method comprising:
- performing a chemical analysis on a sample of drilling fluid to determine a level or a concentration of one or more chemical compounds and/or chemical elements present in the sample of drilling fluid and formed as a result of an interaction of at least a portion of the sample of drilling fluid with an electrical discharge generated by an electrode of a pulse power drilling apparatus operating in a borehole and that are indicative of a fluid influx or a fluid loss occurring in the borehole;
- determining that at least one of the fluid influx or the fluid loss has occurred within the borehole based at least in part on the chemical analysis of the sample of drilling fluid.
A system comprising:
- a pulse power drill string configured to be positioned in a borehole formed in a subsurface formation, wherein the pulse power drill string comprises a drill bit with one or more electrodes to periodically emit an electrical discharge to drill the borehole;
- a sample extractor configured to collect a sample of a drilling fluid that circulated down the borehole and that has interacted with the electrical discharge;
- an analysis system configured to determine a level or a concentration of one or more chemical compounds and/or chemical elements present in the sample of drilling fluid and formed as a result of the interaction of the sample of drilling fluid with the electrical discharge and that are indicative of a fluid loss and/or a fluid influx having occurred within the borehole;
- a processor;
- and
- a computer-readable medium having instructions stored thereon that are executable by the processor to cause the processor to,
- determine that at least one of a fluid loss and a fluid influx had occurred within the borehole based at least in part on a determination of the level or the concentration of the one or more chemical compounds and/or chemical elements present in the sample of drilling fluid as determined by the analysis system.
4 more elements
A non-transitory, computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:
- performing a chemical analysis on a sample of drilling fluid to determine a level or concentration of one or more chemical compounds and/or chemical elements present in the sample of drilling fluid and formed as a result of an interaction of at least a portion of the sample of drilling fluid with an electrical discharge generated by an electrode of a pulse power drilling apparatus operating in a borehole and that are indicative of a fluid influx of formation fluid into the borehole;
- determining that at least one of the fluid influx or a fluid loss has occurred within the borehole based at least in part on the chemical analysis of the sample of drilling fluid.
