  • Method and apparatus for drill cutting analysis
    Patent number: 12012852
    Abstract: A robotic mud-logger having a slurry sampler to collect a slurry sample online from a drilling fluid circuit contemporaneous with drilling of a borehole, the slurry sample including drilling fluid and rock cuttings. A liquid separator removes drilling fluid from the slurry sample and discharges a sample of the rock cuttings. A spectrometer and other sensors perform elemental analysis of, and take other measurements related to, the sample of the rock cuttings substantially in real time with collection of the slurry sample. A system is provided for retaining stored samples in containers with identifying data.

  • Surface gas evaluation during controlled pressure drilling
    Patent number: 8899348
    Abstract: A system and method have a choke in fluid communication with a rotating control device. The choke controls flow of drilling mud from the rotating control device to a gas separator during a controlled pressure drilling operation, such as managed pressure drilling (MPD) or underbalanced drilling (UBD). A probe is in fluid communication with the drilling mud between the choke and the gas separator. During operations, the probe evaluates gas in the drilling mud from the well passing from the choke to the gas separator.
