Abstract: A new apparatus and method within a portable Mudlogging gas detection system that determines the total amounts and various composition of an incoming mix of gases extracted from drilling fluid. The Mudlogging system consists of at least one electronic computing device, at least one infrared interferometer, and at least one other device for detecting gasses extracted from the drilling fluid. The Mudlogging system may switch from the primary gas detection means to a secondary gas detection means upon detection of a non-recoverable fault of the first gas detection means.

Abstract: A gas detection system that can parasitically utilize a mobile computing device to measure the presence and amount of gasses in a gas sample. The gas detection system can have a gas detection housing that has a local controller and at least one sensor. One or more mobile computing devices, which may be utilized as a remote controller, can be physically and electrically connected to the gas detection housing. The local controller can utilize a remote controller resident in the mobile computing device to detect one or more gasses in a gas sample with the at least one sensor.

Abstract: A liquid capture valve may have a housing that physically contacts a lid and contains a floating member. The lid can have an inlet and an outlet with the outlet positioned at an apex of a sealing surface. The floating member can be configured to seal the outlet by contacting an outlet edge in response to the housing containing a predetermined volume of liquid.

Abstract: A device and associated method can detect hydrocarbon gas with at least a control module having a plurality of different gas detection means housed in a mobile enclosure, the control module configured to activate at least two different gas detection means to provide amounts and types of gases present in a fluid.

Abstract: Assorted apparatus and methods optimize the detection of gas entrapped in drilling fluid. A mudlogging injection system can have a processor that autonomously injects sample gas into a gas chromatograph with near atmospheric pressures to optimize sample gas testing time and accuracy. The processor can autonomously detect errors, such as gas chromatograph detector drift, and conduct chromatograph adjustments to ensure accurate detection of different constituent gases entrapped in the drilling fluid.

Abstract: A mudlogging device may consist of a housing that is positioned above a ground level and proximal a wellbore. The housing can have a first interferometer and a second interferometer that are connected to a common pathway. The duel interferometer configuration may allow a gas sample to be concurrently tested by the respective interferometers.

Abstract: A system can be constructed and operated with at least a wellbore that is connected to a gas detection system. The gas detection system can house a control module, infrared sensor, and first and second pumps in a portable case. The first and second pumps may be respectively positioned on opposite sides of the infrared sensor and configured to provide uniform sample gas flow through the infrared sensor to detect multiple different types of gasses flowing from the wellbore.
