The disclosure relates to a modular device for analyzing gas extracted from a drilling fluid used for drilling a wellbore, comprising a chassis having a power supply system, a fluid distribution and regulation system, and a control module, and a first and second analysis module of different types. The analysis modules comprise a detector for measuring a parameter relative to a content of a gas compound. The chassis comprises a core connector having power, communication and fluid outputs, the analysis modules having a module connector complementary to the core connector. The complementary core and module connectors form a removable connection, easy and quick to connect. The device obtains a measurement from the detector of the first analysis module when connected to the chassis via the core connector and a measurement from the detector of the second analysis module when connected to the chassis via the core connector.

Device comprising multiple detectors for detecting a flow of gas extracted from a drilling fluid

A computer system including a processor executing processor-executable code stored in a non-transitory processor-readable medium, causing the processor to receive a signal via an input port, including data indicative of an amount of a combustion product produced by a sample of drill cuttings subjected to oxidation at a constant temperature (1000&#xb0; C. or 650&#xb0; C. 100&#xb0; C.) as a function of time and process the data according to a predetermined logic to: locate a peak in the amount of the combustion product produced at a set of instants in time; correlate the set of instants in time with the presence in the sample of an organic carbon from a contaminant or light volatile carbon molecules, organic carbon, and inorganic carbon; calculate at least one of an amount of contaminant, a total amount of organic carbon, and a total amount of inorganic carbon; and output a signal indicative of the calculated amount.
