Systems, methods and devices for analyzing a sample of fluid extracted from a hydrocarbon-producing geological formation to detect a quantitative amount of hydrogen sulfide or disclosed. The systems methods and devices involve including a scavenger within a sample compartment to react with the hydrogen sulfide therein. The concentration of hydrogen sulfide in the sample may be derived as a function of the amount of scavenger remaining in the sample after reaction with hydrogen sulfide, an amount of byproduct of a reaction between the scavenger and the hydrogen sulfide, or an amount of hydrogen sulfide as measured following a secondary reaction that releases the hydrogen sulfide from the scavenger.

The invention is a method for the exploitation and/or monitoring of an underground formation having at least one reservoir comprising water, at least one gas species of interest and at least one atmospheric isotope of at least one rare gas present in dissolved form in the water of the reservoir. The method includes at least (1) taking at least one gas sample at the level of at least one collection of water from the reservoir, the collection being at the surface and the sampling being carried out to avoid any contamination with the air; (2) measuring at least the concentration of at least the gas species and the concentration of at least an atmospheric isotope of the rare gas in the gas sample; (3) determining the concentration of the gas species of interest dissolved in the water of the reservoir by a model.

To estimate a state of a natural resource in pipeline equipment during extraction in an oil field, provided is an apparatus including a data acquiring section that acquires measurement data, measured by a measurement device, indicating a state of a natural resource that is a fluid flowing through an extraction network for extracting the natural resource; a state estimating section that estimates the state of the natural resource at least at one location differing from a location where the measurement device is provided in a flow path of the extraction network, using the measurement data and a model of the extraction network; and a margin calculating section that calculates a margin until flow path blocking matter is generated in the extraction network, based on the estimated state of the natural resource.

Moisture separation systems and condensation devices for gas extracted from drilling fluids while drilling are provided. The condensation devices include a body having a first end and a second end and an exterior wall defining an interior surface, an interior passage providing a connection from the first end to the second end, and an angled support path within the interior passage, the angled support path extending from the interior surface and angled with respect to gravity. The angled support path is configured to direct a condensate away from the interior surface by the operation of gravity.

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.

Systems and methods for maintaining operation of gas sampling equipment utilized in oil and gas operations, wherein an isolation valve is deployed along a gas extraction conduit in order to isolate a gas analysis system from pressurized fluid that may be injected into the extraction conduit from a fluid delivery system. A parameter of the flow stream, such as a particular gas content or the presence of a bump gas, may be monitored. A change in the parameter may be indicative that debris is inhibiting fluid flow into the extraction conduit. When such a condition is suspected, gas sampling is suspended and the valve between the gas analysis system and the intake of the extraction conduit is closed. With the valve closed in order to protect the gas analysis system, a fluid is injected into the extraction conduit from the fluid delivery system.

A frequency sensor comprises a surface functionalized with a reactant sensitive to an analyte and a vibration detector coupled to the functional surface to detect a frequency of a fluid having the analyte and located on the functional surface during vibration thereof. The frequency sensor comprises a measurement circuitry coupled to the vibration detector to determine a frequency shift over time of the detected frequency, wherein the frequency shift corresponds to the presence of the analyte which has reacted with the reactant.

Method for determining an extraction efficiency of at least one volatile species contained in a drilling mud, the method including: housing a test mud in a first closed container; determining a test parameter representative of a ratio between a first portion of at least one first volatile species, which is absorbed by the test mud, and a second portion of the first volatile species, which is not absorbed by the test mud, the second portion of the first volatile species being measured in a headspace of the first closed container; housing a drilling mud in a second closed container, the drilling mud containing at least one second volatile species, the second volatile species being substantially the same as the first volatile species; determining an operating parameter representative of a quantity of the second volatile species released by the drilling mud in the second closed container, wherein the quantity of the second volatile species is measured in a headspace of the second closed container; determining, as a function of the operating parameter and the test parameter, an absorption parameter indicative of a quantity of the second volatile species in the drilling mud; determining, as a function of the absorption parameter, an extraction efficiency of the second volatile species from the drilling mud.
