摘要： The disclosure relates to a device for analyzing at least a flow of 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, each comprising at least a detector for measuring at least a parameter relative to a content of at least a gas compound in the flow of gas. The chassis comprises a core connector having power, communication and fluid outputs, each of the analysis modules having a module connector complementary to the core connector. The complementary core and module connectors are configured to form a removable connection. The device is configured to obtain a measurement from the detector of the first analysis module when the first analysis module is connected to the chassis via the core connector and to obtain a measurement from the detector of the second analysis module when the second analysis module is connected to the chassis via the core connector.

- providing (116, 118), during a first period, a set of measurement values (va i,m ; vc j,m ) representative of a volume of drilling fluid in each of the pits belonging to a predetermined group (112, 113) ; then
- based on volume measurement values, identifying (148) volume variations occurring during the first period for the pits of the predetermined group, each volume variation of a pit being associated with a volume variation period ;
- calculating (162), for each measuring time (t m ), a corrected cumulated volume of drilling fluid (V' m ) for the pits of the predetermined group, based on the identified volume variation occurring in at least a sub-group (113) of the predetermined group, and
- estimating (163) a first value (A m ) for a gain or loss of drilling fluid at a measuring time (t m ) by comparing the corrected cumulated volume (V' m ) with an expected value (V 0 ).

摘要： Systems and methods are provided for estimating and/or using drilling efficiency parameters of a drilling operation. A method for estimating drilling efficiency parameters may include using a borehole assembly that includes a drill bit to drill into a geological formation. A number of measurements of weight-on-bit and torque-on-bit may be obtained during a period in which weight-on-bit and torque-on-bit are non-steady-state. The measurements of weight-on-bit and torque-on-bit may be used to estimate one or more drilling efficiency parameters relating to the drilling of the geological formation during the period.

摘要： A mud gas analyzer and a well-site system using the mud gas analyzer are described. The mud gas analyzer includes at least one degasser adapted to extract gas from drilling mud passing through a flow path formed at least partially by a drill string within a well and an annulus positioned between an exterior surface of the drill string and a formation surrounding the well at a well-site, at least one gas analyzer adapted to interact with the gas extracted from the drilling mud. The gas analyzer determines an isotopic composition of a gas liberated from the drilling mud and generates a sequence of signals indicative of ratios of isotopes of a gas species liberated from the drilling mud. The computer system includes a processor adapted to execute logic to cause the processor to access information indicative of the well's and drilling tool's geometry and mud flow rates or access information from any other source providing particular locations of the well at which mixing of fractions of a gas species occurred including formation gas and recycled gas, receive the sequence of signals, and to calculate and log isotopic characteristics of the gas species entering the drilling mud at particular locations of the well within a geological formation.

摘要： Devices and methods for estimating properties of geological formations drilled with a drill bit (16) and an underreamer (18) are provided. A method according to the disclosure includes receiving a set of mixed well-logging data corresponding to a geological formation at multiple depths of a wellbore drilled using a bottom hole assembly (28) that includes a drill bit and a first underreamer. The drill bit and the first underreamer are spaced a first distance (76) apart from one another. The method includes separating the set of mixed well-logging data into first well-logging data corresponding to the geological formation at depths drilled by the drill bit (16) and second well-logging data corresponding to the geological formation at depths reamed by the first underreamer (18).

摘要： A method is disclosed and performed by collecting, by a volumetric sampler (50), a known volume of a sample from drilling fluid (28) exiting a well bore (12) penetrating a formation (14), the sample having a free gas and a dissolved gas. A first quantity of the free gas entrained in the sample is measured by a free gas detection system (52). The sample is transferred to a dissolved gas detection system (54) after the free gas in the sample is measured. The method is further performed by measuring a second quantity of the dissolved gas in the sample by the dissolved gas detection system. A total amount of one or more certain type of gas in a formation is estimated based on the first and second quantities.
