摘要： The geochemical parameters of reservoir fluid do not directly and universally correlate with the fluid type of the reservoir fluid, e.g. reservoir oil and reservoir gas. However, within an individual hydrocarbon basin, the local reservoir oils and the local reservoir gases are often geochemically distinct. Therefore, by examining various geochemical parameters for reservoir fluid samples taken from a particular region of interest, it is possible to identify region-specific thresholds for those geochemical parameters, and also to identify particular region-specific thresholds having a high degree of confidence for distinguishing between different reservoir fluid types. Advantageously, many geochemical parameters can be determined using mud-gas data, and in some cases using only standard mud-gas data. Therefore, by collecting mud-gas data when drilling a new well within the region of interest, these region-specific thresholds can be used to generate a substantially continuous and highly accurate reservoir fluid type log along a length of the well. This same technique may also be applied retrospectively to existing wells where mud-gas data was collected at the time of drilling, since at least standard mud-gas data is routinely collected while drilling.

摘要： Techniques for controlling lost circulation while drilling include while drilling a wellbore, encountering a high-loss circulation zone by a bottomhole assembly; responsive to encountering the high-loss circulation zone, releasing a first lost circulation media retained within the bottomhole assembly; and receiving a second lost circulation media, by the bottomhole assembly, from circulation fluid circulated from a topside facility.

摘要： A seawater injection system comprises a primary seawater supply line, a diverted seawater sampling line, and an online particles count monitoring system. The online particles count monitoring system is coupled to the primary seawater supply line through the diverted seawater sampling line such that a portion of a primary flow of seawater can be diverted to the online particles count monitoring system. The online particles count monitoring system comprises a diverted seawater inlet, a core plug assembly, a diverted seawater outlet, and an inlet pressure monitoring station between the core plug assembly and the diverted seawater inlet. The core plug assembly comprises a core plug and a removable particle filter. The inlet pressure monitoring station generates a particles count signal based on fluid pressure in diverted seawater moving through the diverted seawater sampling line in a downstream direction of the core plug and the removable particle filter.

摘要： Electromagnetic probes for analyzing a flowing multi-phase fluid are described herein. The probes generally use a probe assembly for measuring liquid properties in a multiphase fluid flowing in a conduit, the probe assembly comprising a first member with a probe portion and a connection portion, the probe portion having a central bore with a conductor and a pressure-resistant insulator surrounding the conductor, the conductor extending from an opening at a distal end of the probe portion into the connection portion, the connection portion having a connector coupled to a distal end of the connection portion, the connection portion having a seal face with a groove extending around the probe portion; and a second member that, when assembled, is in direct contact with the first member at the distal end of the connection portion to apply compression and to retain the first member against a wall of the conduit.

摘要： Systems and methods include techniques for using smart polymers. Units of smart polymers with per-hydrogen (pH) sensitivity are inserted into drilling fluid pumped into a well during drilling. The smart polymers are configured to be triggered by hydrogen ion concentrations. An insertion timestamp associated with each unit is stored and indicates a time that each unit was inserted. Continuous images and observed characteristics of returning mud exiting through an annulus of the well and containing the units of smart polymer are captured by a camera positioned at a sensing location and linked to the monitoring system. An estimate of pH values at a drill bit of the drilling operation is determined using the continuous images, observed characteristics, and insertion timestamps, and based at least in part on executing image processing algorithms, machine-learning models, and deep-learning models. Changes to be made to drilling parameters are suggested.

摘要： Systems and methods for performing a contamination estimation of a downhole sample comprising at least a formation fluid and/or a filtrate are provided. A plurality of downhole signals are obtained from the downhole sample and one or more of the signals are conditioned. At least two of the conditioned signals or downhole signals are fused into a multivariate dataset. From optical and density properties of the formation fluid and/or of the filtrate, a multivariate calculation is performed to generate concentration profiles of the formation fluid and the filtrate.

摘要： A tubular defines a central flow passage. A camera has an aperture and attached to an outer surface of the tubular with the aperture oriented away from the outer surface of the tubular. A lost circulation media reservoir is circumferentially surrounding at least a portion of the outer surface of the tubular. The lost circulation media reservoir is adjacent to the camera. The lost circulation media reservoir includes actuable gates along a periphery of the lost circulation media reservoir. A trigger is communicably coupled with the actuable gates and configured to actuate the actuable gates.

摘要： A method for evaluatingproductivity of a vertically heterogeneous gas reservoir considering interlayer crossflow is disclosed in the invention, and includes: (1) dividing a heterogeneous gas reservoir into multiple thin layersvertically; (2) obtaining the productivity of each thin layer according to data obtained through wireline formation test; (3) superimposing the productivity of all thin layers based on the water-electricitysimilarityprinciple to obtain the superimposed productivity of the heterogeneousgas reservoir; and (4) using an interlayer crossflow correction coefficient considering influence caused by the interlayer crossflow to obtain the corrected productivity of the heterogeneousgas reservoir. Specific to the vertically heterogeneous characteristics of the gas reservoir, a gas reservoir section is divided into several different flow units, such that a reservoir with strong heterogeneity is converted into relatively homogeneous reservoir sections, and the productivity thereof is determined using the data obtained through wireline formation test, considering the influence of the interlayer crossflow in a vertically heterogeneous reservoir on productivity prediction, which has more accurate prediction results.
