摘要： Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. In some embodiments, OBM filtrate contamination may be determined from downhole saturation pressure measurements during pumpout of a fluid.

摘要： Systems and methods of the present disclosure generally relate to correcting isotope ratio calculations during wellbore operation. A method for correcting isotope ratios during a wellbore operation, comprising receiving a flow-in fluid sample from a wellbore; receiving a flow-out fluid sample from the wellbore; passing each sample to an analytical instrument operable to determine isotopes in each fluid sample; outputting a signal intensity or signal area; assigning a depth to the signal intensity or the signal area; and determining a corrected isotope ratio by subtracting a signal for the flow-in fluid sample from a signal for the flow-out fluid sample.

摘要： Tools, processes, and systems for in-situ fluid characterization based on a thermal response of a fluid are provided. The thermal response of a downhole fluid may be measured using a downhole thermal response tool and compared with thermal responses associated with known fluids. The properties of the downhole fluid, such as heat capacity, diffusivity, and thermal conductivity, may be determined by matching the thermal response of the downhole fluid with a thermal response of a known fluid and using the properties associated with the known fluid. The composition of the downhole fluid may be determined by matching the viscosity of the downhole fluid to the viscosity of known fluid. A downhole thermal response tool for cased wellbores or wellbore sections and a downhole thermal response tool for openhole wellbores or wellbore sections are provided.

摘要： An oil condition estimation apparatus to be applied to a vehicle in which oil is agitated by a rotator includes a storage device and an execution device. The storage device stores mapping data for defining mapping. The mapping includes, as input variables, a speed variable indicating a rotation speed of the rotator, and a pressure variable indicating a pressure of the oil, and includes, as an output variable, an air bubble variable related to air bubbles contained in the oil. The execution device executes an acquisition process for acquiring values of the input variables, and a calculation process for calculating a value of the output variable by inputting, to the mapping, the values of the input variables acquired through the acquisition process.

摘要： A device includes a housing having a bore formed axially therethrough. The housing includes a stop that protrudes radially inward proximate to a lower end of the housing. The device also includes a lower piston positioned in the bore. The lower piston is configured to move axially within the bore in response to a pressure differential across the lower piston. The lower piston is prevented from passing out through the lower end of the housing by the stop. The lower piston has a lower piston hole formed therethrough. The device also includes an upper piston positioned in the bore. The upper piston is configured to move axially within the bore in response to a pressure differential across the upper piston. The upper piston has an upper piston hole formed therethrough. The device is configured to receive a fluid in the bore, between the upper and lower pistons.

摘要： Methods and apparatus for examining a material are provided. One example method generally includes disposing the material in a dielectric contrast analysis structure, wherein the dielectric contrast analysis structure comprises a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance, wherein the material is disposed in one or more of the plurality of receptacles; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting resultant radiation from the exposed dielectric contrast analysis structure; and analyzing the detected resultant radiation to estimate at least one of a phase fraction and a phase distribution in the material. One example system generally includes an electromagnetic radiation source; a dielectric contrast analysis structure comprising a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance for receiving the material; and an electromagnetic radiation detector, wherein the analysis structure is between the radiation source and the detector.

摘要： A device for testing the three-phase saturation of oil, gas and water in a high-temperature and high-pressure planar model includes a displacement pump, a confining pressure pump, a back pressure pump, containers, a planar model system, a data acquisition system, a back pressure valve and an oil-gas separator. The planar model system includes a planar model, an autoclave body, a heating temperature-controlling system, a Y-axis direction stepping motor, a X-axis direction stepping motor and an acoustoelectric detector. A method for testing the three-phase saturation of oil, gas and water by using the device includes calibrating three-phase saturation of oil, gas and water to a rock core, preparing a formation water sample and a crude sample, regaining the original formation conditions of the planar model, simulating the depletion or displacement process of oil reservoirs, performing linear ultrasonic-and-resistivity-scanning test on planar model, determining the three-phase saturation distribution of oil, gas and water.

摘要： Systems and methods include a computer-implemented method for predicting fluid holdups along the borehole or the pipe on surface and to perform fluid typing and fluid properties characterization. Acoustic waves are transmitted by an array of acoustic wave transducers. Each transducer is configured to transmit acoustic waves at a different frequency. The acoustic waves are received by an array of acoustic wave receivers fixed on the bow centralizer on the tool used in the borehole. Each receiver is configured to receive only the given frequency of a given transducer, forming a receiver-transducer pair for the given frequency. Acoustic speeds measured at each given frequency and analyzed. A model is generated based on the analyzing. The model is configured to predict fluid holdups across the borehole and to perform fluid typing and fluid properties characterization in one phase, two phase, and three phase applications of gas, oil, and water.
