摘要： A method for determining flow rates and phase fractions within a throughbore is disclosed. The method includes providing a mixture of one or more fluids through a fluid flow path in a throughbore at a flow rate, reducing the flow rate, slidably moving a first and second sleeve along the throughbore to a first position of a plurality of positions, measuring a first and second differential pressure at the first position, calculating a first loss pressure ratio from the first and second differential pressure. The method further includes slidably moving the first sleeve and second sleeve to each of the others of the plurality of positions in succession after the first position, measuring a plurality of differential pressures and calculating a loss pressure ratio at each of the plurality of positions, and calculating a plurality of flow rates phase fractions of the fluids flowing through the fluid flow path.

摘要： A monitoring system for a drill string controlled by a drilling program may include a contactless sensor arranged to capture data at a second time. The data may be associated with a parameter at a position along a drill line associated with the drill string. The system may include a processor operatively connected to the contactless sensor. The processor may be configured to access a machine learning (ML) model that is trained using the data captured at a first time, prior to the second time, and an image analysis algorithm. The processor may be configured to identify, using the trained ML model, a condition pertaining to the drill string based on interpreting the data captured at the second time. The processor may be configured to cause an adjustment to the drilling program based on the identified condition.

摘要： In a method for diverter fracturing, a water-based fracturing fluid including non-convex particles is introduced into a hydraulic fracture of a wellbore at a first location. Each non-convex particle is formed to interlock with another non-convex particle. A diverter plug is formed in the hydraulic fracture when multiple non-convex particles interlock. Flow of another water-based fracturing fluid is diverted to a second location due to the diverter plug, forming another hydraulic fracture at the second location.

摘要： A method for an integrated process to streamline privileged access management (PAM) allows an integration of an existing PAM system with a self-service portal at the front, and an existing back-end workflow automation engine, is disclosed. In the method, a request for an elevation for an access to an application is received from a user via a self-service portal, and the request is reviewed by a PAM system administrator. Then, a process, which enables a policy of the application corresponding to a policy chosen by the user, is initiated when the PAM system administrator approves the request. Finally, a grant of the access to the application is notified to the user via the self-service portal.

摘要： A valve assembly that includes a first sensor, multiple sensors, and a system. The first sensor generates, when attached to a valve in a closed position and in a passing condition, first sensor feedback including vibration information. The multiple sensors generate second sensor feedback. The system includes one or more computers that receive the first sensor feedback and second sensor feedback and determine, as a function of the second sensor feedback, a temperature differential between an inlet of the valve and an outlet of the valve. The one or more computers compare the vibration information and temperature differential to at least one threshold, and determine that at least one of the vibration information or temperature differential satisfies the at least one threshold. The one or more computers provide, to a receiver, information including an indication of a passing condition of the valve.

摘要： Systems and methods include a computer implemented method for evaluating rock physical properties. Drilling acoustic signals are received in real time during a drilling operation through rock at a drilling location. Transformed data is generated in a frequency domain from the drilling acoustic signals. The transformed data includes frequency and amplitude information for the drilling acoustic signals. De-noised transformed data is generated from the transformed data by filtering noise including background noise generated in a recording system and top drive rotation generated traces. A lithological significant frequency range that includes de-noised significant data points is determined from the de-noised transformed data. Physical properties of the rock are determined in real time using drill bit rotation rates and the amplitudes of the de-noised significant data points.

摘要： Systems and methods for monitoring pressure in hydrocarbon wells for controlling operation of the hydrocarbon well are configured for operations comprising receiving pressure data for a well, the pressure data comprising values of a pressure in a well annulus over a period of time for a set of wells; identifying one or more anomalies in the pressure data by comparing the values of the pressure to threshold values, the anomalies in the pressure data representing an anomalous pressure condition for a well; determining, based on the one or more anomalies, a failure factor for one or more wells associated with the anomalies; and predicting, based on the failure factor, a cycle time of anomalies in the pressure conditions for the one or more wells.
