摘要： A method of testing an electrical submersible pump (ESP) component may include placing an ESP component in a transport assembly at a first location for transport to a second location. The ESP component may be tested or maintained while the ESP component remains in the transport assembly, before being deployed at a wellsite. The ESP components can be prepared in the transport assembly to be lifted (including placement of lifting clamps) to run in hole. In various embodiment, the transport assembly may comprise the ESP component and a transport basket configured for stacking multiple transport assemblies.

摘要： A cement slurry including graphene, a cementitious material, and water; the graphene comprises bioderived renewable graphene (BRG). The cement slurry can comprise from about 0.01 to about 20, from about 0.1 to about 15, from about 0.5 to about 5 percent graphene by weight of cementitious material (% graphene bwoc). The cement slurry can have enhanced stability, as evidenced by a uniform density of the slurry and a reduction in free fluid, according to API 10B-2, relative to a same cement slurry absent the graphene.

摘要： Systems and methods are provided for a wet-mate connector assembly that can include a stiffening material and a dielectric grease retainer for preventing the extrusion of dielectric grease during a wet connect. The wet-mate connector assembly can include a male portion and a female portion that can receive the male portion to form an electrical connection with the male portion. The wet-mate connector assembly can also include a dielectric grease retainer that can be positioned near the male portion and the female portion for retaining dielectric grease extruded from a contact chamber when the female portion receives the male portion. The dielectric grease retainer can seal and insulate the contact chamber. The contact chamber can be defined by an outer diameter of the male portion and an inner diameter of the female portion. The male portion and the female portion can include a stiffening material and an insulating material.

摘要： This disclosure presents a method and process to improve the accuracy of the calculations for true vertical depth and Eastings and Northings pair of a borehole while drilling operations are in progress. The method utilizes continuous survey parameters that are collected while drilling operations are in progress, and that have been collected between two neighboring stationary survey parameters. The stationary survey parameters are assumed to be ground truth and are fused with an invertible solution to a low order polynomial to generate the true vertical depth and an Eastings and Northings pair at each continuous survey location. An objective function can be used to optimize and solve the polynomial. The method can be performed on a well site controller, a geo-steering system, a bottom hole assembly, or other computing system capable of receiving the collected measurements, performing the method steps, and communicating the resultant borehole position parameters to other systems.

摘要： A fluid sampling tool may include a fluid characterization device consisting of a densitometer, a viscometer, or a vibrating element, or a combination thereof and a polymer disposed in or around the fluid characterization device, wherein the polymer volume, density, or viscosity changes with an ionic stimulus. The fluid characterization device may be located within a bypass flow line of the sampling tool. A method of measuring pH and a method of monitoring at least two analytes at the same time using the fluid characterization devices are also discussed.

摘要： A seal mechanism for an electric submersible pump (ESP) assembly comprising a graphite ring installed on a first component with an installation configuration and a sealing configuration. The graphite ring is installed on an external sealing surface of a first component. An internal sealing surface of a second component is aligned with the graphite ring. An activation force transitions the graphite ring from the installation configuration to a sealing configuration wherein the graphite ring forms a seal to the external sealing surface of the first component and the internal sealing surface of the second component.

摘要： Systems and methods of separating multiphase flows in a flowline of a downhole fluid sampling and analysis tool, measuring target ions in the water phase, and separating between formation water and injection water are described. The system to separate the multiphase flows includes a three-dimensional barrier permeable to water and repelling oil and/or drilling mud filtrate into at least one bypass channel within the flowline of the downhole fluid sampling and analysis tool. For instance, the system to measure the targeted ions includes the system to separate the multiphase flows and an optical sensor, wherein the three-dimensional barrier has an aperture inside the three-dimensional barrier to let a light from an optical sensor go through perpendicular to the flowline.
