摘要： Corrosion and/or calcium scale deposition on a surface in contact with corrosion forming components and/or scale forming components within a subterranean formation may be decreased, prevented, and/or inhibited by contacting the surface with at least one protein. The protein(s) may be or include, but is not limited to, at least one aspein protein, at least one aspolin protein, at least one dentine protein, at least one DRICH-1 protein, at least one nacrein protein, at least one SMDT-1 protein, derivatives thereof, fragments thereof, mimetics thereof, and combinations thereof. The surface may be or include, but is not limited to a metal surface, a plastic surface, a ceramic surface, a painted surface, a coated surface, and combinations thereof.

摘要： A submersible well pump assembly has a communication path for communicating motor lubricant to an interior of a pressure equalizer. A check valve passage with a check valve leads from the communication path to a pressure equalizing chamber. A dip tube has a dip tube inlet at the check valve passage below the check valve and a dip tube outlet in the pressure equalizing chamber. The dip tube is filled with motor lubricant to retard migration of well fluid from the pressure equalizing chamber into contact with the check valve.

摘要： An earth-boring tool includes a body, a plurality of blades attached to the body and extending at least to a nose region of the earth-boring tool, a first rotatable cutting structure assembly coupled to the body, and a second rotatable cutting structure assembly coupled to the body. The first rotatable cutting structure assembly includes a first leg and a first rotatable cutting structure rotatably coupled to the first leg. A first cutting profile of the first rotatable cutting structure extends at least from a gage region of the earth-boring tool and at least partially through a cone region of the earth-boring tool. The second rotatable cutting structure assembly includes a second leg and a second rotatable cutting structure rotatably coupled to the second leg. A second cutting profile of the second rotatable cutting structure extends only from the gage region of the earth-boring tool and to an innermost boundary of a nose region of the earth-boring tool.

摘要： A gauge assembly deployable from a surface system into a subsurface system includes a device housing having a first end, a second end, and an intermediate portion extending therebetween. The intermediate portion includes an outer surface and an inner surface that defines a device receiving zone. A device is arranged in the device receiving zone. The device includes one of a pressure sensor, a temperature sensor, and a communication device. A control line is connected to the device and extends from the second end of the device housing to the surface system. A guide member is mounted to the first end of the device housing. The guide member includes a tapered end section that promotes deployment into the subsurface system.

摘要： An apparatus for sensing pressure and temperature includes: a hollow glass tube; a first optical fiber having an end disposed into a first end of the tube; a second optical fiber being disposed in a second end of the tube, the second optical fiber having a first solid core section followed by a hollow core section followed by a second solid core section, a first gap formed between the first and second optical fibers, a length of the first solid core section forming a second gap, and a length of the hollow core section forming a third gap; an optical interrogator that transmits light at various wavelengths and measures an intensity of reflected light due to the first gap, second gap, and third gap as a function of frequency to provide interrogation data; and a processor that matches the interrogation data to reference data to estimate the pressure and/or temperature.

摘要： Systems and methods for distributed downhole sensing of operating parameters in an ESP utilizing MEMS sensors. In one embodiment, an ESP is installed in a well. The ESP has a pump, a gas separator, a seal section and a motor. Multiple MEMS sensors are positioned within one or more of the ESP components. Each of the MEMS sensors has a sensor component and on-board circuitry that are formed on a substrate. Each MEMS sensor's sensor component senses a corresponding operating parameter and provides sensed information to the on-board circuitry, which processes the received sensor signal as needed and provides the processed information at an output of the MEMS sensor. The outputs of the different MEMS sensors can be networked together, and the sensor information for the different operating parameters can be communicated to equipment at the surface of the well via a common electrical line.

摘要： Unwanted oscillations of a drill string while a borehole is being drilled are limited by adjusting a drilling parameter. Measurements related to oscillations of the drill string can be extrapolated by calculation to a position of interest along the drill string using a mode identified from one or more determined modes and a stability criterion that models the drill string. The stability criterion includes a specific modal damping for each of the one or more determined modes. The position of interest may correspond to a location of a tool or component that may be damaged by the unwanted oscillations. If the tool or component can be damaged by the oscillations as calculated, then the drilling parameter is adjusted to limit those oscillations.
