摘要： Examples of methods and systems are disclosed. The systems may include an overshot including a tubular housing comprising a bore and configured to transfer a fluid flow through the bore. The overshot may also include a rotatable housing extending in a direction of a central axis of the tubular housing. The rotatable housing may be configured to receive the fluid flow and be driven by the fluid flow to have rotational motion about the central axis. The rotatable housing may be also configured to receive a fish and rotate and displace the fish towards the tubular housing. The overshot may further include a gripping mechanism disposed within the bore and configured to receive and engage with the rotated fish. The overshot may still further include a bearing disposed between the tubular housing and the rotatable housing and configured to decouple rotational motion of the rotatable housing and the tubular housing.

摘要： Solar energy is concentrated and transferred to a heat transfer fluid, thereby heating the heat transfer fluid. The heat transfer fluid includes solid particles. Heat from the heat transfer fluid is used to melt a metal. While transferring heat to the furnace, at least a portion of the melted metal is oxidized to form steel. Heat is transferred from a first portion of the heat transfer fluid to a working fluid. The working fluid is then flowed through a turbine generator, which generates electrical power in response. A first water stream is electrolyzed using the electrical power generated by the turbine generator to produce a first oxygen stream and a first hydrogen stream. Heat is transferred from a second portion of the heat transfer fluid to a reactor that houses a recycling agent to thermochemically split a second water stream into a second oxygen stream and a second hydrogen stream.

摘要： A computer system obtains a first set of micro-computed tomography (micro-CT) data representing a rock sample obtained from a subterranean formation that includes gas-bearing sandstone. The system obtains a plurality of second sets of micro-CT data in a sequence, each representing the rock sample after a performance of a corresponding triaxial shear test on the rock sample. Performing each triaxial shear test includes applying a triaxial load force to the rock sample, and removing the triaxial load force from the rock sample. The system estimates, based on the first micro-CT data and the plurality of second sets of micro-CT data, one or more characteristics of the underground formation, including a permeability of the underground formation and/or a porosity of the underground formation. The system causes one or more resource extraction operations to be performed on the underground formation based on the one or more characteristics of the underground formation.

摘要： An apparatus to simulate biocide performance in crude oil pipeline conditions is disclosed. The apparatus includes: a reactor to simulate a two-phase crude oil pipeline which includes a crude oil phase above a water phase. The reactor has an agitator to control a flow of the water phase in the reactor in response to a motor that drives an agitation rate of the agitator. A crude oil inlet supplies crude oil to the reactor for the crude oil phase. A water inlet supplies water to the reactor for the water phase. A control circuit is configured by code to control a proportion of the water to the crude oil supplied to the reactor and to control the motor to drive a desired agitation rate of the agitator. A biocide inlet supplies biocide to the reactor. A water sample outlet enables sampling of the water phase of the reactor.

摘要： Control of a circuit breaker in a high voltage power station includes a signal processing circuit housed in the circuit breaker local control cabinet and wired in series with the circuit breaker, the signal processing circuit to receive a continuous alternating current (AC) electrical signal; determine an anticipated zero-crossing from the continuous AC electrical signal based on a comparison of an average of an instantaneous value of the AC electrical signal with a corresponding value of a direct current (DC) component of the AC electrical signal; and send, to the circuit breaker, a permissive signal to operate the circuit breaker or a blocking signal to prevent operation of the circuit breaker based on the determination of the anticipated zero-crossing.

摘要： A tractor assembly includes a toroidal shaped fluid filled membrane mounted over a body and a drive system coupled with the membrane. The drive system includes a helical flight that inverts the membrane when rotated against its inner surface. A mid-section of the body includes sleeve like portions that telescope with one another and shorten a length of the body. Fluid in the membrane is forced from the mid-section and radially expands a forward portion and into contact with an inner surface of the passage, so that when the membrane is inverted while in a passage, frictional contact between the membrane and inner surface of the passage creates a force that urges the tractor assembly through a passage.
