An electric submersible pump system for use in a wellbore includes a pump; a motor protection component having an oil chamber and an wellbore fluid chamber; a motor component, the motor component including oil and being fluidly coupled to the oil chamber of the motor protection component; and a chemical chamber that includes a neutralization chemical. The neutralization chemical includes a scale inhibitor. The chemical chamber is configured to contact fluid from the wellbore with the neutralization chemical and is fluidly coupled to the wellbore fluid chamber of the motor protection component. The pump is configured to be driven by the motor component. A chemical chamber and a method for operating an electric submersible pump are also disclosed.

An electrical submersible pump (ESP) for use in a high viscosity pumping system includes a pump shaft, at least one rotating impeller including an impeller hub and one or more impeller vanes projecting from the impeller hub. Each of the one or more impeller vanes includes an impeller vane edge, and at least one stationary diffuser positioned below the at least one rotating impeller. A diffuser includes a diffuser hub and a diffuser shroud including a diffuser shroud surface. The impeller vane edge and the diffuser shroud surface are separated only by a clearance gap.

An armrest assembly includes an armrest and a lid mounted on the armrest for relative rotational movement between a closed and open positions. The lid includes a handle cradle with handle guides on opposed sides and an intermediate inner guide. A handle is located in the handle cradle for relative movement between a latch position and a release position. The handle includes a latch. The latch retains the lid in the closed position when the handle is in the latch position. The handle includes a clip that engages a slot on the lid to retain the handle in the handle cradle. The handle also includes guide channels on opposed sides. The guide channels engage the handle guides. The handle includes an intermediate inner guide space. The inner guide space engages the inner guide. The armrest assembly also includes a spring that biases the handle into the latch position.

Disclosed is a low impurity content caspofungin pharmaceutical composition and a method for preparing the low impurity content caspofungin pharmaceutical composition. The caspofungin pharmaceutical composition comprises the compound of formula I and/or a pharmaceutically acceptable salt thereof, in combination with a saccharide protective agent(s) and an amino acid(s). The caspofungin pharmaceutical composition is prepared by dissolving the saccharide protective agent and the amino acid into water or a suitable buffer solution; adding the caspofungin compound and dissolving it; filtering the solution and lyophilizing.

Low impurity content caspofungin preparation, method for preparing same, and use thereof

An electric submergible pumping system that includes a pump having a pump discharge; a motor; a power crossover assembly including a top flange having a generally circular opening in the center, an upper tubular portion connected to the top flange portion, a lower tubular portion including two generally rectangular-like shaped windows for intake suction for crude oil, a lower flange having a circular shape connected to the lower tubular portion. The top flange, the upper tubular portion, the lower tubular portion, and the lower flange are one unit, each having three adjacent holes passing there through in alignment. A first support leg includes a vertical extension from the lower flange to the upper tubular portion. Three electrical conductors, each disposed adjacent to each other, pass through the three adjacent holes for electrical connection to the motor.

The present invention provides a medicinal composition containing micafungin or a pharmaceutically acceptable salt thereof and trehalose as a stabilizing agent.
