A diffuser for a jet pump of a separator comprises an inlet defining a first flow area; an outlet in fluid communication with the inlet through which fluid exits the diffuser, in which a flow path extends from the inlet to the outlet, and in which the outlet defines a second flow area greater than the first flow area so that a velocity of fluid flowing through the inlet is greater than a velocity of fluid flowing through the outlet; and a communication port extending through a wall of the diffuser with an inlet in communication with an interior of the diffuser and an outlet in communication with an exterior of the diffuser, in which the communication port inlet is between the diffuser inlet and the diffuser outlet, so that contaminants separated from the fluid stream are removed through the communication port.

A device for evacuating a film chamber using a pump system that comprises at least two vacuum pumps, designed to evacuate the film chamber alternately. A suction capacity of the first vacuum pump is greater than that of the second vacuum pump and the final pressure achievable by the first vacuum pump is less than that of the second vacuum pump.

A jet pump for oil production involving extraction by hydraulic lift and consists of jet pump integrally redesigned so that it is traversed by a cable for the control of the recorders of the production variables of the oil well. This control can be performed from the surface, enabling the collection of data related to measurements such as pressure, temperature and flow, both in static conditions of the well, i.e. when the well is not pumping, and in dynamic conditions, i.e. when the well is in production, and also have the security of the recovery of recorded data and measurement tools, known by its acronym MPLT (Memory Production Logging Tools), to determine the productive status of the well and make timely decisions in the management and administration of the same.
