Abstract: A mixer and method for mixing are provided. The mixer includes a housing including a fluid inlet, an additive inlet, and an outlet. The housing defines a mixing chamber in fluid communication with the fluid inlet, the additive inlet, and the outlet. The mixer also includes an impeller disposed in the mixing chamber. When rotated, the impeller pumps fluid through the fluid inlet. The mixer also includes a slinger disposed in the mixing chamber and configured to receive the fluid from the impeller and to receive an additive from the additive inlet. When rotated, the slinger slings the fluid and the additive radially outwards. The mixer further includes a flush line extending between the mixing chamber and the additive inlet. The flush line is receives, from the mixing chamber, a portion of the fluid pumped by the impeller and to deliver the portion of the fluid to the additive inlet.

Abstract: An apparatus for extending the operational flow rate range of a turbine is described herein. Two or more removable sleeves may be used to change the cross-sectional area of a turbine. Each removable sleeve may define or eliminate the stator gap between a stator blade tip and an inner wall of the removable sleeve and a rotor gap between a rotor blade tip and an inner wall of the removable sleeve. A movable sleeve may be disposed in the turbine and may move between a first position and a second position in response to changes in the pressure differential across the turbine. The movable sleeve may define or eliminate a stator gap between a stator blade tip and the inner conical surface of the sleeve or a hub of the turbine and a rotor gap between a rotor blade tip and the inner conical surface of the sleeve.

Abstract: An apparatus includes an inflow control device that is disposed in a well and is adapted to receive a flow. The inflow control device includes a chamber, an outlet and at least one inlet. The chamber has a first end, a second end, and a cross-section of the chamber decreases along a length of the chamber. The outlet is disposed at the second end of chamber. The inlet has a cross-sectional dimension and is adapted to, in response to the received flow, inject a flow into the chamber near the first end of the chamber such that a fluid flow is produced inside the chamber that rotates and translates in a direction along the length of the chamber toward the outlet.

Abstract: An apparatus that is usable with a well includes a housing and a body. The housing includes an inlet and an outlet, and a fluid flow is communicated between the inlet and outlet. The body disposed inside the housing to form a fluid restriction for the fluid flow. The body includes an opening therethrough to divert a first portion of the fluid flow into a first fluid flow path; and a first surface to at least partially define the first fluid flow path. The body is adapted to move to control fluid communication through the first flow path based at least in part on at least one fluid property of the flow
