Abstract: A localized inflow tracer (112) may be flushed from a gravel pack (104) surrounding a base pipe (102) of a production well by outwardly venting the inflow tracer. The base pipe (102) may include a non-perforated section (106) disposed adjacent to one or more perforated sections (108). A tracer carrier (110) may be disposed circumferentially about at least a portion of the non-perforated section (106) of the base pipe (102). An inflow tracer (112) may be released from the tracer carrier (110) into production fluid within the gravel pack (104) proximate to the non-perforated section (106) of the base pipe (102) such that the inflow tracer is flushed from the gravel pack (104) into individual ones of the one or more perforated sections (108) of the base pipe (102) and transported with the production fluid. The inflow tracer (112) may be prevented from being flushed directly from the tracer carrier (110) into the base pipe (102) due to a lack of permeability of the non-perforated section of the base pipe (102).

Abstract: A submersible pumping system for downhole use in extracting fluids containing hydrocarbons from a well. In one embodiment, the pumping system comprises a rotary induction motor, a motor casing, one or more pump stages, and a cooling system. The rotary induction motor rotates a shaft about a longitudinal axis of rotation. The motor casing houses the rotary induction motor such that the rotary induction motor is held in fluid isolation from the fluid being extracted. The pump stages are attached to the shaft outside of the motor casing, and are configured to impart fluid being extracted from the well with an increased pressure. The cooling system is disposed at least partially within the motor casing, and transfers heat generated by operation of the rotary induction motor out of the motor casing.
