Abstract A significant portion of wells in Argentina are completed in 5½″ casings, these wells contain multiple production zones and are measured depth ranged from 3,000 to 10,000 ft. Most of the ESP applications are set between and below the production zones, in order to cool the system properly, shrouds are often used, but the limitation arises in high-flow operations due to the pressure drop in the shroud due to the reduced annular space, thereby, impeding efficient exploitation of the well. The intake bypass system creates two flow paths, one intake within the shroud and one above the shroud, this guarantees a production flow free of pressure losses, dividing the total flow, reducing the flow speed that passes around the motor and taking away the risks of shroud collapsing due to high pressure differential. The Intake Bypass has two directional holes for avoiding erosion in the internal components and allowing a hydraulic balance such that the fluid derived through the shrouds guarantees the system cooling. It was performed the installation in a well in the South of Argentina and in the short term, it has accomplished the project main objectives. An increase in production of 140% was recorded, comparing with previous installation. Furthermore, the fluid level over the pump (FLOP) was reduced by about 50%, optimizing well production. Simulations have predicted that 62% of the fluid is produced through the Intake Bypass and, the other 38% flows through the inside of the shroud, having an average speed of more than 2.5 ft/sec around the motor, cooling the system efficiently with a controlled heat rise that is within 10 deg C (T motor – T intake). This is supported by the registered temperatures in the downhole sensor (intake and motor); which are around the normal values for the ESP standard application in the field and correspond to the performed simulations. The first pilot installed is still in evaluation. The Intake Bypass application is presented as a novel solution to produce high flows in reduced casing diameters, where the ESP is set between or below the production zones, forcing the usage of cooling systems such as the shrouds. In addition to that it results in energy savings by not forcing the system with an over elevation height that compensates for the loss of load.
