Abstract:
A method of controlling fluid flow through a circulation valve disposed in a borehole includes flowing a fluid at a first flowrate through a first jet and a second jet disposed in a throughbore of a sliding sleeve disposed in a housing of the circulation valve, flowing the fluid at a second flowrate through the first jet and the second jet to actuate the sliding sleeve from a first position to a second position, and flowing the fluid from the throughbore of the sliding sleeve through a housing port of the housing in response to actuating the sliding sleeve from the first position to a second position.
