1. A system for use in a well treatment operation, comprising:
a manifold configured to combine fluid flows into a well treatment fluid for delivery into a wellbore;
a blender system in fluid communication with the manifold to deliver a first fluid flow comprising water and proppant; and
a mixer system in fluid communication with the manifold to deliver a second fluid flow comprising water mixed with a dry powder material, the mixer system comprising:
a first Venturi mixer powered by a first flow of drive fluid pumped through a first Venturi to create suction at a first suction inlet positioned to draw in a flow containing the dry powder material so as to discharge a mixture of the drive fluid and the dry powder material through a first outlet; and
a second Venturi mixer powered by a second flow of drive fluid pumped through a second Venturi to create suction at a second suction inlet connected in fluid communication with the first outlet, the second flow of drive fluid being combined with the mixture discharged from the first outlet to create the second fluid flow, the second fluid flow being discharged from the second Venturi mixer through a second outlet to allow continued movement of the second fluid flow to the manifold,
wherein the mixer system further comprises a control valve positioned to enable control over the second flow of drive fluid to the second Venturi mixer.
