Abstract

Official abstract text for this publication.

A system for mixing fracturing gel includes a dry gel mixing chamber having a bladed impeller carried to rotate in the mixing chamber. The mixing chamber has a dry gel inlet and hydrating fluid inlet. A valve is fluidically coupled to the hydrating fluid inlet to automatically maintain a specified flow condition of hydrating fluid into the mixing chamber over multiple different values of the flow condition to the hydrating fluid inlet.

First claim

Opening claim text (preview).

What is claimed: 1. A method, comprising: receiving a dry gel particulate into a dry gel mixing chamber; receiving a flow of hydrating fluid into the dry gel mixing chamber and using a hydrating fluid source pump to circulate a hydrating fluid through the mixing chamber at multiple different operating pressures; and automatically maintaining a specified flow condition of the flow of hydrating fluid into the dry gel mixing chamber by adjusting a flow area through a pressure reducing valve in response to a change in the operation of the hydrating fluid source pump so that, as the hydrating fluid source pump operates at the multiple different operating pressures, the pressure reducing valve maintains a constant specified pressure of the hydrating fluid supplied into the mixing chamber. 2. The method of claim 1 , where adjusting the flow area of the flow of hydrating fluid comprises moving a valve closure using pressure from the flow of the hydrating fluid, upstream of the valve closure to adjust a pressure in a control volume and move a diaphragm coupled to the valve closure. 3. The method of claim 1 , where adjusting the flow area of the flow of hydrating fluid comprises moving a valve closure in response to a signal from a pressure sensor sensing the pressure of the flow of hydrating fluid.
