Abstract
The present disclosure relates to systems and methods for producing a fracturing gel using a preheated hydration fluid. The hydration fluid can be preheated using heat energy recycled from a different part of the operation. Recycling the heat energy can, in certain instances, reduce gel production costs and gel hydration times while improving gel yield.
Claims23
A method for producing a gel comprising:
- generating a fluid flow between an inlet and an outlet, the fluid flow at the inlet comprising a flow of hydration fluid and the flow at the outlet comprising a flow of a well injection mixture;
- elevating a temperature of the flow of hydration fluid by transferring energy from the flow of the well injection mixture to the flow of hydration fluid;
- and
- combining a flow of hydratable material with the flow of hydration fluid to form the flow of the well injection mixture.

A method comprising:
- combining a hydration fluid and a hydratable material to form a well injection mixture;
- and
- heating at least one of the hydration fluid or the hydratable material to a selected temperature using heat energy from the well injection mixture.
A system comprising:
- a flow of hydratable fluid;
- a flow of hydratable material;
- a mixer operable to combine at least a portion of the flow of hydration fluid with the flow of hydratable material to form a flow of a well injection mixture;
- and
- a first heat exchanger operable to transfer heat from the flow of the well injection mixture to the flow of hydration fluid to increase a temperature of the flow of hydration fluid.
