- the fracturing fluid can be prepared using return water, production water, sea water, fresh water or mixtures thereof, to hydrate a gelling agent and form a viscous aqueous fluid. To promote adequate viscosity for increasing depths of wells, they can be incorporated into
- Billing fluids buffers and crosslinking agents such as compounds capable of fiberation of borate ions.
- Fracturing fluids crosslinked with borates based on return water, production water, seawater, fresh water or mixtures thereof perform satisfactorily in low to medium temperature fracturing applications, up to a range of 90 to 120 ° C (200 to 250 ° F).
- the pH required to form a sufficiently crosslinked gel is in a range of 8.5 to 9.5.
- a sufficiently crosslinked gel can be defined having a reference viscosity of about 100 centipoise or more at a shear rate of 100 / sec.
- the initial pH of a borate crosslinked fracturing fluid must be in a range greater than 8.5 to 9.5.
- the elevation of the fracture fluid pH to a level in excess of 9.5 poses some operational problems.
- return water, production water, sea water, fresh water or mixtures thereof contain multivalent ions such as calcium and magnesium ions, which form insoluble precipitates at a pH greater than a range of 9.5 to 10.0, if chelating agents or sequestrants that inhibit multivalent ions are not used.
- the presence of solid precipitates reduces the effective conductivity of the support agent within the fracture, and ultimately affects the productivity of the fracturing operation.
- Figure 1 represents the results of tests carried out to verify the reoiological behavior with a crosslinked gel.
- the present invention provides crosslinked fracturing fluids and methods of using fluids to fracture underground formations that meet the needs described above and overcome the deficiencies of the prior art.
- Fracturing fluids and inventive methods are particularly useful for use in oil and gas fields where the management of return and production water has involved different complications such as those in which there are no injector wells or in which it exceeded the flow of water production above the injection rates.
