Abstract
A method of servicing a wellbore penetrating at least a portion of a subterranean formation, including placing into the wellbore a wellbore servicing fluid including a friction reducer, an iron control agent, and an aqueous fluid. The iron control agent can include a compound according to Structure I, a salt of Structure I, or combinations thereof: wherein R1, R1a, R2, R2a, R3 and R3a are defined as set forth in the specification. The methods in this disclosure can be used for iron mitigation.

A method of servicing a wellbore penetrating at least a portion of a subterranean formation, comprising:
- placing a wellbore servicing fluid into a wellbore, wherein the wellbore servicing fluid comprises a friction reducer, an iron control agent, and an aqueous fluid, wherein the iron control agent comprises a compound according to Structure I, a salt of Structure I, or combinations thereof:
- Structure I:
- wherein R1, R1a, R2, R2a, R3 and R3a are independently selected from a group consisting of H, —OH, halo, straight or branched (C1-C6)alkyl, straight or branched (C2-C6)alkenyl, straight or branched (C2-C6)alkynyl, (C3-C14)aryl, (C3-C14)-cycloalkyl, (C3-C14)aryl(C1-C6)alkylene-, (C3-C14)heteroaryl-(C1-C6)alkylene-, (C3-C14)heteroaryl, (C3-C14)heterocycloalkyl, (C3-C14)heterocycloalkyl-(C1-C6)alkylene-, (C3-C14)heteroaryl-(C3-C6)heterocycloalkylene-, (C3-C14)aryl-(C3-C14)heterocycloalkylene-, (C3-C14)-aryl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-, (C3-C14)heteroaryl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-, (C3-C14)heterocycloalkyl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-.
A method of servicing a wellbore penetrating at least a portion of a subterranean formation, comprising:
- placing a solid-free fracturing fluid into the wellbore at an injection rate for generating a treating pressure above a fracture gradient to create one or more fractures in the subterranean formation, wherein the solid-free fracturing fluid comprises a friction reducer, an iron control agent, and an aqueous fluid,
- wherein the iron control agent comprises a compound according to Structure I, a salt of Structure I, or combinations thereof:
- Structure I:
- wherein R1, R1a, R2, R2a, R3 and R3a are independently selected from a group consisting of H, —OH, halo, straight or branched (C1-C6)alkyl, straight or branched (C2-C6)alkenyl, straight or branched (C2-C6)alkynyl, (C3-C14)aryl, (C3-C14)-cycloalkyl, (C3-C14)aryl(C1-C6)alkylene-, (C3-C14)heteroaryl-(C1-C6)alkylene-, (C3-C14)heteroaryl, (C3-C14)heterocycloalkyl, (C3-C14)heterocycloalkyl-(C1-C6)alkylene-, (C3-C14)heteroaryl-(C3-C6)heterocycloalkylene-, (C3-C14)aryl-(C3-C14)heterocycloalkylene-, (C3-C14)-aryl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-, (C3-C14)heteroaryl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-, (C3-C14)heterocycloalkyl-(C1-C6)alkyl-(C3-C14)heterocycloalkylene-;
- and
- placing a mixture of the solid-free fracturing fluid and proppants into the wellbore to place at least one proppant into the one or more fractures.
