Dual functioning corrosion inhibitor and foaming agent
A method may include: placing into a wellbore penetrating a subterranean formation a foaming agent, wherein the wellbore comprises a produced fluid from the subterranean formation; and foaming the produced fluid. The foaming agent may include at least one of the following structures: wherein R1 and R2 are individually selected from an alkyl group, an alkenyl group, a heteroatom substituted alkyl group, or a heteroatom substituted alkenyl group, wherein R1 comprises 5 carbon atoms to 22 carbon atoms in length, and wherein R2 comprises 1 carbon atom to 8 carbon atoms.
1. A method comprising:
introducing a foaming agent into a wellbore; and
foaming a fluid present in the wellbore,
wherein the foaming agent is at least one of the following structures:
wherein R1 and R2 are individually selected from an alkyl group, an alkenyl group, a heteroatom substituted alkyl group, or a heteroatom substituted alkenyl group, wherein R1 comprises 5 carbon atoms to 22 carbon atoms in length, and wherein R2 comprises 1 carbon atom to 8 carbon atoms.
2. The method of claim 1 wherein foaming agent is introduced into the wellbore via an annulus drip, a slip stream, a capillary string, production line, or a combination thereof.
3. The method of claim 1 wherein the foaming agent has a corrosion inhibition property and slows corrosion on at least one surface of equipment disposed within the wellbore.
4. The method of claim 1 wherein the foaming agent is introduced into the wellbore during an artificial lift operation.
5. The method of claim 1 wherein the foaming agent is protonated by an acid before or during the step of introducing to form a protonated foaming agent.
6. A method comprising:
placing into a wellbore penetrating a subterranean formation a foaming agent, wherein the wellbore comprises a produced fluid from the subterranean formation, and wherein the foaming agent comprises the following structure:
wherein R1 and R2 are individually selected from an alkyl group, an alkenyl group, a heteroatom substituted alkyl group, or a heteroatom substituted alkenyl group, wherein R1 comprises 5 carbon atoms to 22 carbon atoms in length, and wherein R2 comprises 1 carbon atom to 8 carbon atoms; and
foaming the produced fluid.
7. The method of claim 6 wherein foaming agent is present in a treatment fluid, the treatment fluid comprising the foaming agent and a carrier fluid.
8. The method of claim 7 wherein the carrier fluid is selected from the group consisting of water, a liquid hydrocarbon, an alcohol, and combinations thereof.
9. The method of claim 6 further comprising placing a foaming gas in the wellbore.
10. The method of claim 6 wherein the foaming agent is placed in the wellbore through a production line disposed within the wellbore.
11. A method comprising:
introducing a treatment fluid into a wellbore, the treatment fluid comprises: a foaming agent and a carrier fluid comprising a C3-C10 alcohol, wherein the foaming agent is present in an amount of about 20% to about 60% by weight of the treatment fluid, wherein the foaming agent is:
and
wherein R1 and R2 are individually selected from an alkyl group, an alkenyl group, a heteroatom substituted alkyl group, or a heteroatom substituted alkenyl group, wherein R1 is 5 carbon atoms to 22 carbon atoms in length, and wherein R2 is 1 carbon atom to 8 carbon atoms; and
foaming a fluid in the wellbore.
12. The method of claim 11 wherein foaming agent is introduced into the wellbore via a production line.
13. The method of claim 11 further comprising protonating the foaming agent with an acid before or during the step of introducing to form a protonated foaming agent.
