Abstract

Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.

First claim

The invention claimed is:

1. A method for initiating chemical reactions in a wellbore, the method comprising:
delivering one or more reactive components via a carrier fluid to the wellbore, the one or more reactive components being configured to initiate one or more chemical reactions that cause the carrier fluid to expand, wherein the delivery of the one or more reactive components to the wellbore is controlled via a control system;
providing measurements to the control system, the measurements including data indicative of a volume of the one or more reactive components delivered to the wellbore;
determining, via the control system, that the volume of the one or more reactive components delivered to the wellbore meets or exceeds a threshold volume of the one or more reactive components;
terminating, via the control system, the delivery of the one or more reactive components to the wellbore in response to determining that the threshold volume is met or exceeded; and
introducing heat or electromagnetic radiation to the wellbore via one or more fiber optic cables, wherein the heat or the electromagnetic radiation is configured to cause the one or more reactive components to initiate the one or more chemical reactions.

2. The method of claim 1 , wherein the one or more fiber optic cables are configured to deliver laser, infrared, microwaves, or other forms of electromagnetic radiation to the one or more reactive components.

3. The method of claim 1 , comprising controlling, via the control system, a quantity of the heat or the electromagnetic radiation introduced to the wellbore, a duration at which the heat or the electromagnetic radiation is introduced to the wellbore, a frequency at which the heat or the electromagnetic radiation is introduced to the wellbore, an area within the wellbore at which the heat or the electromagnetic radiation is introduced, or a combination thereof.

4. The method of claim 1 , wherein the one or more reactive components are embedded within cement within the wellbore.

5. The method of claim 1 , wherein the threshold volume of the one or more reactive components corresponds to a predefined extent of the one or more chemical reactions.
