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.
Claims16
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, wherein the one or more reactive components are configured to initiate one or more chemical reactions that cause the carrier fluid to expand;
- determining, via a control system based on measurement data indicative of a volume of the one or more reactive components delivered to the wellbore, 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, delivery of the one or more reactive components to the wellbore in response to determining that the threshold volume is met or exceeded;
- and
- generating electricity in the wellbore using piezoelectric fibers, wherein the electricity is configured to cause the one or more reactive components to initiate the one or more chemical reactions.
A method for initiating chemical reactions in a wellbore, the method comprising:
- reducing a particle size of one or more reactive components via a mechanical tool, wherein the one or more reactive components are configured to initiate one or more chemical reactions in the wellbore, and wherein reducing the particle size of the one or more reactive components increases a reactivity of the one or more reactive components by increasing a surface area of the one or more reactive components;
- delivering the one or more reactive components having the reduced particle size to the wellbore via a carrier fluid, wherein the one or more chemical reactions cause the carrier fluid to expand;
- carrying out the one or more chemical reactions via contact between the one or more reactive components in the wellbore;
- determining, via a control system based on measurement data indicative of a volume of the one or more reactive components delivered to the wellbore, that the volume of the one or more reactive components meets or exceeds a threshold volume of the one or more reactive components;
- and
- terminating, via the control system in response to determining that the threshold volume is met or exceeded, at least one of delivery of the one or more reactive components to the wellbore or reduction of the particle size of the one or more reactive components.

- and
- terminating, via the control system in response to determining that the threshold volume is met or exceeded, at least one of delivery of the one or more reactive components to the wellbore or reduction of the particle size of the one or more reactive components.
