Rapidly cooling a geologic formation in which a wellbore is formed
First Claim
1. A wellbore tool comprising:
- a first chamber configured to be positioned within a wellbore, the first chamber comprising a cooling fluid;
a second chamber positioned uphole of the first chamber, the first chamber and the second chamber configured to be lowered to a position within the wellbore, the second chamber comprising a cold source at a sub-zero temperature, the cooling fluid configured to be cooled upon contacting the cold source;
a separation member positioned between the first chamber and second chamber, the separation member separating the cooling fluid and the cold source; and
an activation device connected to the separation member, the activation device configured to cause the separation member to allow the cold source to contact the cooling fluid.

Abstract
A first chamber is configured to be positioned within a wellbore. The first chamber includes a cooling fluid. A second chamber is positioned uphole of the first chamber. The first chamber and the second chamber are configured to be lowered to a position within the wellbore. The second chamber includes a cold source at a sub-zero temperature. The cooling fluid is configured to be cooled upon contacting the cold source. A separation member is positioned between the first chamber and second chamber. The separation member separates the cooling fluid and the cold source. An activation device is connected to the separation member. The activation device is configured to cause the separation member to allow the cold source to contact the cooling fluid.
