Abstract
Disclosed herein are compositions and methods for increasing the viscosity of a calcium-containing fluid by addition of a modifying agent. The resulting enhanced viscosity fluid may be used in a variety of applications including drilling, to create an enhanced-viscosity fluid, and demolition/mining to create an expansive putty for use in underwater and overhead applications.
Claims9
A method of at least partially sealing a leak in a tubing string of a well comprising:
- mixing a curable phenolic resin, comprising phenol and formaldehyde in a molar ratio of about 10:1, with water to create a resin+water mixture having a resin:water ratio of 1:1 to 1:4;
- adding the mixture containing the curable phenolic resin to the backside of a tubing string;
- pumping slowly the mixture containing the curable phenolic resin down a backside of the tubing string and up through the tubing string to allow the curable phenolic resin to enter the leak from the tubing string and into the backside of the tubing string;
- allowing the curable phenolic resin to cure;
- and thereby
- sealing the leak, wherein of the leak's position in the tubing string is unknown.

A method of at least partially sealing a leak in a well comprising:
- creating a mixture comprising water and an uncured resin, wherein the resin is a phenolic resin comprising phenol and formaldehyde, in a molar ratio of phenol to formaldehyde of about 10:1, and wherein resin to water ratio is from 1:1 to 1:4;
- adding the mixture to a backside of a tubing string;
- pumping the mixture down the backside of the tubing string and up through the tubing string and through the leak into the backside of the tubing string;
- allowing the phenolic resin to cure;
- and thereby
- sealing the leak, wherein the position of the leak in the well is unknown.
