1. 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.
