Patented Casing and Tubing Leak Repair Resin
Using a modified E2 product coupled with the exclusively designed E-Lock, a blend of oxidizing additive and water is pumped down into the leak at a low rate to deposit the repair material inside the leak.
Next, the E-Lock is pumped down and immediately solidifies when it comes into contact with the oxidizers.
In cases where fluid cannot be moved through a leak at consistent rates, the leak can be isolated by plug or packer and then a diluted blend of E-Lock can be spotted across the interval. Once the E-Lock is across the leak, the packer is set and pressure is applied to the tubing, forcing the liquid BN-Lock through the leak.
Due the typical small size of such a leak, oxidizing catalyst is not necessary in order to achieve required strength.
Advantages over competing solutions:
E-Lock is water soluble, and therefore does not require solvents or other hazardous fluids to be used in cleanup after the job.
The viscosity of E-Lock can be decreased by dilution with water, allowing deployment/penetration through much smaller holes, cracks or thread leaks than existing technologies.
