Abstract
An epoxy resin composition curable to a hard impermeable solid which contains a liquid aromatic diluent having the general formula: C.sub.6 (R.sub.1).sub.6 wherein R.sub.1 is hydrogen; a straight or branched chain alkyl radical; a cycloparaffin radical or a mixture thereof; wherein the alkyl and cycloparaffin radicals have within the range of about 1 to 10 carbon atoms; and further wherein at least one R.sub.1 group is said alkyl or cycloparaffin radical.
Claims13
An epoxy resin composition for sealing a subterranean zone penetrated by a well bore containing about 20-40 parts by volume of an aromatic diluent selected to provide a pumpable epoxy resin composition wherein said aromatic diluent is selected to prevent premature setting by absorbing heat and to provide a cured epoxy resin composition occupying substantially the same volume as said pumpable epoxy resin;
- wherein said pumpable epoxy resin composition is curable to a high strength, impermeable matrix with a weight loss of less than about 20 parts per 100 parts by weight of said pumpable epoxy resin composition;
- said pumpable epoxy resin composition comprising an epoxy resin, a curing agent and said selected aromatic diluent;
- wherein said selected aromatic diluent is at least one or a mixture contaning an aromatic hydrocarbon of the general formual C.sub.6 (R.sub.1).sub.6 wherein R.sub.1 is hydrogen, a straight or branched chain alkyl radical, a cycloparaffin radical or a mixture thereof;
- wherein each alkyl and cycloparaffin radical has about 1-10 carbon atoms;
- and further wherein at least one R.sub.1 group is radical.
In a composition for sealing a subterranean zone penetrated by a well bore comprising a pumpable epoxy resin composition, the improvement of including in said pumpable epoxy resin composition an aromatic diluent selected to produce cure to an epoxy resin composition having a high strength, impermeable matrix occupying substantially the same volume as said pumpable epoxy resin composition, with a weight loss of less than about 20 parts per 100 parts by weight of said pumpable epoxy resin composition, thereby sealing said zone.
