Abstract
Abstract A consolidating composition and a method is provided for placing a consolidated mass of particles in a borehole having high compressive strengths and being permeable to the flow of fluids. The consolidating composition comprises a mixture produced by sequentially mixing together, (1) particulate solids and a carrier liquid and (2) an uncured aldehyde-hydroxylaryl resin dissolved in a solvent which itself is soluble in said carrier liquid. Alternatively the resin solution and particulate material can be simultaneously mixed into the carrier, e.g., the resin and particles are premixed and then introduced into a carrier liquid.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
21 words
The method of claim 1 wherein the volume ratio of resin to particulate solids ranges from about 1:20 to about 4:1.
Claim 2
Dependent Claim
21 words
The method of claim 1 wherein the volume ratio of resin to particulate solids ranges from about 1:2 to about 1:20.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the solvent comprises at least one of an aliphatic mono-alcohol containing from four to eight carbon atoms.
Claim 4
Dependent Claim
43 words
The method of claim 1 including in addition mixing with the resin solution an additional liquid solvent for said resin characterized as being substantially insoluble in said hydrocarbon carrier liquid in an amount of 1 percent or less by weight of said mixture.
Claim 5
Dependent Claim
27 words
The method of claim 5 wherein the insoluble solvent is present in an amount ranging from about 0.4 to about 0.6 percent by weight of said mixture.
Claim 6
Dependent Claim
26 words
The method as defined in claim 1 including contacting the emplaced mass of particles with a catalyst which accelerates the curing of the hydroxyaryl aldehyde resin.
Claim 7
Dependent Claim
32 words
The method of claim 1 including mixing in addition into said carrier liquid an effective amount of a coupling agent to enhance the bond between the set resin and the particulate solids.
Claim 8
Dependent Claim
12 words
The method of claim 8 wherein said coupling agent is a silane.
Claim 9
Dependent Claim
46 words
The method of claim 1 wherein said solvent is at least one of an aliphatic mono-alcohol containing from four to eight carbon atoms, including in addition mixing with said resin solution an additional solvent for said resin said additional solvent being insoluble in said carrier liquid.
