Sand-consolidation resins--their stability in hot brine
Four commercial in-situ sand-consolidation resin systems and one resin-sandpack system were tested for durability in hot (160/sup 0/F (71.1/sup 0/C)) flowing brine for up to 28 months, and in as much as 30 million PV brine. Brine was selected as the test fluid since it is considered to be more damaging than oil to the stability of resin consolidated sand. Two epoxy and two furan systems were investigated. Other commercial consolidation techniques-e.g., involving phenol formaldehyde and phenolic furan resins described in the literature-have been recognized as effective sand-stabilization products; however, some limitations had to be placed on the scope of the study because of equipment and time limitations. Perhaps these techniques will be the subject of future investigations. Note that all processes evaluated in this investigation used silane coupling agents contained in the resinous materials. These agents increase the stability of sands consolidated by organic polymers. The overflush-catalyzed furan resin (System A) and the internally catalyzed epoxy resin (System D) demonstrated greater stability under the specific test conditions employed. System A retained higher strength during the first 15 million PV. Thereafter, System D appeared to be better. System A exhibited the highest initial permeability, and, after 5 million PV, Systems A, B, and D were about equal in permeability. From that point, the permeability of System A slowly increased, while decreasing for Systems B and D. The epoxy-resin sandpack (40- to 60-mesh sand) showed little change in compressive strength after exposure to more than 30 million PV of hot, flowing brine.
