Particulate resin-coated composition

Claim 1

THE METHOD OF MAKING A RESIN-COATED PARTICULATE COMPOSITION OF DISCRETE PARTICLES HAVING A FILM OF OIL ON THE RESIN-COATED PARTICLES OF SAID COMPOSITION FOR SUBSEQUENT ADMIXING WITH OIL TO MAKE A PUMPABLE WELLTREATING OIL SLURRY WHICH SETS IN SITU TO A UNITARY MASS WHEN SUBJECTED TO THE THERMOSETTING TEMPERATURE OF SAID RESIN COMPRISING THE STEPS OF: HEATING, AT A TEMPERATURE BETWEEN 120* AND 250*F., A PARTIALLY CONDENSED STAGE B TYPE RESIN WHICH IS THERMOSETTING WHEN SUBJECTED TO A SUFFICIENTLY HIGH TEMPERATURE BUT WHICH IS THERMOPLASTIC AND CAPABLE OF BEING REPEATEDLY SOFTENED AND HARDENED WHEN SUBJECTED ONLY TO A TEMPERATURE BELOW THE THERMOSETTING TEMPERATURE, UNTIL SAID RESIN HAS A VISCOSITY OF BETWEEN 30 AND 40 CENTIPOISES MEASURED AT 200*F., ADMIXING WITH SAID RESIN, WHILE MAINTAINING IT AT SAID TEMPERATURE, A PARTICULATE MATERIAL INERT TO SAID RESIN TO RESIN-COAT SAID PARTICLES AND HAVING A PARTICLE SIZE SUCH THAT SUBSTANTIALLY ALL PASSES THROUGH A NO. 10 MESH SIEVE BUT IS RETAINED ON A NO. 100 MESH SIEVE, SLURRYING SAID MIXTURE WITH SUFFICIENT OIL TO OIL-WET THE PARTICLES OF SAID MIXTURE WHILE MAINTAINING SAID TEMPERATURE UNTIL SAID RESIN FORMS A DRY HARD COATING ON THE PARTICLES UPON BEING COOLED TO ROOM TEMPERATURE, AND REMOVING SUBSTANTIALLY ALL THE OIL FROM THE RESIN-COATED PARTICLES IN EXCESS OF THAT ADHERING TO AND FORMING AN OIL FILM OVER SAID DISCRETE PARTICLES.

Claim 2

THE METHOD OF MAKING A RESIN-COATED PARTICULATE COMPOSITION OF DISCRETE PARTICLES HAVING A FILM OF OIL ON THE RESIN-COATED PARTICLES OF SAID COMPOSITION FOR SUBSEQUENT ADMIXING WITH OIL TO MAKE A PUMPABLE WELLTREATING OIL SLURRY WHICH SETS IN SITU TO A UNITARY MASS WHEN SUBJECTED TO THE THERMOSETTING TEMPERATURE OF SAID RESIN COMPRISING THE STEPS OF: HEATING, AT A TEMPERATURE BETWEEN 120* AND 250*F., A PARTIALLY CONDENSED STAGE B TYPE RESIN WHICH IS THERMOSETTING WHEN SUBJECTED TO A SUFFICIENTLY HIGH TEMPERATURE BUT WHICH IS THERMOPLASTIC AND CAPABLE OF BEING REPEATEDLY SOFTENED AND HARDENED WHEN SUBJECTED ONLY TO A TEMPERATURE BELOW THE THERMOSETTING TEMPERATURE, UNTIL SAID RESIN HAS A VISCOSITY OF BETWEEN 30 AND 40 CENTIPOISES MEASURED AT 200*F., ADMIXING WITH SAID RESIN, WHILE MAINTAINING IT AT SAID TEMPERATURE, A PARTICULATE MATERIAL INERT TO SAID RESIN TO RESIN-COAT SAID PARTICLES AND HAVING A PARTICLE SIZE SUCH THAT SUBSTANTIALLY ALL PASSES THROUGH A NO. 10 MESH SIEVE BUT IS RETAINED ON A NO. 100 MESH SIEVE, SLURRYING SAID MIXTURE WITH SUFFICIENT OIL TO OIL-WET THE PARTICLES OF SAID MIXTURE WHILE MAINTAINING SAID TEMPERATURE UNTIL SAID RESIN FORMS A DRY HARD COATING ON THE PARTICLES UPON BEING COOLED TO ROOM TEMPERATURE, AND REMOVING SUBSTANTIALLY ALL THE OIL FROM THE RESIN-COATED PARTICLES IN EXCESS OF THAT ADHERING TO AND FORMING AN OIL FILM OVER SAID DISCRETE PARTICLES.
