Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
THE METHOD OF GELLING A HYDROCARBON LIQUID CONFINED IN A PASSAGEWAY, TO RENDER THE HYDROCARBON NONFLOWABLE AND TO IMPART TO IT THE CAPACITY OF BLOCKING AND PLUGGING THE FLOW OF LIQUID THROUGH THE PASSAGEWAY, CONSISTING ESSENTIALLY OF INTERMIXING WITH THE HYDROCARBON IN THE PASSAGEWAY ABIETYL AMINE AND CARBON DISULFIDE IN AN AMOUNT OF EACH SUFFICIENT TO PROVIDE AT LEAST 1 PART BY VOLUME OF ABIETYL AMINE AND AT LEAST 0.75 PARTS BY VOLUME OF CARBON DISULFIDE AT A TEMPERATURE BETWEEN ABOUT 0*F. AND 115*F.
Claim 2
Independent Claim

AND 115*F.
Claim 3
Independent Claim
78 words
THE METHOD OF EFFECTING GELATION IN AN OIL-BASE WELLTREATING FLUID TO CONTROL THE FLUID LOSS THEREFROM INTO A POROUS FORMATION DURING TREATMENT CONSISTING ESSENTIALLY OF INJECTING INTO SAID WELL-TREATING LIQUID AT LEAST ABOUT 1 PART BY VOLUME OF ABIETYL AMINE AND AT LEAST ABOUT 0.75 PART BY VOLUME OF CARBON DISULFIDE TO EFFECT GELATION OF AT LEAST A PORTION OF SAID WELL-TREATING FLUID IN THE FORMATION AND THEREBY INHIBITING LOSS OF THE WELLTREATING FLUID INTO THE POROUS FORMATION.
