Abstract
Abstract Emulsion compositions containing substantial amounts of gilsonite consist essentially of a gilsonite phase consisting of a mixture of between about 33 and about 95% gilsonite, and a petroleum hydrocarbon having a boiling point above about 200° F., and a water phase consisting essentially of water and a small amount of emulsifying agent. The emulsifying agent may include a surface active clay.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
An emulsion composition consisting essentially of (a) a gilsonite phase consisting of a mixture of between about 33 and about 95% gilsonite, and a petroleum hydrocarbon having a boiling point above about 200° F., and (b) a water phase consisting essentially of water and between about 0.05 and about 10% of an emulsifying agent, and wherein the gilsonite:water phase ratio is between about 1:2 and 3:1, respectively.
Claim 2
Dependent Claim
67 words
An emulsion composition consisting essentially of (a) a gilsonite phase consisting of a mixture of between about 33 and about 95% gilsonite, and a petroleum hydrocarbon having a boiling point above about 200° F., and (b) a water phase consisting essentially of water and between about 0.05 and about 10% of an emulsifying agent, and wherein the gilsonite:water phase ratio is between about 1:2 and 3:1, respectively.
Claim 3
Dependent Claim
23 words
