... pure chemicals including kerosene, toluene, xylene, naphtha, and heptane to reduce heavy oil viscosity, and hence reduce the oil production and transportation problems and costs. The research also develops four cost effective chemical formulations based on organic-hydrocarbon soluble based chemicals...

... the viscous oil samples with viscosities of 1146 cP and 4043 cP, respectively. The densities of oil samples were in the range of 0.8688 to 1.0968 g/cm 3 at room temperature of 20ºC. Alkane solvents used in the tests, i.e., pentane, heptane, and decane, were purchased from Fisher Scientific, with stated...

... Abstract This paper presents an extensive analysis solvent injection at elevated temperatures to recover heavy- oil/bitumen from fractured carbonates. Three different solvents (propane, heptane and distillate oil - naphtha) were injected at different temperatures representing a wide range...

... introduced into the system and heavy-oil recovery. We conducted a series of dynamic experiments in which liquid (heptane) solvent was injected into a heavy oil saturated rock matrix, surrounded by a fracture with and without pre-thermal injection. Water-wet rock matrix (sandstones) was saturated with heavy...
