... A parametric simulation study showed that the quantity of gas injected in an injection period was relatively insensitive to the oil phase diffusion coefficients but was sensitive to solvent solubility in oil, dissolution rates, gas phase diffusion coefficients, molar densities in the oil phase, gas phase...

... for heavy oil/bitumen recovery may involve the use of hydrocarbon (n- alkane) solvent at relatively high solvent/oil ratios. Previous work at ARC has shown that at high solvent loadings, the oil/solvent mixture partitions into a solvent-rich oil phase and a heavy-ends-rich (mostly asphaltene) oil phase...

... is assumed to be laterally infinite. This theory, referred to by Butler as LinDrain Theory in his writings, is generalized here to the case when dissolved gas is present. The dissolved gas is taken to be methane and it is assumed that methane is soluble in the oil phase but not in the water phase. Dead...

... in an improved oil production rate. All components of naphtha travelled freely in the vapour chamber and accumulated along the vapour chamber front in both the vapour and oil phases. At higher solvent to steam ratios oil production rate decreased due to an accumulation of solvent gas at the vapour chamber front...

... is modelled as a pure solid that may flow as a suspension in the oil phase or deposit onto the rock surface. It is shown that this model is capable of modelling the important mechanisms of asphaltene precipitation in the Vapex process. The growth of the solvent chamber is governed by molecular diffusion...
