... and dried. These processes were very time consuming and difficult because of the tight rock matrix. A Ruska Gas Permeameter was used for a gas expansion experiment to measure the porosity and permeability variation at different overburden pressures. In the laboratory tests, indicative different core plugs...

.... In both those cases, recovery was lower than the steam-only case. The other SAGD experiments were carried out using limestone core plugs saturated with the same heavy oil. Similar trends were observed for core plug experiments; however, the recovery was better when n-butane was added to steam...

... of 3rd generation Philips Tomoscan 60/TX. The schematic of CT is presented in Figure 1. The same core plug taken from a full size core from the field was used during the experiments. The diameter and length of the core plug were 6.46 cm and 3.81 cm, respectively. The core has porosity of 18.4...
