“…This was a major improvement compared to Hughes (1995) experiments, since he was using the patient table whose accuracy is f 1 mm. The field of view used for this experiment was 24 cm, the image matrix, resolution, voltage, amperage, filter used, and more scanner settings are shown in Table 3.1.…”

“…For this work, we used two of the three rectanguIa.r blocks of Boise sandstone cores constructed and used by Hughes (1995). Both core holders consist of two 2 15/16x 9 1 % x 11 inch blocks.…”

“…Due to the rectangulm shape and the desire to measure in-situ saturations through the use of the CT scanner, special core holders must be used (Hughes, 1995). Epoxy is an X-ray transparent material and core holders of this material are recommended by Castanier place with automotive gasket material (Permatex Ultra Blue RTV Silicon Gasket) was also used.…”

“…This positionhg system was one of the major improvements to previous designs (Guzman, 1993;Hughes, 1995), because in this way, we can obtain cross sectional @ages of the core at the same locations at any desired time of the experiment. This could not be performed in other studies because the standard patient table of any CT Scanner of this type lacks comparable accuracy.…”

“…This part of the experiment gave us resuks that can be compared with the ones obtained by Hughes (1995), and eventually used to evaluate how well the new experiment worked. after oil injection started.…”
