... to the calculated permeability from logging data. The Core Measurement System (CSM) has the same disadvantage. Since core samples have high level of heterogeneity, either an average permeability can be calculated or certain points should be chosen along the core sample(2l. The rock heterogeneity is a good reason...

... of tracer tailing. Tailed breakthrough curves are known from displacement in cores with local heterogeneity. Good agreement has been obtained between the experimental results and the semiphenomenological model of Coats Smith. Thus~ the mechanism involved in this anomalous dispersion is not trapping...

... laboratories at NOVA Husky Research. This analysis gives a detailed picture of the various heterogeneities within each core section including cracks, shale barriers and clay clasts, and also allows determination of core properties such as bulk density and porosity. Bulk densities determined from the CAT scan...

... helped in refining reservoir description in terms of lateral as well as vertical heterogeneities. These additional details were independently verified by a history match of the unit's performance and, were by and large consistent with the cross-section fence diagrams of the pay zone prepared from log...

... Abstract Heavy oil reservoirs of Saskatchewan are characterized by thin pay, shaley sand, heterogeneity, low productivity and bottom water. Thermal recovery processes are not expected to be economically feasible for reservoirs containing approximately eighty percent of the heavy all...
