  This paper demonstrates Semivariogram modelling of physical properties (porosity and Permeability) and its procedure for Ikphesi dolomitic marble deposit Akoko Edo L.G.A, Edo State, Nigeria. Forty two (42) dolomite samples were collected at pre- determined distance (6m interval depending on the pit size and horizontal level). Porosity and permeability values for the test samples were determined from the laboratory using ASTM Standard Test Method C97-83, and ASTM Standard Test Method D 4525-90. Semivariogram values for different distances covered and number of pairs were determined using Microsoft Excel package. Experimental semivariogram plots for both permeability and porosity values were done in East-West and North- South directions to determine the semivariogram properties (sill, nugget effect, and range). Final modelling for porosity and permeability of the data set (values) were .. Read More»
