For oil, the new relationship with the following formula represents a 307.0 +26552.0 a 34540.0 (, S) (3) For gas, the penetration rate is usually assumed to be about oil under similar conditions forecast permeability values of l0 (Silun Bei Xie company, 1987 ~ Hilchie, 1982),abercrombie fitch paris (http://www.abercrombiefitchparis.com), this equation is K = 30.7 +2655 j52-3454 (≠,ed hardy paris (http://www.edhardyparis.net), S). '(4) mapping methods help to visualize the accuracy of a relationship. Therefore, Figure 4 shows the permeability relationship (equation (3)) predicted and measured values of the intersection graph. The relationship used in this study most of the plotted points fall very close to the ideal relationship 45. Near the line.

Brief description of the amount of board to use, it must be assumed, for a particular reservoir, by logging data to obtain porosity and irreducible water saturation values. The steps to use the amount of board is to start reading on the horizontal ruler given porosity value, and then move straight up until that point and the known water saturation values from the tag-line intersection point moves horizontally to the left meet with the ruler until the penetration rate, then the predicted permeability values can be read out. Comparison of relationship used to determine the relative accuracy of the statistical relationship are listed in Table 3. Present-day reservoir relationship (equation (3) and (5)) and all existing relationships with the field data type have been tested. Table 4 gives the results, it seems Tixier, Timur, Coates and Coates-Dumanoir companies such relationship predicted permeability values are underestimated. Relationship obtained in this study is the best, it is because it's the average percentage deviation (APD), the mean absolute percentage deviation (AAPD) and the standard deviation (sD) the lowest. * Sic ■ Volume 8, No. 5 Eastern Niger Delta sparse orange sandstone permeability empirical formula 0.100.200.300.4005050O ● 003000. fi0 camp 0.7O200.
