PROBLEM # 1 Use the inverse distance method (IDW) to estimate the porosity at the unknown location (8,5). Point Location (x,y) (3,4) (4,1) (9,10) (8,5) Porosity (%) 20 18 7 ?? PROBLEM # 2 Use the same data from problem # 1 to estimate the porosity at the unknown location and the standard error using the ordinary kriging method. The semi-variogram values in any direction can be estimated using the following equation: Y(h) = 100 1– -3h exp () 100 Sill = 100 PROBLEM # 3 Use the same data from problem # 1 & 2 to estimate the porosity at the unknown location and the standard error using the simple kriging method. Assume the global mean = 15%. %3D
