Question
A study in an oil field has been conducted to enable analytical estimation of the porosity of a reservoir from measured
permeability values. A sample of true measurements of both parameters at the same locations is recorded in the table
below. A linear regression model for the two parameters using least square estimates method has been developed. Using
the linear regression model, determine the residual in estimating the porosity when the permeability is equal to 70 uD.
