.... In principle, this phenomenon can also occur in carbonate reservoirs. Fine carbonate particles generated from the drilling can mix into the mud and invade into the formation when there are favorable porosity and permeability conditions. A theoretical model has been developed to calculate the original formation...

... the time that the activated water passes a detector. Theoretical models and laboratory experiments have demonstrated that the simple v=d/t relationship is unsatisfactory at low and high velocities. Algorithms to correct the measured velocity have been developed from the theoretical models and laboratory...

...-porosity systems is presented. The starting point of the mathematical development is a theoretical model proposed by Maxwell, and consisting of a set of equal spheres dispersed within a conducting medium. By making use of some previous ideas suggested by P6rez Resales, one arrives at an expression...

... in Wyoming illustrates the potential usefulness of hole-to-hole measurements in helping to reduce the number of drill holes needed to delineate a uranium ore body. This study also shows the importance of using conventional well logs and theoretical models to interpret data from widely spaced electrodes...
