A method of treating fluids in an annulus, comprising the steps of: providing a fluid-circulation annulus between a host tubular and a liner therein; and manipulating fluids in the annulus so that the relative proportions of fluid components in the annular fluid correspond to the relative permeation rates of the fluid components from the bore to the annulus. A functional relationship between the spatial frequency and the phase is analyzed for the spatial frequencies. As the clustering screen is applied, the threshold values in the clustering screen are reduced by the real number constants thereby modulating the effect of the application of the clustering screen. The system allows various communication devices to access public and private data bases on the existing communication infrastructure, including communication devices such as e-mail-enabled cell phones, PDA’s, PC’s, pages, etc.
