ABSTRACT:
A method for determining at wellsites the solids content of drilling fluids by high-frequency dielectric measurements including: preparing samples of the drilling fluid, of the drill cuttings from the formation, and of each solids-additives type added to the drilling fluid for uniform dielectric constant measurements at preselected frequencies and obtaining the solids content in accordance with the relationship between the dielectric constant measurements of the drilling fluid-solids, drill cuttings, and each of the solids-additives type. In accordance with the method of the invention two levels of determination are possible. These levels of determination depend upon whether the quantities of solids-additives type added to the drilling fluid are known.
