Evaluation of Clay and Drilling Fluid Quality

The present work is concerned with the construction of a nomogram, which can be used to evaluate the quality of clay materials. Evaluation is carried out according to three parameters: colloidality coefficient, fractional volume of active solid, and mud viscosity. The constructed nomogram is also used to evaluate the quality of drilling fluid with respect to solid content, follow the process of increasing mud density to be sure the solid content is optimum. Design and drawing the proposed nomogram is carried out by using programming language “C++”.
