To achieve that, the drilling mud system needs continuous and direct supervision such asmeasuring its rheological properties and treating any deviation in their values. Viscosity is themost important property in hydraulic program success due to its direct relation with bottom holecleaning during drilling, thus related with the drilling rate, so this property should be keptbasically to ensure bottom hole cleaning and high drilling rate at the same time.Some chemicals such as thinner should be added to the mud system to keep both viscosity andother properties within certain standards and required limits; these materials have a high cost,increasing both the metric cost and the final cost of such well.The aim of this research is to test the physical and chemical properties for a local material, as ...

The main aim of this work is to study the effect of the gypsum mud compositions on their rheological behavior under the conditions of high-pressure and high temperature. Eleven samples of gypsum mud were tested using Fann viscometer model 50-C. All the tested samples had the same trend of reduction in both plastic viscosity and yield point with increasing temperature. The results showed that with 5 ppb of Q Broxine thermal degradation is obtained at approximately 150 0 F; this is due to the over treatment with thinner which result in more soluble solids and higher rheological properties while the decrement in NaOH concentration from 0.7 ppb to 0.35 ppb results in an increase in both yield point and plastic viscosity; this is due to the loss of OH-1 ions. Six rheological models were adopted: Bingham, power law, modi...
