An operator wanted to reduce its drilling costs and environmental impact through more precise monitoring of mud properties. A RheoProfiler automated rheometer was used on site to measure rheology and density five times per day at two different temperatures in three well sections. The data was automatically sent to PRESSPRO RT real-time downhole performance measurement software.

By using the RheoProfiler rheometer and PRESSPRO RT software in combination, the use of high-viscosity pills was reduced by 33% in the 12 1/4-in section and by 90% in the 8 1/2-in section, saving the operator USD 15,000 in chemical products used. Additionally, fluid disposal was reduced by 300 bbl in the 12 1/4- and 8 1/2-in sections, reducing the environmental impact. Overall, these improvements reduced the anticipated well cost by USD 18,000.
