Experimental investigation of new additive to optimize the properties of synthetic-based drilling fluid

This research focus on the formulation, development and testing a new additive in synthetic based drilling fluid include of amine-treated Quebracho agent . Traditionally invert emulsion drilling fluids have been formulated to achieve optimum performance of drilling operation because of the high level of wellbore stability and penetration rates by these drilling fluids. Amine-treated Quebracho agent is compatible with other chemical additives in Synthetic-Based Fluids. The laboratory research was run to evaluate the temperature effect on rheological and filtration properties of synthetic-based fluids under heated aging for 16hours at different temperatures up to 400 °F. Experimental results demonstrate that new synthetic sample including amine-treated Quebracho agent improves the thermal stability of polymers. This new agent have high biodegradability and a lower toxicity (environmentally friendly) so it was used as a synthetic based mud additive for oil well drilling fluids .The evaluation includes study of the rheological properties, filtration and thermal properties of the synthetic based–muds formulated with the new amine-treated Quebracho agent in comparison with the reference commercial synthetic based mud. The results showed that the rheological and filtration properties of synthetic fluid are enhanced. Thus, amine-treated Quebracho improved the thermal stability of polymers in synthetic based drilling fluids.
