Arctic Drilling Fluid Formulation And Characrtization

摘要

Petroleum exploration and development in the Arctic region are considered to be extremely challenging. Among others, during well construction processes wellbore enlargement and kick can be mentioned. The problems are due to temperature increase as fluid ciriculating and exothermicity, heat realease as hydration reaction of cement components. Washouts of frozen soils reduce formation strength and results in poor cement jobs. This paper presents the formulation and characterization of drilling fluids for Arctic drilling.The overall analysis shows that synergy of NaCl and ethylene glycol exhibit good performance in terms of thermophysics and rheology properties.
