Abstract: Formation drilling in abnormally high formation pressure zones adversely affects well construction efficiency.
The application of barite-free potassium formate-based drilling fluid ensures high-quality wellbore cleaning and minimizes the irreversible process of formation damage.
The impact of potassium formate-based drilling fluid and oil-based drilling fluid on core samples permeability was assessed, the applicability of drill-in fluids mentioned above was validated
