Keywords: potassium formate, return permeability, abnormally high formation pressure, weighted drilling fluids

Annotation:

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.
