Title: (EN) Method for reducing fluid loss during drilling of a hydrocarbon formation using a water-based drilling fluid composition having a multifunctional mud additive
Abstract:
(EN)

Embodiments of the invention provide a drilling, drill-in, and completion water-based mud composition containing micro or nanoparticles for use in hydrocarbon drilling. In accordance with at least one embodiment, there is provided a method of drilling a hydrocarbon formation, including contacting the hydrocarbon formation with a water-based drilling mud composition while drilling or completing a well. In accordance with at least one embodiment, the water-based drilling mud composition includes water, the water being present in an amount greater than about 90 wt % of the water-based drilling mud composition to maintain flowability of the water-based drilling mud composition; drilling mud having microparticles, nanoparticles, and combinations thereof; and a multi-functional mud additive in an amount of 0.8 wt % of the water-based drilling mud composition, the multi-functional mud additive comprising psyllium husk powder.
