Title: (EN) Water-based drilling fluid composition having a multifunctional mud additive for reducing fluid loss during drilling
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. The water-based drilling mud composition includes water present in an amount sufficient to maintain flowability of the water-based drilling mud composition, and drilling mud, which includes particles. The particles are selected from microparticles, nanoparticles, and combinations thereof. The water-based drilling mud composition also includes an effective amount of a multi-functional mud additive, which includes psyllium seed husk powder. The water-based drilling mud composition is operable to keep the particles stabilized and dispersed throughout the drilling mud composition in the absence of a surfactant.
