Title (EN) A WATER-BASED DRILLING FLUID COMPOSITION HAVING A MULTIFUNCTIONAL MUD ADDITIVE FOR REDUCING FLUID LOSS DURING DRILLING
(FR) COMPOSITION AQUEUSE DE FLUIDE DE FORAGE CONTENANT UN ADDITIF MULTIFONCTIONNEL DE BOUE PERMETTANT DE RÉDUIRE LA PERTE DE FLUIDE LORS D'UN FORAGE
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.
(FR) La présente invention concerne une composition aqueuse de boue permettant d'effectuer un forage, un forage de couche et une complétion, la composition contenant des micro- ou nano-particules et servant à l'extraction des hydrocarbures. La composition aqueuse de boue de forage contient suffisamment d'eau pour rester fluide, ainsi qu'une boue de forage contenant des particules. Les particules sont choisies parmi les microparticules, les nanoparticules et leurs combinaisons. La composition aqueuse de boue de forage contient également une quantité efficace d'un additif multifonctionnel de boue, qui contient une poudre d'enveloppe de graine de psyllium. La composition aqueuse de boue de forage est capable de stabiliser les particules et de les maintenir parfaitement dispersées, même en l'absence d'un tensioactif.
