  • Patent number: 11001741
    Abstract: The present invention relates to an aqueous solution for drilling wells in low-gradient formations and is made up of products from three chemical families, namely a high molecular weight polymer mixture, an inhibitor, and an amine mixture. The solution is mixed with a seawater liquid base. The solution substitutes invert emulsion and was designed to control swelling, dispersion, and migration of fine colloidal materials, and the fluid can drill high pressure gradient intervals and be formulated to resolve any challenge presented by the formation. The system with the solution is environmentally-friendly and complies with the required main functions of the drilling fluids while also providing a high inhibition control by swelling and dispersion of clay zones, due to the polymeric nature of the materials with which it is formulated.
