  • Oil-based drilling fluids containing an alkaline-earth diamondoid compound as rheology modifier
    Patent number: 10087355
    Abstract: An oil-based drilling fluid and method of preparing an oil-based drilling fluid are disclosed. The oil-based drilling fluid comprising a base oil continuous phase, an aqueous discontinuous phase, and at least one rheology modifier. The at least one rheology modifier including an alkaline-earth diamondoid compound. The method of preparing the oil-based drilling fluid including mixing a base oil, at least one emulsifier, and at least one wetting agent to form a first mixture, adding and mixing at least one rheology modifier into the first mixture to form a second mixture, adding and mixing at least one fluid-loss control additive into the second mixture to form a third mixture, adding and mixing a brine solution into the third mixture to form a fourth mixture, and adding and mixing a weighting additive into the fourth mixture to form the oil-based drilling fluid.
