Latest Patents

Castillo’s listed patents focus on treatment fluids designed to dissolve specific oxides encountered in wellbores.

“Dissolution of manganese oxides in a wellbore” describes a treatment fluid containing an activator, an acid or acid-generating agent, and an aqueous base fluid. The activator may be selected from hydroxylamine, isopropyl hydroxylamine, ethanolamine, amino alcohols, their salts, or combinations of these materials. The fluid is introduced into the wellbore and brought into contact with manganese oxide to dissolve it.

“Dissolution of titanium-iron oxides and iron oxides in a wellbore” describes a treatment fluid that combines an activator with an acid or acid-generating agent and an aqueous base fluid. Listed activators include chlorophyll, pheophytin, hydroxylammonium chloride, dopamine, crown ethers, cryptands, ethanolamine, trihydroxamate-containing siderophores, their salts, and combinations. The fluid contacts titanium-iron oxide, iron oxide, or both to dissolve the targeted material.
