Latest Patents

Cristante holds a patent titled "Use of microcapsules containing acids in its interior and method of treatment using a scale inhibitor activated by said microcapsules." This invention proposes the use of microcapsules that contain acids to adjust the pH of scale inhibitors in oil reservoirs. The microcapsules consist of an inner moiety with organic or inorganic acid and an outer moiety made of an oil-soluble polymeric material that functions at the reservoir temperature. The microcapsules are designed to open due to the reservoir temperature, releasing the acid into the corrosion inhibitor and thereby altering its pH. The method involves several steps, including preparing the scale inhibitor product, pumping the inhibitor solution into the standpipe manifold, adding the acidic microcapsules, and injecting the mixture into the production well column. Cristante's patent represents a significant advancement in the treatment of scale in oil reservoirs.
