  • Patent number: 10400339
    Abstract: The invention relates to compositions, methods and preparation of such compositions to protect metals from corrosion, especially acid corrosion. The compositions of this invention may be added to acids to protect metals from their corrosive influence, particularly at elevated temperatures. These compositions are of particular utility in the oil and gas (petroleum) industry. Also disclosed are “corrosion inhibition intensifiers” to enhance the corrosion inhibition properties of other corrosion inhibitors. Formulations which control ferric ions in acidic solutions are also disclosed. These may be combined with inhibited acids and some compositions provide both corrosion inhibition and ferric ion control.

  • Patent number: 10034478
    Abstract: Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing.

  • Publication number: 20160032180
    Abstract: The invention relates to polymeric coatings on proppants. These coatings have antimicrobial materials incorporated within these coatings. Preferably the antimicrobial materials have low water solubility. These antimicrobial agents are incorporated as particles whose surfaces are modified or these may also be incorporated within porous particles which are then added to the coating formulations. The antimicrobially active agents are incorporated in a fashion so that they can be released from these coatings in the environment of the proppants.
