Latest Patents

One of Sarah's latest patents focuses on organophilic clays and drilling fluids containing them. The invention describes an organophilic clay that comprises a smectite-type clay ion exchanged with quaternary ammonium ions. Notably, at least 75 mol-% of these quaternary ammonium ions are bis-(2-hydroxypropyl)-dimethylammonium fatty acid esters. Furthermore, at least 90% of the fatty acid moieties of these esters have a structure RC(O), where group R is a linear alkyl or alkenyl group containing from 9 to 21 carbon atoms. This organophilic clay is particularly useful for thickening oil-based compositions, especially drilling fluids for drilling oil or gas wells that comprise an oil phase.
