Latest Patents

One of Lawson's latest patents is for additives for water-base drilling fluid and process. This invention discloses an additive for water-base drilling fluid compositions used in drilling subterranean wells. In one embodiment, the additive is a sulfonated copolymer of recurring units of a maleimide monomer and recurring units of a vinyl monomer. In another embodiment, the additive is a sulfonated terpolymer of recurring units of a maleimide monomer, recurring units of a vinyl monomer, and recurring units of a carboxyl-containing monomer. The patent also details water-base drilling fluid compositions that contain the additive and a process for drilling subterranean wells using these compositions.

Another significant patent by Lawson is a process for sulfonating polymers containing dicarboxylic acid cyclic. This process involves producing sulfonated polymers that contain styrene moieties and cyclic imide moieties. It comprises reacting a styrene/maleic anhydride copolymer with a primary amine to produce a polyimide, followed by sulfonation. Both the imidization step and the sulfonation step are conducted in a solvent that is inert to both reaction steps, such as nitrobenzene.
