Title: Innovations of Lena Petrozziello
Introduction
Lena Petrozziello is an accomplished inventor based in Langenselbold, Germany. She has made significant contributions to the field of polymeric scale inhibitors, particularly in the oil and gas industry. Her innovative work focuses on developing solutions to combat metal sulfide scale formation in wells.
Latest Patents
Lena holds a patent for an "Iron sulfide inhibitor suitable for squeeze application." This invention involves a polymeric scale inhibitor composition designed to inhibit metal sulfide scale formation in wells. The composition consists of 80-82 mol % of a first monomeric unit, specifically 2-acrylamido-2-methylpropane sulfonic acid (AMPS). Additionally, it includes 2-18 mol % of a second monomeric unit selected from N-vinyl formamide, N-vinyl pyrrolidone, and diallyl dimethyl ammonium chloride. Furthermore, the composition contains 2-18 mol % of a third monomeric unit chosen from acrylic acid, methacrylic acid, esters of acrylic acid or methacrylic acid with an alcohol having 1 to 4 carbon atoms, and carboxyethyl acrylate. These polymeric scale inhibitors exhibit superior adsorption characteristics on rocks, allowing for effective scale inhibition over extended periods, making them particularly suitable for downhole applications via field scale squeeze treatments.
