Title: Amanda Sofia De Guimarães E Stepanha: Innovator in Hydraulic Cement Technology
Introduction
Amanda Sofia De Guimarães E Stepanha is a notable inventor based in Porto Alegre, Brazil. She has made significant contributions to the field of hydraulic cement technology, particularly in applications related to oil and gas reservoirs. Her innovative work focuses on enhancing the performance and durability of cement compositions used in challenging environments.
Latest Patents
Amanda holds a patent for a hydraulic cement composition, process, and use. This invention describes a hydraulic cement composition that exhibits increased resistance against carbon dioxide (CO2). It is designed for application in reservoirs such as oil and gas, as well as in carbon capture and storage (CCS) wells. The composition improves the performance of cement paste formulations, making it suitable for primary and secondary cementing, recovery, and plugging operations in high CO2 environments. This technological advancement ensures the integrity of wells in CO2-rich settings for extended periods without requiring additional interventions, while also reducing costs compared to traditional class G cement. Furthermore, it provides sufficient chemical resistance for enhanced oil recovery (EOR) and enhanced gas recovery (EGR) by injecting high levels of CO2, thereby increasing reservoir pressure throughout the extraction period.
