Abstract:Carbonate reservoirs are often characterized by high pressure and high content of H2S and CO2. For these reasons, drilling the reservoir is the most challenging activity for such fields and long-term zonal isolation across the reservoir section is one of the primary requirements. The work describes the development, laboratory evaluation, implementation and long-term assessment of self-healing properties for H2S/CO2 resistive, low Young's modulus, expandable cement system. The 2.05 SG cement system was speciall… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
