Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development

Summary Shallow-depth cementing presents unique challenges due to its low temperature and pore pressure characteristic. The curing process of the cementitious material is typically prolonged at temperatures resulting in a delayed process. use low-density slurry mitigate introduces another challenge, as it leads reduction final compressive strength. On other hand, operation requires develop enough strength swiftly be able efficiently continue next drilling operation. In addition, presence flow zones such shallow gas water increases complexity There have been many developments materials for shallow-depth rapid-hardening cement tight cement. However, there little research focusing on performance evaluation each low-temperature conditions. This paper aims present thorough cementing. incorporated are American Petroleum Institute (API) Class G cement, geopolymer. Geopolymer included evaluate potential green alternative Portland-based sets characterization were conducted during liquid, gel, solid phases. samples prepared under wide-ranging typical bottomhole pressures sections. result shows different performances behavior development reactivity, which necessitates further these materials.
