Abstract

Abstract This article focuses on the development and characterization of one-part rock-based geopolymer slurries utilizing Brazilian rock precursors for well construction and plugging and abandonment applications (P&A). The study presents the fluid-state and solid-state properties of these geopolymers, X-ray diffraction (XRD), and Scanning Electron Microscopy (SEM) to understand the precursors' microstructure and reaction level. The effect of temperature and pressure on compressive strength development was investigated. By altering these parameters, the study aimed to understand the impact of different environmental conditions on the strength development of the geopolymer material. Technological tests were performed according to API RP 10B-2. Compressive strength tests were conducted to determine early strength development and thickening time, and UCA tests were carried out. Post-curing, Retvied analysis through XRD was performed to examine microstructure and reactivity. Finally, fluid-state properties were also assessed, including thickening time and viscosity. The strength development of the geopolymers is observed to be time and temperature-dependent, as shown through ultrasonic strength data. The final product has a dense structure, and its long-term performance will require evaluation to determine its sealing capability and volume change as a barrier material. The research demonstrates the potential of rock-based geopolymers for well cementing and well abandonment applications using a Brazilian rock precursor.
