Abstract

Summary

CO mineralisation in peridotite formations offers a promising approach for durable and secure CO sequestration. However, modelling fluid flow in fractured peridotites can be challenging due to heterogeneity and stress-dependent permeability.

This study presents results from two pilot injection tests in the UAE and Oman, demonstrating fracture network responses to variable injection pressures. Electromagnetic surveys and wireline well logging data were used to initialise fracture permeability in reservoir models for both sites. Additionally, stress-dependent permeability was incorporated to account for variations with injection pressure.

The models were calibrated against field data from the injection tests, revealing that a broad range of injection pressures is necessary for comprehensive assessment. Notably, the simulated water plume closely aligned with time-lapse electromagnetic survey results, adding more confidence in the modelling approach for fluid flow in fractured peridotites.
