Assessment and development of technology for NAPL displacement from fractured media: experiments and modeling
Project goal: The main goal is to develop effective and environmentally friendly soil remediation technologies specifically designed for low-permeability fractured sites contaminated by non-aqueous phase liquids (NAPLs). The project aims to enhance remediation performance in accordance with Kazakhstan's Environmental Code standards.
Project description: The project involves creating and testing novel complex fluids, such as colloidal gas aphrons (CGAs) and polymer solutions, to enhance the removal of NAPLs from fractured geological media. Experimental studies at various scales, along with advanced numerical modeling, will provide insights into fluid behavior, ultimately supporting the design of scalable remediation methods.
Project facilitators: PI - Dr. Sagyn Omirbekov (Senior Researcher, NLA), Dr. Yerlan Amanbek (Nazarbayev University), Dr. Timur Merembayev (International Information Technology University), Dr. Bakbergen Bekbau (KMG Engineering LLP), Adil Baigadilov (BRGM, France), Ali Sipullayev (Research Assistant, NLA), Dana Sapobekova (Research Assistant, NLA)
Project partners: International Collaborators: Dr. Stéfan Colombano (BRGM, France), Dr. Maxime Cochennec (BRGM, France)
Realisation period: 2023-2025
Expected results: - Development of new eco-friendly fluids for the remediation of NAPL-contaminated fractured media.
- Reduction of residual saturation of contaminants to comply with Environmental Code standards.
- Advanced numerical models to predict fluid behavior in fractured geological formations.
- Scientific dissemination through high-quality journal publications and international conferences.
Methodology: The methodology consists of four interconnected work packages:
1. Literature review on colloidal systems, polymers, and surfactants.
2. Fluid characterization, including laboratory formation and testing of CGAs and polymers.
3. Multiscale experimental studies encompassing capillary tube flow tests, core-flood experiments, and two-dimensional tank tests.
4. Numerical modeling using UTCHEM, Eclipse 100, and tNavigator to simulate fluid flow dynamics and validate experimental outcomes.
