Chemical Sand Consolidation: From Polymers to Nanoparticles

Area of Science:

• Petroleum Engineering
• Materials Science
• Geology

Background:

• Unconsolidated sandstone formations in hydrocarbon reservoirs are prone to sand production.
• Chemical sand consolidation methods inject materials like furan resin and silicate non-polymers to bind sand grains.
• While effective in reducing sand, these methods can decrease formation permeability, impacting productivity.

Purpose of the Study:

• To review and evaluate chemical materials used for sand consolidation.
• To provide a screening tool for selecting optimal sand consolidation agents.
• To highlight advancements in sand consolidation techniques and their impact on performance.

Main Methods:

• Comprehensive literature review of chemical sand consolidation methods.
• In-depth evaluation and comparison of various chemical agents, including polymers and nanoparticles.
• Analysis of the trade-off between rock strength enhancement and permeability reduction.

Main Results:

• Traditional polymer-based consolidation can reduce permeability.
• Nanoparticle utilization represents a progressive improvement in sand consolidation.
• Nanoparticle agents offer acceptable rock strength with insignificant permeability reduction.

Conclusions:

• Nanoparticle-related materials are highly recommended for sand consolidation.
• These agents effectively enhance rock strength while minimizing negative impacts on formation permeability.
• Optimized sand control performance can be achieved through judicious selection of nanoparticle consolidation agents.
