Repurposing Oil Wells Significantly Boosts Geothermal Heating Project Viability

Reusing depleted hydrocarbon wells for geothermal district heating dramatically reduces upfront investment and project risk, making renewable energy more economically accessible.

Energies · 2023

Key Findings

01Repurposing hydrocarbon wells for geothermal use significantly reduces investment costs and mining risk.
02Both case studies demonstrated positive economic indices when heat tariffs were aligned with 2020-2021 market values.
03Reusing existing wells offers a more economically attractive pathway to geothermal energy compared to developing new geothermal sites.

Application

Design takeaway

When designing new energy systems, prioritize the integration and repurposing of existing, underutilized infrastructure to enhance economic and environmental sustainability.

How to apply

Investigate local brownfield sites or abandoned industrial infrastructure for potential repurposing into renewable energy generation or other sustainable systems.

Project actions

01Research local abandoned industrial sites or infrastructure that could be repurposed for a sustainable project.
02Consider the economic benefits of using existing materials or structures in your design.

Method & Evidence

AimTo assess the feasibility and economic viability of repurposing existing hydrocarbon wells for geothermal district heating compared to developing new geothermal resources.

MethodComparative case study analysis with economic modelling.

ProcedureThe study assessed geothermal resources in two Italian locations: one with depleted hydrocarbon fields and another with documented geothermal potential. Methodological tools were developed to evaluate municipal energy demand and project economics for both scenarios. Economic indices were calculated based on assumed heat tariffs.

ContextUrban energy infrastructure, renewable energy development, and resource repurposing.

Variables

IVMethod of geothermal resource access (repurposed hydrocarbon wells vs. new geothermal wells).

DVProject economic indices (e.g., investment cost, profitability, risk).

CVGeothermal resource potential, municipal energy demand, heat tariffs.

Strengths & Limitations

Strengths

+Provides a clear economic and risk-based argument for repurposing infrastructure.
+Uses specific case studies to support its claims.

Limitations

Not all old wells or industrial sites are suitable for repurposing; detailed site-specific geological and structural surveys would be required.

Reliability & validity

The study's reliability is supported by the use of specific methodological tools and economic modelling. Validity is enhanced by comparing two distinct case study contexts, though the generalizability might be limited by the specific geological and market conditions of the Italian sites.

Think critically

To what extent does the 'mining risk' reduction in repurposing wells offset potential unforeseen geological challenges or the need for specialized conversion equipment?

Design Principles

"Leverage existing infrastructure for new sustainable applications to minimize resource expenditure and accelerate adoption."

This insight directly addresses the design curriculum topic of Resource Management by highlighting innovative strategies for utilizing existing infrastructure to access renewable energy. It demonstrates how designers can consider the entire lifecycle of resources and infrastructure, moving beyond single-use paradigms to achieve greater sustainability and economic efficiency in energy systems.

What This Means for Your Design

It's cheaper and less risky to turn old oil wells into hot water sources for heating cities than to dig for new geothermal spots.

How to use in your project

1.Use this insight to justify choosing a design solution that repurposes existing materials or infrastructure, highlighting the economic and environmental benefits.
2.In your analysis, discuss how your design minimizes waste and maximizes resource efficiency by building upon existing elements.
