Overview
An enhanced oil recovery (EOR) unit revives aging reservoirs by injecting CO2, steam, polymers, surfactants, or water to mobilize oil that primary production left behind. These operations run continuous injection plants, compression and heat-generation equipment, networks of injection and producing wells, and surface separation gear across a defined unit. Because pressurized fluids and chemicals move underground over wide areas, the exposures differ sharply from a simple producing well. A tailored EOR program may help coordinate property, pollution, equipment, and liability protection across the injection and recovery side of the operation.

Risk profile
EOR risk centers on subsurface integrity and the handling of injectants under pressure. A failed injection well, casing breach, or migration of CO2 or chemical flood fluids can contaminate groundwater, neighboring leases, or soil, and induced pressure changes occasionally raise seismicity concerns. On the surface, compression trains, steam generators, and high-pressure piping carry fire, rupture, and breakdown exposure, while chemical and CO2 storage adds release potential. Crews working around pressurized systems and elevated temperatures face injury risk, and operators frequently work under unit agreements and regulatory permits that impose specific financial-responsibility and insurance requirements.
Common risks
Injectant migration and groundwater contamination
CO2, steam condensate, or chemical flood fluids can migrate through a compromised well or formation, contaminating aquifers or adjacent leases and triggering cleanup liability.
Injection well or casing failure
Pressurized injection can rupture casing or cement, leading to surface releases, lost containment, and costly remediation across the unit.
Surface equipment fire and explosion
Steam generators, compressors, and high-pressure piping handling flammable and pressurized media create fire and rupture exposure at the plant.
Compression and generation breakdown
Mechanical failure of injection compressors or steam units can halt the flood program and idle production across the recovery unit.
Chemical and CO2 storage releases
On-site storage of injectant chemicals and CO2 introduces leak and release exposure that can affect workers, the public, and the environment.
Worker injury around pressurized systems
Crews servicing wells, valves, and hot equipment face burn, struck-by, and high-pressure release injuries.
Unit agreement and regulatory obligations
Working-interest partners and permitting agencies often require evidence of liability, pollution, and financial-responsibility coverage.

Why tailored insurance matters
Enhanced oil recovery blends a chemical or thermal process plant with subsurface injection across a wide unit, so a generic oil-and-gas policy rarely fits. Coverage should reflect the specific injectants used, the integrity of the injection wells, the value of compression and generation equipment, and the unit agreements and permits in force. A program coordinated across pollution, property, equipment breakdown, and liability may help ensure that a migration event or equipment failure does not leave gaps, subject to policy terms. Coverage availability depends on underwriting, well integrity records, and loss history.
Hypothetical claim examples
CO2 flood migration to a neighboring lease
Injected CO2 migrates through a formation and is detected on an adjacent property, prompting a contamination claim. An environmental liability policy may respond to investigation and remediation, depending on policy terms and the facts.
Steam generator failure halts injection
A steam generator suffers a mechanical breakdown and stops the thermal flood for several weeks. Equipment breakdown coverage may help with repair and resulting loss, subject to the specific policy, endorsements, and exclusions.
Compressor fire at the injection plant
A compressor ignites and damages surrounding surface equipment. Property coverage may help with repair and replacement, depending on policy terms and the cause of loss.
Hypothetical scenarios for illustration only. Coverage depends on the specific policy, endorsements, exclusions, and facts of each claim.
What affects insurance cost
- Type of injectant used (CO2, steam, water, or chemical)
- Number and integrity history of injection wells
- Value of compression, generation, and surface equipment
- Proximity to groundwater and neighboring leases
- Permit and unit-agreement insurance requirements
- Field crew headcount and payroll
- Loss history and remediation record
How much does it cost?
There is no single price for enhanced oil recovery unit insurance — it depends on which of these coverages you carry and the specifics of your business. As a rough guide, here are general national averages for the coverages this business commonly needs.
- Varies widely by operations and site risk — a quote is required
- $1,000–$3,000 per year, depending heavily on property value and location
- $200–$800 per year, often added to a property policy
- $500–$1,500 per year for many small businesses
- $500–$3,000 per year, driven largely by payroll and job class codes
- $1,500–$3,000 per vehicle per year
- $400–$1,500 per year per $1M of additional limit
These are general national averages shown for comparison only — not a quote. Actual premiums vary widely with underwriting and depend on the factors above and the specifics of your business, including size, revenue, location, claims history, and the limits you choose. See how we estimate costs.
Coverage considerations
- Match pollution limits to the migration potential of the injectant
- Confirm equipment breakdown for compressors and steam units
- Review financial-responsibility requirements in permits
- Assess sudden-and-gradual pollution coverage triggers
- Coordinate limits with working-interest partners
Common underwriting considerations
When insurers review a enhanced oil recovery unit business, they commonly evaluate factors like these. This is educational information — nothing here is collected or submitted.
- Operations performed — generation, distribution, extraction, or services — and where
- Regulatory permits held and compliance history
- Environmental exposures and containment or remediation practices
- Property and equipment values, including specialized and remote assets
- Payroll, employee count, and safety-program maturity
- Claims history, especially environmental and severe-injury losses
Common contractual insurance requirements
Contracts, leases, and licenses in this industry commonly impose insurance requirements such as these. Always review the specific wording in your own agreements.
- Master service agreements in energy commonly set high liability and umbrella minimums
- Operators require additional-insured status and waivers of subrogation from service contractors
- Regulators and permits frequently require pollution liability and financial-assurance instruments
- Right-of-way and land-use agreements carry liability requirements
- Lenders require property coverage on financed infrastructure
Common coverage mistakes
Mistakes businesses in this industry commonly make when arranging coverage — worth reviewing before you buy or renew.
- Relying on general liability for pollution claims that standard forms exclude
- Carrying limits below master-service-agreement thresholds
- Underinsuring remote or specialized equipment that is slow to replace
- Overlooking business income when a single facility drives most revenue
- Missing contractual-liability review on indemnity-heavy energy agreements
Frequently asked questions
Why does an EOR unit need pollution coverage beyond general liability?
General liability often excludes pollution, and injecting CO2, steam, or chemicals creates migration and contamination exposure. Environmental liability may help address cleanup and third-party claims, subject to policy terms.
Are induced seismicity concerns insurable?
Coverage for pressure-related ground movement is specialized and depends on underwriting and the specific policy. We can review options based on your injection program and location.
Does coverage extend to both injection and producing wells in the unit?
Programs can be structured to address surface equipment and operations across the unit. The exact scope depends on the policy, endorsements, exclusions, and the facts of each location.
How do unit agreements affect my insurance?
Working-interest partners frequently require evidence of liability, pollution, and adequate limits. We can help align coverage with your unit agreement, though availability depends on underwriting.
Is equipment breakdown separate from property insurance?
Often yes. Property typically covers external causes like fire, while equipment breakdown may respond to mechanical or electrical failure of compressors and steam units, depending on the specific policy.
What drives the cost of EOR insurance?
Injectant type, well integrity history, equipment values, proximity to groundwater, and loss history all factor in. Final pricing depends on underwriting and your specific operation.
