Repurposing Oil & Gas Assets for Energy Transition
This training covers the repurposing of oil and gas assets for energy transition uses. It works through screening assets for alternative use, CO2 storage conversion, gas and hydrogen storage conversion, geothermal conversion of wells and fields, data and infrastructure reuse, well integrity requirements for new service, regulatory and ownership issues, economics of repurposing against decommissioning and the decision framework for asset end of life.
Description
A mature petroleum asset has a reservoir, a seal, wells, pipelines, platforms and decades of subsurface data, and it has a decommissioning liability. Whether any of that has value for carbon storage, for gas or hydrogen storage, for geothermal production or for another use is a question most operators now face across their portfolios. The answer is site specific and usually negative for any given asset, which makes efficient screening valuable: establishing quickly which assets are worth assessing in detail and which are not.
This training provides that screening capability and the detailed assessment that follows. Screening assets for alternative use is established first, covering the criteria for each potential use and the order in which to apply them. CO2 storage conversion follows, covering the reservoir and seal requirements, the legacy well problem and the capacity assessment. Gas and hydrogen storage conversion are then developed. Geothermal conversion of wells and fields follows, covering the temperature and flow requirements and the realistic output from converted wells. Data and infrastructure reuse are then addressed. Well integrity requirements for new service follow. Regulatory and ownership issues are then developed. Economics of repurposing against decommissioning follow. The training closes with the end of life decision framework.
The legacy wells that make a depleted field attractive for storage are also what disqualifies most of them. A depleted field has a proven seal, known reservoir properties, existing infrastructure and extensive data, all of which favour it over a saline aquifer. It also has every well ever drilled through that seal, abandoned to the standards of its day. Assessing and where necessary remediating those penetrations is frequently the largest single cost in a depleted field storage project, and in heavily drilled fields it is enough to make the project uneconomic against a nearby aquifer with no wells.
Geothermal conversion of petroleum wells rarely produces useful power. A typical petroleum well in a sedimentary basin produces fluid at temperatures of sixty to a hundred degrees Celsius, which is below the range where power generation is efficient, and at flow rates far below what a geothermal power well requires. The realistic uses are direct heat, district heating and industrial process heat where a local demand exists, which is a much smaller market and requires the demand to be close to the well. Claims that large numbers of existing wells can be converted to power generation do not survive the temperature and flow rate arithmetic.
Decommissioning liability is the number that changes the decision. An asset with a large decommissioning cost and a repurposing option that defers or reduces that cost may be worth converting even where the new use is marginally economic in itself, because the avoided or deferred liability has real value. Conversely, a repurposing project that transfers the decommissioning obligation without eliminating it, and that requires capital of its own, may be worse than simply decommissioning now. The comparison has to be made on a full life basis including the liability, not on the new project's economics alone.
Finally, the subsurface data is often the most valuable asset. Decades of seismic, well logs, cores, pressure data and production history represent an investment that cannot be reproduced, and it has value for storage site characterisation, for geothermal assessment and for regional studies, including on acreage the operator no longer holds. Preserving that data in a usable form before an asset is relinquished or a team is disbanded is a low-cost action with a long tail of value, and it is routinely neglected during decommissioning.
By the end of this training, participants will be able to:
- Screen petroleum assets for alternative use potential
- Apply screening criteria for storage, geothermal and other uses
- Assess depleted fields for CO2 storage conversion
- Assess legacy well risk and remediation cost
- Assess reservoirs for gas and hydrogen storage conversion
- Assess geothermal conversion potential realistically
- Identify value in subsurface data and infrastructure
- Specify well integrity requirements for new service
- Address regulatory, ownership and liability issues
- Compare repurposing against decommissioning on a full life basis
The training works on mature asset portfolios with real data. Participants screen assets for each alternative use, assess legacy well populations and estimate remediation requirements, and build repurposing against decommissioning comparisons including liability. Geothermal conversion cases are assessed against temperature and flow rate requirements.
