4th AAPG Geothermal Cross-Over Workshop Harvesting the technical, environmental and commercial synergies between the O&G and geothermal sectors

9-10 March 2021
Utrecht, Netherlands

Although years of subsurface experiences are available for the fast-growing geothermal sector, real-life examples of true cross-fertilization that exceed good neighborliness are limited. For one is the subsurface (play) leading, while for the other the surface (demand) is leading. It is a difference of local markets in comparison to a huge world market. And the budgets available and the revenue streams are incomparable, as well as the economic lifetimes, whilst the risk exposure is comparable.

But despite the differences, the close collaboration is critical to enable the achievement of ambitious sustainable heating and electricity supply objectives. We believe that from a more integrated development, operation and collaboration, we can both preserve and create more societal, economical, technical and commercial value.

The continued changing global energy supply and demand landscape observed over the last 10 years, is currently leading to an unprecedented rethinking of energy industry priorities and long-term strategies. The need for improving the knowledge and technology transfer are sometimes recognized, but mostly not acted upon. In the field of exploration, development, production and abandonment the opportunities and synergies – although not yet widely valorized – are present and are the topics of our workshop.

Discussing and sharing experiences, best practices and knowledge on how to get the best from both the O&G sector and the geothermal sector, in order to both accelerate and improve the quality of the geo-energy transition, are the goals of a 2-day workshop organized by the AAPG and IGA in Utrecht (NL) on March 9 – 10, 2021

The workshop will offer an open forum to integrate two geo-energy communities where technical, environmental, social and business aspects associated with geo-energy exploration, development and production activities will be presented and discussed. The workshop will evolve around a two day program where on the first day a series of key-notes on all themes will provide the basis for in depth discussions, and where on the second day the community will share their knowledge and experiences through presentations and posters to explore the synergies in smaller groups. All with the purpose of coming to a final take-away: which opportunities should be redeemed, which synergies should be nurtured and which bridges are still to be build?


To contribute to the success to this event and join the community in maturing the crossover, please consider submitting your paper for an oral (on the 2nd day) or poster presentation (on both days) on one or more of the following themes, with focus on sharing both knowledge and (best) practises:

1. Technical synergies:

  1. Geothermal resource estimation – Similarities on resource estimation for O&G (incl. unconventionals). Resource classification and mechanisms to quantify estimation resources.
    • Is there an optimal development of resources (ODR)? How do you execute a sustainable development plan for geothermal projects? Can unitization be an issue and if so how is this regulated?
  2. Cost optimization and de-risking:
    • Drilling efficiency – optimization and improvements
    • Well & completion design
    • ESP selection and operation
    • Lowering the Opex/ The value of FEED
  3. Engineering synergies
  4. Drilling synergies

2. Environmental/ societal synergies:

  1. How to integrate geothermal heat sources in an urban environment? How can a sensible mining operation be executed in an urban environment?
  2. Infrastructure: opportunities of re-use of sites, wells or pipes
  3. Safety of supply: opportunities, synergies of a complex hybrid energy system
  4. d) Strategic Stakeholder Management/ Social Risk Management of projects –What is the narrative of O&G surrounding communities? How do O&G companies explain what they do? What is the geothermal narrative? Need to involve the public: “A communication perspective?”

3. Business/ commercial synergies:

  1. Integrated development and exploitation of geo-energy projects – e.g. how to go from one project to portfolio development, create joint operation/drilling sequences, joint operating and maintenance services and new collaboration/project governance
  2. How can an O&G company make sense of geothermal?
    • Business opportunity: What is the broader picture? Financial viability. Business opportunity within geothermal for O&G majors. Scalability of geothermal. What is the competitive advantage? “Is the pie large enough to be attractive for the O&G majors?”
    • Project financing of geo-energy projects
    • Risk-sharing approaches: what public or private mechanisms can be put in place?
  3. Parallel licensing processes – Differences between O&G and how this works for geothermal. Is it more efficient for O&G?
  4. Project finance in geo-energy projects
  5. Who are the (final) users?
