Welcome to a
deeper change.

Now is the time to act. As a society, we aim to reduce greenhouse gas emissions to zero in the medium term. Decisive potential for reducing greenhouse gas emissions must be released in the generation of energy and heat. In order to achieve our climate goals, it is necessary to redesign the generation of energy and heat, above all: through the use of renewable energies. In Germany we have the unique opportunity to develop geothermal energy as a domestic resource and to establish it worldwide as a regenerative energy source. Its global potential provides opportunities for know-how exchange. From Germany to the world.

The decarbonization of the (energy) industry can only succeed if we promote and further develop renewable energies. Photovoltaics, water and wind power are on everyone’s lips.

Geothermal heat, on the other hand, leads a gloomy existence – for now. Near-surface energy generation with geothermal probes is quite common. They usually supply individual buildings by means of boreholes and heat pumps. However, deep geothermal power plants, which generate energy from a depth of up to 6 kilometers and supply entire towns, businesses or districts with heat, can only be found occasionally. The technology offers great advantages, especially in the area of ​​heat generation, which could make it a strong pillar in the energy mix of the future.

In addition, deep geothermal energy delivers what we need: heat. More than 50 percent of the energy consumed in Germany is used to generate heat. Much of it still comes from fossil fuels: oil, natural gas and coal. To put it bluntly: These energy sources are not naturally warm. In order to convert fossil fuel into heat, it is burned. This results in process losses. The energy potential is not fully used. This transformation is not required with geothermal energy. This makes it particularly efficient, when it comes to providing heat only.

The heating sector plays a key role in climate protection and the successful transformation of energy supply. There have long been technically mature and very efficient technologies that not only minimize energy consumption, but can also generate energy in a climate-friendly manner: Geothermal energy can make a contribution to the decarbonization of heat or in the area of ​​process heat.

Regionally different approaches are required that take into account the existing infrastructure and available renewable energy sources on site. Local companies therefore play an important role in the intelligent use of renewable energies. Tomatoes from the Netherlands have long thrived with geothermal energy. Be creative as well and get in touch with neowells.

Due to the heat transition, the entire energy industry is changing. Denmark, which is regarded as a pioneer of the energy transition leads the way. A way to more energy autonomy. This means that citizens, local companies and municipalities take their energy into their own hands with their own initiatives and systems, be it with wind or water power, with solar energy or with deep geothermal energy. This not only makes us independent of large energy companies, we also inevitably protect the environment because we can rely on renewable energy sources.

At neowells, being a responsible corporate citizen is an integral part of the way we do business. It is reflected in our core values: constant and authentic care for ourselves, others and the environment, our reputation and our employees on whom we rely upon. We strive to always be sincere yet humble in our actions. neowells acts openly, transparently, and inclusively. neowells is proud of its North German roots and acts down-to-earth and always authentically. This claim extends to all levels of the company. Sustainability is thereby an important driver in all we do and in the centre of our approach.

It is our aim to make each other successful without losing sight of our core values. neowells stands for value-based, entrepreneurial behaviour. Everything we do is reflected in our name.

As a recognized well expert with international experience in both offshore and onshore sectors, Marco has travelled the world. He has been involved in a large number of projects. The doctor and graduate engineer for mining and petroleum technology knows how to holistically supervise wells throughout their lifecycle, from planning and operation to workovers and abandonment. Marco is passionate about good, coherent, efficient planning and has the necessary interest to detail. His experience taught him that 80 percent of operational problems can be made and avoided in the planning phase. Even during his studies and theses, Marco dealt with the modernization and digitization of the planning process. Later, as chief engineer and manager of the drilling department of a large, globally operating company, he succeeded in making the knowledge in the heads of the experts available to a larger team through methodology and modern means of communication. Marco knows: Success is not an orphan, but has many mothers and fathers.

With his practical training as an industrial mechanic and his subsequent mechanical engineering studies, Andre laid the foundation for his career. He quickly realized that the future of successful companies depends above all on their technical progress.
Andre has been working in the oil and gas industry since 2005. In 2007 he founded the company GOT German Oil Tools in Vechta with his business partners and managed it successfully until it was sold in 2017.
When the opportunity arose, he turned his personal dream of studying business psychology into reality. Within six semesters, Andre gained new knowledge and completed his studies at the Osnabrück University of Applied Sciences to start his entrepreneurship at neowells with full enthusiasm.

Since deep geothermal energy is yet to become a widespread technology for generating energy, developers and service providers for implementing a deep geothermal energy project are still few and far between. neowells is the game changer: the team has many years of international experience and an established network at renowned oil and gas companies, geothermal and project developers as well as classic well technology suppliers. neowells bundles individual expertise and quality through technology and methodology in order to professionalize and standardize deep geothermal energy. neowells thus contributes to your project success.

Equipped with many years of experience in well engineering and driven by the will to accelerate the heat and energy transition, neowells is a company of change: The objective of the two founders Andre Varnhorn and Marco Meirich is to safely guide and shape the end of energy generation from fossil fuels. Geothermal as a source of energy deserves a breakthrough, which Andre and Marco aim to achieve with expertise and new ideas.

For neowells, asset integrity and management is an important element for the successful expansion of deep geothermal activities in Germany and beyond. Only a professionally installed and regularly checked system works efficiently and safely. Neowells plans, designs, monitors and guarantees the long-term stability and technical integrity of the asset and thus helps to ensure that the safety of deep geothermal wells in the interaction between operators, planning companies, drilling contractors and authorities, but also trust of citizens and communities, is guaranteed in the long run.

Deep wells are the means for a safe and efficient use of underground resources. They establish the connection between the resources underground and the surface. If people want to use resources, the protection of life, health, nature and the environment is the top priority. A well is considered intact (tight) if the fluids it contains are safely controlled at every possible combination of pressure and temperature. neowells helps to ensure this with its expertise and experience in every phase of a project.

Neowells offers integrity related services that extend over the lifecycle of the assets including wells:

• Comprehensive integrity and barrier analysis
• Recommendations to ensure integrity
• Proofs of Integrity
• Repair and recovery recommendations
• Design principles and well designs
• Operating limits and safety measures
• Operational monitoring and maintenance
• Risk analysis and management
• Reports, audits and documentation

A well barrier is an impenetrable object that prevents the uncontrolled release of any media throughout the lifecycle of a well. In the case of deep wells, not just one, but usually at least two such independent barriers are relied upon. The secondary well barrier is a back-up for the primary well barrier and allows safe operation in any situation. Neowells supports with its experts the planning, manufacturing, monitoring and, if necessary, repairing the barriers.

Well Planning and engineering go through many phases from the idea to the successful construction and operation of a geothermal project. These phases have different requirements to achieve the ultimate goal of full asset integrity, but they all have elements and procedures in common. Neowells is your capable partner in the development of design principles, design, construction, operation and abandoning of wells.

Deep wells have been drilled on an industrial scale since the mid-19th century. The state of the art of making, operating, abandoning wells as well as the applicable legal regulations have continuously developed since then. They have reached a high standard due to long standing experience. Neowells plans, creates, operates, repairs and backfills wells to stringent local and internal standards. The safest, not the lowest common denominator, counts.

The appropriate design and selection of the barrier elements, their adequate construction and intended use, the verification and maintenance of their effectiveness through inspections, tests and maintenance measures are key aspects of an asset integrity management system. Operational barriers are a combination of practices, procedures, monitoring and control systems. Based on acceptance criteria, neowells creates customer-specific integrity management systems including control and maintenance plans, thus ensuring well documented and controlled safety over the life of the well.

Providing the world with the energy it needs, requires efficiency from start to finish. We at neowells believe that the responsible use of geo-resources, especially geothermal energy, is more than a duty – it is an opportunity.

The extraction of geothermal heat thanks to deep geothermal energy is possible in many areas of Europe. In Germany, predominantly in the North German Plain, the Molasse Basin and the Upper Rhine Graben. But efficient wells are also possible elsewhere. Knowledge of the subsurface is crucial. Is your location suitable for a deep geothermal well? Ask neowells!

The earth glows below our feet. Only the outermost crust on which we live is comparatively cool. The earth’s core, on the other hand, has a temperature of around 6,000°C. The temperature rises by about 3 to 5° Celsius for every 100 meters that we move towards the center. The energy potential of geothermal heat is so great that it could cover the current energy requirement 100,000 times.

We are literally sitting on an inexhaustible, natural energy reservoir that could be – and should be – an important pillar in the transition to renewable energies! In order to use geothermal heat industrially, we need deep wells.

Similar to oil and natural gas extraction, a drilling rig is used to drill 2,000 to 6,000 meters deep into the earth’s crust.

The basic principle of a classic geothermal power plant is simple. It all starts with wells: a production well and a re-injection well. The production well enters deep into the thermal water deposits. If water is not flowing naturally, hot water then reaches the surface via a production pump. By means of heat exchangers, the energy can then either be used to generate electricity or provide heat. Depending on the prevalent geological conditions, different methods for heat extraction may be possible as well.

The generation of energy becomes regenerative in that the cooled thermal water is fed back into the reservoirs via a re-injection well for the water to heat up again. The distance between the production and the re-injection well must be large enough so that the water introduced has no thermal influence (“thermal shortcut”) on the production well. One wellpad location is generally sufficient for this, as wells are drilled directionally i.e. not vertically. Deep geothermal energy is particularly efficient when it comes to providing heat to consumers, since there are fewer process losses compared to other energy sources.

Whether or not a well is suitable for a heating network or for generating electricity depends on the temperature and the mobility of the thermal water. 60°C may already be suitable to generate sufficient heat. A temperature of at least 120°C is required to generate electricity using a turbine.

The deeper we drill into the earth’s crust, the warmer it gets: the thermal energy that we can generate from there is renewable and inexhaustible by human standards.

Geothermal energy is independent of season and weather: Since the energy is generated deep inside the earth, the seasons and the local climate have no influence on its extraction. Deep geothermal energy thus offers reliable and baseload-capable energy supply.

Coal, gas and nuclear power plants are huge and emit massive amounts of water vapor. Wind turbines can be seen from miles away and photovoltaic systems sometimes cover large areas. In contrast geothermal plants are rather small. The classic system is quiet and usually does not emit any water or vapor at all.

About half of the energy consumption in Germany is used to generate heat. With deep geothermal energy, large parts of it could be generated regeneratively in the long term – and thus enormous amounts of CO2 can be saved. No doubt, deep geothermal energy will be an important component in achieving climate protection goals.

The German government offers attractive funding opportunities for geothermal projects within the framework of the Renewable Energy Sources Act via the Federal Ministry for Economic Affairs and Energy. Furthermore, deep geothermal energy systems are funded from the German MAP (market incentive program of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety) through low-interest loans with repayment subsidies. The KfW can use this to grant loans. Moreover, nature conservation organizations such as Greenpeace and NABU promote deep geothermal energy.

Expertise and diligence: With neowells and its partners, a geothermal project is safe from the start. Thanks to sophisticated planning processes, many years of project and drilling experience, complete documentation and responsible implementation, neowells guarantees a sustainable concept and maximum reliability.
