Energy transition

Providing geothermal energy from natural heat and protecting the atmosphere from damaging greenhouse gases

Applying oilfield experience to the renewable energy sector

Geothermal and CCS operators can now benefit from more than 25 years of expertise in building innovative well technology - combined with the low-impact and lightweight nature of our solutions, we’re facilitating novel developments in:

  • Geothermal well construction
  • Enhanced Geothermal Systems (EGS) for high temperature power generation
  • Carbon Capture Storage (CCS) well construction
  • Rigless and urban intervention solutions – for low temperature direct use applications

A steppingstone for more sustainable energy

Welltec® has more than 25 years of experience in providing innovative well technology to the energy industry. In 1994 Welltec initiated its wireline intervention solutions through the invention of the Well Tractor®.

In 2010 Welltec began offering advanced Completion solutions following the design of a metal expandable packer – Welltec Annular Barrier (WAB®).

Since then, the WAB portfolio has provided high value to operators across the globe, providing zonal isolation, reducing the use of cement for well construction, minimizing and eliminating Sustained Casing Pressure (SCP) and leakage to the atmosphere.

With the environmental improvements already provided by Welltec’s solutions, this has provided a natural steppingstone to offer the same benefits to renewable energy operators, with WAB technology already applied in geothermal well construction and revival operations. 

 

Geothermal deployment

For an Asia-Pacific operator, we combined metal expandable packers (WAB) with cementing to achieve zonal isolation and revive a geothermal well, in highly challenging conditions. The achievements from this operation are now providing the foundation for a co-authored academic paper.

Innovative intervention tools and completion products for renewable energy

Welltec's e-line tools are so compact, lightweight and environmentally friendly, they can be deployed within a densely populated urban area.
For well construction under acidic corrosion, extreme pressures and temperatures up to 300°C – see our new WAB® solutions portfolio with all-metal, high-temperature packers.
