Energy transition - applying O&G experience to the renewable sector

Ever since our founder started the company more than 25 years ago, the environmental factor was always an important aspect of Welltec's value proposition. Our lightweight Intervention solutions are based on advanced engineering, clean technology, and a determination to enhance safety. This enables us to reduce environmental risks, fuel consumption and carbon footprints.

In 2010 Welltec® expanded into the Completion side of the industry and designed a metal expandable packer – the Welltec Annular Barrier (WAB®).

The main advantages of the WAB are a reduction in the use of cement for well construction, and minimization of Sustained Casing Pressure (SCP). By tackling these issues, an improved well integrity is delivered that lowers the risk of a dangerous blow-out and removes the need for flaring of harmful gases.

The environmental nature of the benefits delivered by Welltec’s innovative solutions, provides a natural stepping stone for promoting safer and more sustainable types of energy for generations to come...

Building on our deployment track record

We have already started building on our deployment track record by helping geothermal operators overcome a range of challenges.

In one such case (Asia-Pacific), we combined metal expandable packers (WAB) with cementing to help our client achieve isolation and revive a geothermal well, despite highly challenging conditions. The achievements from this operation are providing the foundation for a co-authored academic paper – an abstract has already been submitted.

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

• Geothermal well construction and EGS – Enhanced Geothermal Systems for high temperature power generation
• Rigless Intervention and Urban Intervention – for low temperature direct use applications.

Innovative intervention tools and completion products for renewable energy sector

Traditional Intervention methods tend to be heavier and more labor intensive to set up and carry out. There is now a growing preference for performing complex Well Interventions using more innovative downhole solutions, with electro-hydraulic robotic tools run on an electrical wireline (e-line). 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.
