US: SLB has launched EcoShield, a geopolymer-based well cement product. The company, also known as Schlumberger, says that the product cuts out up to 85% of embodied CO₂ emissions compared with conventional well cementing systems because it does not use ordinary Portland cement (OPC). It also reduces transport related emissions by using locally-sourced natural materials and industrial waste streams in its composition. The company says that the cement-free system can be deployed throughout various phases of the well life cycle, including abandonment. It can also be deployed across a range of field applications, including corrosive environments.

Jesus Lamas, SLB’s president of Well Construction, said “Decarbonising the well construction process while ensuring safety and performance standards is critical to our industry’s pathway to net zero.” He added “The cement-free EcoShield system is a breakthrough that delivers industry-standard zonal isolation capabilities while significantly minimising impacts from upstream oil and gas production.”

EcoShield has been tested by Pioneer Natural Resources in the Permian Basin on an 18-well field testing campaign and its use is ongoing.

Europe/North America: Switzerland-based LafargeHolcim and US-based Schlumberger plan to study the feasibility of carbon capture and storage (CCS) systems at two cement plants in Europe and North America. The companies say that the partnership is intended to as a precursor towards the deployment of large-scale CCS solutions.

LafargeHolcim’s chief sustainability officer Magali Anderson said, “Today’s announcement is further proof of LafargeHolcim’s environmental leadership and commitment to pioneer new solutions to reduce carbon emissions on our journey to become a net zero company. Our partnership with Schlumberger, the world’s leading provider of technology to the global energy industry, will bring new advances in storage that could be replicated at scale across our sites.”

France: Vicat has joined US-based Schlumberger New Energy, clean energy specialist CEA, Vinci Construction and the Occitan Regional Agency of Energy and Climate (AREC) in a hydrogen production technology joint venture called Genvia. The partnership will establish a ‘gigafactory’ at which to develop high-temperature reversible solid oxide electrolyser technology. The gigafactory will be situated in Béziers, Occitan. Deployment will take place via CEA’s Grenoble, Auvergne-Rhône-Alpes site.

“We are very pleased to be working alongside such experienced and strong partners as we strive to develop technologies that enable decarbonisation,” said François Jacq, chairman of the CEA. “Together, building on a set of technologies developed by the CEA over the last decade, we have ambitious growth plans for a technology that we expect to be a game-changer in the production of clean hydrogen. This initiative demonstrates an alignment of environmental and economic growth ambitions that is important for France and Europe in support of the government's and the commission's recovery plan.”

The technology Genvia plans to use is intended to achieve a high system efficiency, resulting in less electricity use per kg of hydrogen produced. The venture says that the technology is the first of its kind that is fully reversible, giving it the flexibility to switch between electrolysis and fuel cell functions.
