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.

US: Argonaut Private Equity has acquired a well cement business following the bankruptcy of Texas-based BJ Services. The purchase retains 260 employees and procures company assets and equipment, including bulk plants and technical labs located in the field. No fracturing assets were acquired in the acquisition. It has rebranded the business as American Cementing.

“The addition of American Cementing to the Argonaut Private Equity portfolio combines our expertise in efficient operations management with our experience in the oil and gas industry,” said Steve Mitchell, Argonaut’s chief executive officer (CEO).

American Cementing services include laboratory testing, blending at the bulk plant and mixing and pumping operations at the wellsite. Additionally, the company offers acidising services and products that are intended to enhance production and remove well-bore damage to preserve well lifetime.
