About CHEM-O-TEC
CHEM-O-TEC GmbH in Hambühren near Celle specialises in toll manufacturing and the production of chemical additives for well cementing and stimulation. The company produces liquid and solid products such as defoamers, retarders, accelerators, viscosifiers, lubricants, gas migration blockers and lost circulation materials to customer formulations – primarily for the oil and gas industry as well as geothermal energy, including HTHP and extended-reach applications. In addition to its own production, CHEM-O-TEC offers mixing and heating of water- or oil-based liquids in glass-coated mixing tanks, dry blending of solids as well as repacking of customer-supplied raw materials (except hazardous goods). Filling is carried out in 25-kg bags, canisters, big bags, drums and IBCs, from prototype to large series in small to medium batches. An in-house laboratory tests every batch, and the company is certified to DIN EN ISO 9001:2015. Worldwide shipping is handled from the 13,000 m² site north-east of Hanover.
