Schlumberger, one of the Park’s companies, receives ANP innovation award

With its research Center located at the UFRJ Science Park, Schlumberger was one of the companies which received the ANP 2016 Technological Innovation Award. This award belongs to the category III – Technological Innovation developed in Brazil by a large company from the Oil, Natural Gas and Biofuels Segment in cooperation with an Oil Company. The winning Project consists of the development of cement paste for cementing operations, drain plug and squeeze of oil wells, which ensure appropriate security in a CO2 environment. The increase on the guarantee of the well integrity when CO2 is present – in the reservoir or injected into the well for secondary  restoration – is a result of fissures sealing and/or micro-anulars in the  cement solidified by the contact with CO2, which would trigger the self-repairing effect  in the cement itself. The technology can be used for cementing wells in reservoirs naturally containing CO2 associated to the formation fluids, as it is the case of the “pre-salt” wells in Brazil, or in those wells in which CO2 is injected, stored or extracted.
