Abstract (en)
[origin: WO2011104061A1] The inventive water retention agents are outstandingly suitable as additives in construction chemical systems, and in the development, exploitation and completion of underground mineral oil and natural gas deposits, and in deep wells, the action thereof being particularly advantageous at elevated temperatures and due to their lack of influence on the rheological properties of the borehole muds.
