Abstract: The invention relates to an additive based on a polyalkylene imine and a sulfonated formaldehyde-containing condensation product, and the use thereof as a fluid loss additive for the cementing of boreholes in the fields of crude oil and natural gas. Typical representatives of polyalkylene imines are polyethylene imine, polypropylene imine, and polybutylene imine, which can also be derivatised. Preferred condensation products are acetone/formaldehyde resins. Such additives which are left to ripen before being used, especially by being allowed to stand, have an especially low fluid loss value.

Abstract: An additive based on a polyalkylenimine and a sulphonated formaldehyde-containing condensate and its use as a fluid loss additive in the cementing of wells in the mineral oil and natural gas sector is claimed. Polyethylenimine, polypropylenimine and polybutylenimine are suitable as typical representatives of the polyalkylenimines and may also be derivatised. Preferred condensates are acetone/formaldehyde resins. Those additives according to the invention which are subjected to maturing, in particular by allowing to stand, prior to their use achieve a particularly low fluid loss value.

Abstract: The invention relates to a graft copolymer on the basis of a component a), comprising silica, which has been converted using unsaturated silane, and a sulfonic acid-containing polymer component b). The silica used is preferably nanosilica, and the unsaturated silane is an ethylenically unsaturated alkoxy silane. Component b) is represented by a copolymer on the basis of AMPS and a further ethylenically unsaturated monomer. The polymer according to the invention, which generally constitutes a nanocomposite, is excellently suited as an additive in construction chemistry applications and for the development, extraction and completion of underground crude oil and natural gas deposits, wherein the effect thereof as a water retention agent is particularly advantageous for high salinity and elevated temperatures.
