Improved fluid loss control additives for use in cement compositions are
provided. The improved fluid loss control additives and cement
compositions are suitable for use in surface and subterranean
applications. The improved fluid loss control additives and cement
compositions may be particularly useful for subterranean well completion
and remedial operations, such as primary cementing, e.g., cementing
casings and liners in well bores, including those in production wells,
which include multi-lateral subterranean wells. They also may be useful
for surface cementing operations, including construction cementing
operations. Examples of compositions include fluid loss control
additives.
