摘要
A method for reducing fluid loss from a water-based wellbore servicing fluid is disclosed. The method includes preparing a fluid loss control additive that is substantially stable even at a high temperature of about 350° F. The fluid loss control additive may be formulated by dry mixing of a natural starch and sodium monochloroacetate for a first predetermined reaction time period; spraying an alkaline solution onto the dry mixture for a second predetermined reaction time period to form a complex starch mixture; and treating the complex starch mixture for a third predetermined reaction time period with a diluted cross-linking agent.
