Abstract

The effects of varying concentration of Acrylamide copolymer (an effective fluid loss control additive) and temperature on fluid loss in oil well cementing was studied. The fluid loss of neat cement (Dyckerhoff Class G), fluid loss property of cement slurry with varying concentration of acrylamide copolymer, and effects of temperature in cement slurry with acrylamide copolymer were investigated at temperature range of 48-82oC bottom hole circulating temperature and pressure of 3500 psi. The concentrations of the copolymer studied were 0.25, 0.50 and 0.75 percentage by weight of cement. Thickening time tests were also carried out. The fluid loss value decreased with increase in concentration of acrylamide irrespective of the temperature. At low concentration of the additive, the activity of the copolymer as a fluid loss additive was influenced by temperature. The findings from the research show that fluid loss of cement with the copolymer is a function of temperature and concentration of the copolymer.
