  • Fluid Loss in cement slurries for oil well applications

    Fluid loss is simply measured in the lab (as per API-RP-10B), (see also Miguel Diaz' article Lab tests to review when designing a "gas tight" cement slurry) where a slurry is mixed and poured into a small cell with a filter medium (325 mesh screen at the bottom). The cell is pressured up to 1000 psi, and then a valve is opened at the bottom and

    Jan 01, 2015· Furthermore, a sulfonate-containing cement dispersant is necessary. The additive can be used in wells with a bottom hole temperature of 80-300 °F (30-150 °C). The fluid loss additive mixture is especially effective at low temperatures, for example, below 100 °F (40 °C) and in sodium silicate-extended slurries.

    Nov 06, 2016· – Start with a high yet low FL control (+/- 250 ml/30min). This can probably be achieved just with cement and dispersant. Sometimes increasing the density 1 or 2 points above neat cement (above 15,8 ppg for class G or 16,2 ppg for class H) helps, e.g., 15,9 or 16 ppg for class G (cement itself is the best FL control additive).
