Lightweight cement slurry
Optimize cement properties for reliable zonal isolation.
The SFM solids fraction monitor determines liquid-solid ratios accurately, independent of slurry density. The system measures the rate of mix water and slurry flow, calculating the solid fraction from those measurements. Adjustments are made to maintain the slurry at the proper water-to-cement ratio. Maintain your desired slurry properties while continuously mixing and pumping large slurry volumes.
The SFM monitor increased success for a Middle East operator. Using the high-solids, low-density LiteCRETE lightweight cement slurry reduced the hydrostatic pressure, and controlling the solids ratio using SFM technology helped place competent slurry to surface.
The team pumped more than 1,200 bbl of 8.7-ppg slurry on the 13 3/8-in surface casing job. The designed solids ratio was maintained. With the proper solids ratio, set properties were excellent. Cement evaluation logs confirmed isolation across the zones of interest.
This operator has used SFM monitor on more than 40 jobs in a year, ensuring better zonal isolation and reduced workover costs.
SFM monitor has become the control method of choice for mixing low-density slurries in the US, Mexico, Europe, Africa, the Middle East, and Indonesia.
