BT-51S Accelerator
Overviews
BT-51S decreases thickening time, increases early strength, and shortens the time wasted at the well site as operators wait for cement properties to take hold. BT-51S can be adjusted to meet specific conditions and requirements. Mixes with low concentrations decrease slurry viscosity, while mixes with higher concentrations increase slurry viscosity. BT-51S is effective at temperatures between －10℃ and 100°C in concentrations of 1% to 4% by weight of cement (bwoc).
BT-51S meet the API requirements applicable to all levels of oil well cement。It is recommended to use with the BITOP series additives.
