Different types of bases for setting balanced cement plugs
Balanced cement plugs which are set off-bottom have been used for decades in the oil and gas industry.
To balance the heavy cement on top of lighter fluids have proved to be very challenging:
- The cement plug is rarely found at its desired depth
- Cement slurry gets contaminated
This paper will provide an overview of the different types of bases used to enhance success:
- Three different types of fluids
- Three different mechanical bases for the cement
There are substantial technical differences between these six types of bases, which we describe in this white paper.
