- How It Works
This product line has an increased particle size distribution compared to our Liquid Casing Fine product. As a result, it interlocks and swells in the fluids to form an effective seal during the drilling process, which increases in efficiency as the pressure increases.
- Usage
- It is normally used to cure losses when moderate to total losses occur.
- The optimum dosage of the pill is 40-60 ppb in the existing drilling fluid.
- In a non-aqueous fluid system, diesel-based or synthetic oil-based, the maximum allowable dosage of Liquid Casing® Coarse is 40 ppb.
- In a bentonite-based water-based fluid system, the maximum allowable dosage is 50 ppb to 60 ppb.
- In a Polymer, XC-Polymer based, fluid system, the maximum allowable dosage is 60 ppb.
- It can be pumped into the bit and BHA, with MWD tools, at the bottom without any problems or any necessary trips.
- The pill volume should be 100-150 bbl depending on the size of the hole and the severity of the losses. Sometimes, one pill, 150 bbl, may not bring complete returns and an additional pill may be required.
