Liquid Casing® Fine

1 of 2 products in this brand
Liquid Casing® Fine is a microcrystalline product processed to produce a seepage and loss circulation material that can be used in both water and oil-based muds. The key feature of this product is the wide range of particle sizes it offers, ranging from 1-500 microns with a median size of 60-170 microns. The particle size variety ensures that all fractures or pore throats are sealed so the product can move through any configuration of drilling or coring string. It can be added to the mud or completion brine and can be used in the circulating system.

    How It Works

    This high-quality product is manufactured through a unique mechanical process. It is pressed into the pore spaces by the application of pressure to the calculated Equivalent Circulating Density (ECD). The fluid loss function of a drilling fluid additive further enhances the seal that is formed. As a result, the migration of formation damaging fines from wellbore fluids is virtually eliminated.

    Reversal of the pressure, as when the well is brought on-stream, releases the filter-cake off easily as a result of the high-pressure gradient generated due to limited filtrate invasion. This quality ensures rapid clean up while minimizing formation damage. The fine size and relatively large surface area can be exploited to provide a means for chemically removing the particles from the formation.

    Usage
    • Use in whole mud system with 3-4 ppb concentration. If it is oil or synthetic-based mud, it is recommended to use 5-6 ppb.
    • Use coarser shaker screens of no more than 100 mesh size. This will allow the product to remain in the system without passing through the shaker screens. Optimum utilization of centrifuge is recommended.
    • Due to its lightweight (bulk density of 0.74), Liquid Casing will remain in the center of the centrifuge and only a minimum amount of the product will go with the solid phase of the centrifuge.
    • As this product is consumed in the well, to the external and internal filter cakes, periodical additions of the product are required while drilling. A good rule of thumb is to add 2 sacks of Liquid Casing Fine for every 100 ft. (or 30 m) to any new hole drilled.
    • Keep biocide in the entire system.
    • Spot a 50-100 bbl pill at the bottom prior to tripping out. 50 bbl pill is sufficient for an 8½” hole and a 75-100 bbl pill is required for 12¼” to 17½” holes.
