Experience All The Effective And Efficient Quality Drilling Products

Our Selection of High-Quality Drilling Additives

Our product line of high-performance drilling fluids is known worldwide as the industry standard in the oil and gas field. We offer a selection of different products that are specially formulated for a wide range of applications.

Liquid Casing® Fine

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.

Liquid Casing® Coarse

Liquid Casing Coarse is a severe loss circulation additive that can be used in oil or water-based muds. The material passes through a ¼” (6,350 microns) dry screen and will not block the jets of the bits or mud motors. This product provides excellent loss circulation control without damaging rheology in all conventional drilling fluids. It is non-damaging and can be pumped through most sizes of bit nozzles without blocking.

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.

Liquid Casing® II

This product is designed to cure losses in the reservoir section where pores are large. It was formulated after extensively studying sandstone and limestone reservoir cores with various pore throats of large and varying sizes. As a result of its design, the product is suitable for use in virtually any reservoir.

Liquid Casing II is particularly useful when the well is brought into production, as the material from the reservoir will automatically come out during initial well cleanup, preventing damage to the reservoir.

The procedures for using Liquid Casing® II are more specialized. A general application has been provided in the following section entitled “Various Liquid Casing® Applications and Treatments.”

How It Works

The wide particle size range and shapes are designed to seal virtually any depleted reservoir or fractures in the structure.

W.Ο. 1000®

W.O. 1000 is a work/over completion fluid additive, which enables the drilling fluid to seal the perforations and halt fluid invasion. This product eliminates formation damage and substantially reduces idle time by 50%.

Usage

In high-pressure wells, before the well-killing operations begin, pump a 20 bbl pill across the perforations.
