Since the early 1990s, Liquid Casing Inc. has served the oil and gas industry with its proprietary product line of drilling additives designed to apply the concept of "wedging compressibility of particles" to effectively seal micro-fractures and porous formations. With more than three decades of experience in the field, we understand the many challenges when drilling an oil or gas well and offer environmentally friendly advanced additives that prevent and stop losses while protecting the wellbore from the damaging effects associated with fluid invasion and the invasion of solids.

The Ideal Solution for Protecting The Wellbore
Through its proprietary design and manufacturing process, Liquid Casing Inc. products exhibit the unique characteristic of "wedging" under pressure. When drilling fluid is treated with Liquid Casing, micro-fractures and porous formations are effectively sealed as differential pressures increase. The seal formed by Liquid Casing forms a "compressible wedge", allowing it to plug the surface of the micro-fractures and porous formation without damaging the formation. This "compressible wedge" prevents drilling fluids from invading the micro-fractures and porous formations beyond the surface by creating a seal that can adjust to varying increases and drops in differential pressure without being breached. In this manner, the formation is both reinforced and shielded from harm.
The Liquid Casing Inc. product line has a near 99% return permeability, allowing its proprietary particles to exit the formation and return to the surface when the differential pressure is lowered.

Drill Through Troublesome Geologies, Prevent Losses, and Protect the Wellbore
Liquid Casing Inc. products are used to effectively drill through otherwise troublesome shale sections without damaging the formation. When drilling through these troublesome sections, it is common that inhibition is reduced through the incorporation of suitable shale inhibitors. By using proper inhibitive mud systems, the pressure can be managed by adopting a suitable mud weight.
However, the drilling process results in micro-fractures and voids in the shale. This is due to the pore throats of different shapes and sizes in the shale lattice, which results in predominantly fractured shale. These cracks must be properly reinforced to seal the pores and stabilize the shale; otherwise, sloughing shale will result.
Through its unique characteristic of "wedging" micro-fractures and porous formations, Liquid Casing protects the formation from invasion of the drilling fluid by creating a seal that can adjust to varying increases and drops in pressure without being breached and without damaging the formation.
"Wedging compressibility" results from Liquid Casing Inc.'s proprietary distribution and range of various particle sizes which work together in the drilling mud to form a seal that creates a thin barrier with low-permeability. As these particles interact in the drilling fluid, they are "wedged" into the exterior of the formation where they form a protective barrier to prevent and stop losses while also shielding the formation from damaging fluid invasion.

The Fluid Choice for Maximizing Returns
Through its proprietary method of creating compressibility through the characteristic of "wedging", Liquid Casing Inc. products are specially engineered to mechanically plug the pore throats at the surface of the formation while protecting the wellbore from damaging invasion of fluid and solids. In this manner, Liquid Casing Inc. additives has developed a proven track record worldwide for ensuring unobstructed flow in the pay zone.

What is Liquid Casing?
Liquid Casing Inc. is a polycrystalline material with various particle shapes and sizes which ensures superior performance by inhibiting invasion of the drilling fluid into the formation and thereby protecting the wellbore from damage.
The name Liquid Casing was designed to communicate the principal of "wedging compressibility" by describing the product as a "casing" that forms a hardened seal under pressure, but also is compressible enough that it is able to form a surface plug that bends like liquid. This combination of a hard surface plug that can also compress under treasure without breaching describes the "wedging" phenomenon, whereby particles are packed into the surface of the micro-fractures with increasing differential pressures to form an effective, rubber-like cork seal that shields the formation from fluid invasion.
Our products are biodegradable, non-toxic, and pass all environmental regulations stipulated by various agencies in the Gulf of Mexico, the North Sea, and other environmental regulators.
We offer our drilling additive in three forms: Coarse, Fine, and the R-line. The "Fine" product grade is used in the entire mud system to reinforce the formation as a preventative measure, while the "Coarse" material is used to cure down-hole losses when they occur. The "R" product grade is formulated to address more particular concerns for protecting the reservoir.

Performance Based with Proprietary Manufacturing
Through our many success stories and superior performance, we have elevated the concept of noninvasive or minimally invasive drilling additives in the industry. Our additives prevent and stop losses while protecting the wellbore and reservoir from incurring damage during drilling operations.

An Environmentally Friendly Drilling Additive
When used in the system, Liquid Casing is found in both the external and internal filter cake. Due to its lightweight characteristics and bulk density of 0.70-0.74, the internal filter cake can be as high as 1-2 inches deep in the formation. With this quality and method of activation, the product acts as a rubber-like cork, which seals the pores.
When sufficient drawdown is given while bringing the well to production, the material will come out of the wellbore and can be removed during initial cleanup. As a result, our products are reservoir friendly and degrade slowly with the bacteria present in the down-hole due to its biodegradability.
