Enhanced Well Solutions

Covia offers a variety of enhanced well solutions including additives, activators and diverting agents.

Enhanced well solutions

From well cementing additives and activators, to gravel packing sands, Covia can provide the solution you need for your unique requirements.

SilverBond
Active at high temperatures, SilverBond® falls between a 275 and 325 mesh, making it more effective. It creates a homogeneous slurry, increases compressive strength and prevents strength retrogression in well temperatures greater than 230°F, all the while improving cement bonding between casing and formation, even under acidic and more importantly thermal expansion/contraction conditions.

Superset W
Activators are liquid chemicals that assist curable resin-coated sand to set (bond) when the downhole temperature is between 100-150° F. Maximized grain-to-grain bonding forms a cross-linked lattice in the fracture that controls proppant flowback, minimizes embedment, and increases conductivity for better well performance.
This activator is time tested in building bond strength in curable resin-coated sand when the well temperature is below 150° F. Recommended application rate is five to ten gallons per 1,000 gallons of frac fluid, depending on desired shut-off time and well temperature. When used with Super LC®, Superset W can achieve unconfined proppant pack compressive strengths of over 400 psi.

BioBalls® water-soluble ball sealers are used as diverting agents for zonal isolation. You can deliver fluids efficiently, allowing you to control the effective time of sealing, diverting, and zonal isolation. Field-proven in vertical and horizontal wells for over 20 years, our ball sealers dissolve in all aqueous fluids.
