SCALEGUARD proppant-delivered scale inhibition treatment

SCALEGUARD proppant-delivered scale-inhibiting technology is a porous ceramic proppant engineered with an innovative controlled release technology and infused with scale-inhibiting chemicals.

Long-term protection from a single application

SCALEGUARD technology is placed throughout the entire fracture as part of the standard fracturing process. A single treatment can be designed to safeguard the entire production system—from the fracture through the wellbore to the surface processing equipment—or the life of the well.

Maintains inhibitors levels

Our unique controlled release technology ensures that scale-generating water is inhibited at a designed rate so that levels remain above the minimum inhibitor concentration (MIC) determined for each application.

Reduce production maintenance costs

Each SCALEGUARD treatment can be engineered to last for the effective life of the well based on anticipated production profiles. The technology significantly reduces production maintenance requirements and costs, avoid workovers and eliminate the potential for catastrophic production system failures. The technology has saved one operator in the Uinta over $160,000 per well in maintenance costs per year.
 
SCALEGUARD technology compared to other scale treatmentsNo loss of conductivity or integrity

SCALEGUARD technology serves as both a scale inhibitor and proppant that has no impact on fracture conductivity. It does not compromise proppant pack conductivity, nor create excessive fines that restrict or block hydrocarbon flow spaces: a risk associated with lower strength particulate-based carriers.

SCALEGUARD no negative impact on propped fracture conductivity

Features
  • Ceramic proppant infused with scale-inhibiting chemicals
  • Controlled release technology provides a significant reduction in chemical wash out
  • Engineered, uniformly distributed, interconnected porosity maintains the critical proppant strength and conductivity
  • Designed placement within the fracture for optimal treatment
  • SCALEGUARD technology stays in place within the fracture to deliver long-term protection from scale build-up
  • May be premixed or added onsite with sand or CARBO ceramic proppant
Benefits
  • Long-term protection from scale build-up
  • Increased long-term production compared to current treatments
  • Simple deployment while you frac with no conductivity impairment
  • Proven technology eliminates costly remediation treatments and equipment failures
  • Both proppant and scale inhibitor reduce operating costs and increase production over the life of the well

A superior alternative

SCALEGUARD technology is superior to other methods of inhibiting scale.

  • Controlled release technology significantly lengthens treatment life and reduces initial inhibitor washout
  • Engineered ceramic proppant that provides effective chemical delivery, high fracture conductivity and strength
  • Liquid inhibitor added to frac fluid is short-lived and inefficient due to the large volume of chemicals required
  • Periodic squeezes are short-lived and must be routinely repeated, incurring ongoing operational expenditure
  • Other particulate chemical carriers added during frac can impair conductivity and inhibitor effectiveness can be short-lived
