Tri-D FacsWax™ is a FacsRite™ screen made with Tri-D Weave™ filtration media that has been factory treated with a wax coating to temporarily seal the filter media. The coating allows the sand control liner to be circulated or floated to depth, and prevents the filter media from being plugged while aiding in well clean up.Download Brochure » Contact Us »
The coating is tailored to the formation conditions and temperature. After the well is completed, applying heat or solvents will melt or dissolve the wax coating and open up the filter media for production and/or injection.
Deploying conventional screens into long laterals is difficult due to increased torque and drag, risk of getting stuck, and permanent formation damage. Conventional screens generally lack the strength to push/rotate past tight sections. Adding a washpipe with seal assemblies to allow circulation through tight sections and cleanup of formation damage increases torque and drag, as well as rig time and completion costs.
Semi-consolidated or unconsolidated formations require aggressive drilling muds to prevent formation collapse but such muds plug conventional sand control screens.
Sealing Tri-D FacsRite disks with wax allows the screen to be either circulated without a washpipe or floated to depth, thus reducing torque and drag. This is an important consideration for extended reach wells. The enhanced strength of Tri-D FacsRite allows additional pushing/rotation to get past tight sections.
Mud conditioning requirements are reduced because the disks are protected. After reaching TD the mud can be recovered for reuse and replaced with a completion fluid to minimize formation damage, making startup easier and quicker.

FacsWax builds on the proven sand control capability of FacsRite and Tri-D FacsRite™ to simplify liner deployment and well clean-up for the following applications:
FacsWax gives operators a high performance sand control liner and the ability to:
Heat or solvent soluble paraffin treatment can be applied to disks made with premium weave, or disks made of Tri-D Weave filtration media.
As well, both Tri-D FacsRite and FacsRite can be tailored for open flow area and liner strength by varying the size of the disks and number of disks per foot of liner.
Absolute began early tests for applying a wax coating to sand control screen with standard FacsRite in 2011. FacsRite screens filter discs made of conventional premium square or Dutch weave media flush mounted into base pipe. The result is a fullbore screen with optimum ID/OD that can be tailored to formation potential and cost by selecting the size, and distribution density of the discs. The factory applied wax process proved to simplify liner deployment and well clean-up and prevented the filter media from being plugged during deployment.
Absolute has further developed the patent pending WaxRite process for a variety of screen types including Tri-D FacsWax, SlotWax, MeshWax and AccuWax.
