Conductivity (md-ft)
A variety of variables influence fracture flow
capacity, which directly relates to well
production. Among these factors are
proppant pack conductivity, cyclic loading,
proppant flowback control, fines migration,
and embedment. XRT Ceramax provides
optimized performance relative to each of
these factors, creating the highest fracture
flow capacity in the industry.

XRT Ceramax’s superior resin technology
eliminates proppant flowback, allowing you
to flow the well back more aggressively than
with other curable proppants in the industry.
The flexibility of the resin system allows the
consolidated pack to maintain its integrity
even after multiple well shut-ins which put
cyclic stress on the proppant pack.
Proppant Flowback Control Comparison
Cyclic Stress
Wells undergo varying degrees of repetitive
stress during their lifetimes. These cyclic
stress changes have the most significant
impact on fracture flow capacity. As the
number of cycles increase, the proppant
pack permeability and fracture width
decrease over time.
Cyclic stress can break a conventional pack,
compromising the integrity of the structure
and reducing conductivity. XRT Ceramax
remains flexible in HPHT environments. In
addition, the XRT Ceramax proppant pack
has the ability to re-heal, eliminating
proppant flowback and fines generation.

Bond Strength (psi)
Whether the proppant is exposed to
downhole conditions or sitting in storage,
temperature stability is an important factor.
The resin coating of typical proppants
begins to cure at elevated temperatures. A
decrease in the amount of curability equals
a decrease in bond strength. XRT Ceramax
was designed to retain its curability at
elevated temperatures and will only bond
when subjected to both high temperature
and closure stress. XRT Ceramax retains
greater than 95% of its initial bond strength
after sitting in storage conditions of 140°F
for 28 days.

The Oilfield Technology
Group (OTG) of Hexion™ is
committed to developing
technologies that enhance the
industry’s ability to stimulate
hydraulic fracturing treatments
and provide improved results.
As more high-pressure,
high-temperature (HPHT)
wells are drilled, the use of
ceramic fracturing proppants
has become commonplace.
Uncoated ceramics encounter
serious performance issues
when exposed to these
harsh well conditions. These
deficiencies include lower
fracture flow capacity due
to proppant fines generation
and migration, abrasive
proppant flowback (causing
possible equipment damage
and well shut-in), and a
reduction in proppant pack
strength from cyclic stress
changes that occur during
the life of the well.
Conventional resin coated
ceramics are designed
to address these issues;
however they fail to perform
under elevated pressure,
temperature, and extended
pump times.
Hexion developed its
patented XRT™ (Extreme
Resin Technology) product
line to perform under the
harshest high-stress, hightemperature well conditions.
Since its introduction in 2003,
XRT Ceramax has been
successfully utilized in
thousand’s of wells around
the world.

The Proppant for Extreme Conditions
Helps You Get The Results You Expect.
SM
A South Texas operator experienced
severe proppant flowback and
disappointing production results
after pumping both conventional
resin coated proppants and “on-thefly” liquid resin systems. This caused
the operator to keep flowback
equipment onsite to reduce damage
to surface production equipment.
It also led to costly wellbore clean
outs with coiled tubing. Switching
to XRT ceramics has eliminated
proppant flowback and provided
increased production results from
these HPHT wells.
Case History: Faster Load
Recovery/Quicker Sales
A North Louisiana operator decided
to use XRT Ceramax E for their
well. After the stimulation job, the
personnel responsible for flowback
noticed that they could flow the well
much faster and still not have any
proppant flowback issues. This
ultimately led to a 10% reduction
in load recovery time, leading to
quicker online gas sales. Since
then, the operator has requested
XRT Ceramax E on all similar frac
treatments in the field; now getting
improved frac cleanup and quicker
ROI from the frac treatments.

Increase Cash Flow with
XRT Ceramax Proppants
During a well’s lifetime, XRT
Ceramax proppants provide
increased cash flow compared
to uncoated ceramics. This is
accomplished in two ways; first,
the higher fracture flow capacity
from XRT Ceramax yields
increased post treatment
production; second, using XRT
ceramic proppants with excellent
proppant flowback control (even
under extreme HPHT conditions)
allows operators to flow wells
more aggressively. This benefit
eliminates concern of proppant
flowback (especially abrasive
ceramics) and the resulting loss
of wellbore conductivity or
damage to surface equipment.
