Conductivity
Conductivity Testing:
Past research has shown as little as 5% fines may
reduce flow capacity by at least 50% via a change in
median particle diameter (MPD). However, this is
just one of several damaging mechanisms (e.g.
polymer residue, fines migration, embedment, cyclic
loading, etc.) that can harm proppant pack flow
capacity.
To better understand and address issues that can
impact fracturing results PropTester®,
Inc. at our Cypress, TX research laboratory
evaluates your supply chain proppant choices with
industry standard (ISO TC/67 13503-5), reservoir
specific, and regained / retained conductivity
procedures.
ISO conductivity testing is a quality control
procedure that permits comparison of proppants under
a standardized set of conditions. A PS-50® test
provides answers to proppant flow capacity at your
specific reservoir pressure and temperature
environment. Regained / retained propped fracture
conductivity measures the impact of fracturing fluid
on the proppant pack performance. Any quarried
sandstone, limestone or downhole core can also be
shaped by an automated surface grinder to simulate
formation material in these conductivity tests.
You specify your testing parameters, up to
20,000-psi stress and 500°F, and proppants screened
for initial consideration. PropTester®,
Inc. will then work with you to reveal and
finalize those products that best meet the needs of
your specific fracturing application.
