Core Lab has the capability of chemically saturating different sizes of proppant
on a custom basis and drying the saturated proppant at various temperatures on a
large-scale volume. The proppant is then placed in a rotating dryer and dried at
a specified temperature and time. Moisture content can be measured for quality control
purposes to ensure it meets customer standards.
Particle size and distribution can be measured by means of a Malvern Mastersizer.
Particulate size can range from 0.05 µm to 900 µm. The particulate can either be
in the form of dry solids or suspended in a solution of water based or oil based
mud. An integrated computer software package generates tables including mesh size,
aperture size, percent particle volume, and percent volume below which solids passes
through a particular mesh size.
