The “PIK-API RP 61” installation is designed for studying operational characteristics of proppant pack in thermobaric conditions corresponding to reservoir or established regulatory documents. The equipment allows evaluating long-term and residual packs conductivity of all types of proppants (ceramic proppants and quartz sands) by performing continuous measurements of compression forces of the pack, its height and liquid permeability at pore pressure up to 5.2 MPa (720 psi) and compression pressure up to 138 MPa (20,000 psi).
The equipment and measurement procedures comply with the standards: GOST-P 51761-2013, ISO 13503-5, API RP-61.
