Description
The conductivity cell is built as per the ISO 13503-5 and API RP 56 & 58 standards. The cell mainly comprises width slats, platens and Ohio sandstone slabs. Three pressure taps permit longitudinal pressure monitoring across the proppant pack. The steel platens are heated by electrical cartridges to ensure isothermal conditions and regulation is governed via a dedicated port, by an in-vessel thermocouple. A thermal insulation mantle is also provided. Four LVDTs (Linear Variable Differential Transformer) are mounted at each side of the API conductivity cell to measure the proppant pack width at different closure stresses.
