SAC-series Multi stack API conductivity cell

ISO 13503-5, API 61 & 19D


The conductivity cell is fabricated in adherence to ISO 13503-5 and API RP 61 & 19D protocols. Designed for vertical stacking, these multi-stack API Conductivity Cells enable concurrent testing of multiple proppant conductivities. Engineered for shared piston operation, these cells ensure uniform distribution of compressive stresses. Pressure drop across the cell can be monitored through three side ports, each fitted with high-accuracy differential pressure transducers. Components include width slats, O-rings, stainless steel platens, and Ohio sandstone slabs. Isothermal conditions within the cells are maintained by electrical cartridge heaters embedded in the steel platens. Temperature regulation is achieved through a specialized port connected to an in-vessel thermocouple. Additionally, a thermal insulation mantle is incorporated. For real-time measurement of the proppant pack width under varying closure stresses, Linear Variable Differential Transformers (LVDTs) are affixed to each lateral face of the API conductivity cell.
