The FCM-1000 is adept at accurately determining both short-term and long-term fracture conductivities under realistic down-hole conditions, including stress, temperature, and fluid flow. This enables a comprehensive understanding of how variables such as temperature, fracture closure stress, proppant type and concentration, proppant embedment, and fracturing fluid composition interact to influence fracture conductivity. Conductivity assessments can be conducted using either brine or nitrogen as the testing fluid. The standard configuration of the system includes an injection pump, dual brine accumulators, an inline heater, a heated fracture conductivity cell, a hydraulic press, pressure and differential pressure transducers, a nitrogen gas flow line, a pair of back-pressure regulators, dual electronic balances, an array of valves and plumbing fixtures, as well as a dedicated data acquisition computer station.
