Fracture conductivity system Reservoir stimulation Matrix acidizing Instruments

The Fracture conductivity system Reservoir stimulation Matrix acidizing Instruments perfectly determines both short-term and long-term fracture conductivities under realistic down-hole conditions of stress, temperature and fluid flow. The results help in understanding the relationship between temperature, fracture closure stress, proppant concentration and type, proppant embedment, and fracturing fluid composition with fracture conductivity.

Conductivity tests can be performed using either brine or nitrogen. The standard system encompasses an injection pump, two brine accumulators, an inline heater, a heated fracture conductivity cell, a hydraulic press, pressure and differential pressure transducers, a nitrogen gas flow line, two back-pressure regulators, two electronic balances, valves, associated plumbing and a data acquisition computer station.
