The Proppant Fracture Conductivity Evaluation System is designed to determine the fracture conductivity or permeability of a
proppant pack under downhole conditions in the laboratory. Tests are conducted at a closure stress to 20,000 psi and a temperature
to 3507°F along with brine and/or gas flow as required. It can determine the long-term conductivity as a function of the proppant,
fracturing fluid system and the produced hydrocarbon type/rate. The system has an option for a system to determine the beta turbulence
factor used for predicting gas flow rate, the impact of stress cycling, the amount of embedment in field cores from a variety of proppants,
and the effectiveness of proppant flow back systems. The system is easy to run and very reliable.
