Description
The PCM-1000 is a specialized system engineered for assessing the performance of proppants in hydraulic fracturing enhancement projects. Specifically, the device measures short-term proppant pack conductivity under a range of closure pressures and temperature conditions. The experimental procedure involves the controlled displacement of a thermally regulated reservoir fluid through a compressed proppant pack. This pack is sandwiched between two parallel, flat, and identical sandstone slabs. Both differential pressure and fluid flow rate across the proppant pack are meticulously recorded during this process. Utilizing the collected data in conjunction with Darcy's law allows for the precise calculation of proppant conductivity. The sandstone slabs, which are actuated by a hydraulic press, apply a closure stress to simulate the compressive stress conditions experienced within the reservoir rock.
