The petroleum industry requested a calibrated method to measure the permeability of tight rocks because the usual practice lacked consistency. We designed and built a calibration standard so equipment would give consistent and accurate core sample permeability readings. Typical core diameters are 1” and 1.5”.
Currently, Precision MicroFab™ manufactures various sizes of calibration standards with micrometer-sized channels ranging from 2µm to 50 µm. Some standards have multiple channels. So give us a call and let us know your requirements.
