WHOLEPERM-Multi full-diameter steady state gas permeameter


The Wholeperm instrument is dedicated to measuring both horizontal and vertical permeability to gas of full diameter core samples at room conditions. This apparatus can provide enlightening results in the context of heterogeneous, anisotropic rock studies. The unit consists of a base unit with a hydraulic ram and up to four core holders, each designed for a specific range of diameters to be used separately with a maximum length up to 12 inches. Each core holder consists of an outer body and an inner mandrill and sleeve capable of taking core samples in the specified diameter ranges. Standard diameter ranges available for the outer body are for 2 to 2 7/8 inch, 3 to 3 7/8 inch, 4 to 4 7/8 inch and 5 to 5 7/8 inch core samples. The wholeperm is provided with a gas permeameter console and data acquisition computer station.
