Linear X-Ray Saturation Scanner

The Linear X-Ray Saturation Scanner, model CT-ISS-LXR, measures the fluid saturation profile along a core plug while it is being flooded, so that fluid distribution inside the core is known during the test and not only at the endpoints. An X-ray source traverses a pressurized core holder and the attenuation at each position is converted to local saturation for single-phase and multiphase samples. It is used for relative permeability and displacement studies and can be coupled to any Coretest flow recirculation system.

How it works

The core holder accepts 1.5 in. diameter plugs of 4 to 12 in. length (other sizes on request) at confining and pore pressures up to 700 bar (10,000 psi) and working temperatures up to 150 °C, with a homogeneous temperature control system around the holder. The X-ray source is rated 90 kV, 4 mA. The scanner steps along the core under automatic control; the controlled variables are scan position and integration, and the measured variable is the saturation profile along the core. Single-energy and dual-energy scanning modes are available. The holder can be mounted horizontally or vertically to study heterogeneity, anisotropy and gravity effects.

The source and core holder sit inside a thick stainless steel enclosure that isolates X-ray radiation from the operator. Power is 220 VAC, 50/60 Hz; instrument air at 7 bar (100 psi) is required.
