InnospeXion X-Ray Systems for Petroleum R&D
 |
2-D
core scanners designed for 1, 1.5, 2 or 4 inch rock drill cores are fast and can
provide a one - or pseudo 2-D result.
Imaging is not an option owing to the cylindrical nature.
However, the systems are cost-effective and classical.

Quantitative Reservoir Rock Studies Using X-Rays
|
The
InnospeXion X-Ray Systems for Petroleum
Research are intended for the quantitative assessment of the 2- or 3-D
studies of the flow of oil, gas or
water in porous reservoir rocks, in order to optimize the oil exploration
possibilities. The
basis of our systems is the use of calibrated,
stable x-ray emission sources, high stability detectors and precision
mechanics. In
addition we offer InnospeXion’s
expertise in x-ray safety and x-ray technology.
This is the solution to precise laboratory tests and 2- and 3-D flow
interpretation. We
offer systems based on x-ray attenuation
measurements and real-time high sensitivity
imaging. Simple
core scanners or 3-D rock slab imaging and measurement systems. |

Three Phase Flow Measurement and Real-Time Visualization |
How it Works
The
3-D X-Ray Core Scanner is based on a low kV x-ray source that emits a narrow
beam of electromagnetic radiation, which is attenuated by the porous rock
sample. Attenuation
depends on the composition and porosity of the sample.
The sample is placed in a slide tray, which is made accurately to fit a
1000 x 1000 mm sample. The
sample holder provides for an auxiliary system that enables flow of a liquid
through the sample, in a direction normal to the x-ray beam.
The
3-D X-Ray Core Scanner incorporates two distinct measurement options (a) the
real-time imaging of the actual attenuation image using a linear array that is
moved across the sample simultaneously
with the x-ray source, and (b) the measurement of attenuation by the rock sample
using a Nal scintillation detector which is moved in steps simultaneously with
the x-ray source. The
first technique provides an image that may be correlated to an actual flow
pattern and flow composition within the sample, whereas the second technique
enables a more accurate assessment of the actual composition of the flow
constituents across the sample.
Precision and Scan Speed
The
3-D X-Ray Core Scanner has been developed for quantitative studies of the
migration of various fluid in the rock sample.
The positional accuracy depends on scanning speed, and the statistical
accuracy depends on the
rock, the thickness and the integration time.
At routine usage, the X-Y position accuracy is about 0.5-1 mm, and the
counting accuracy is about 1-2% for an average count rate of 20,000 cps.
Better
precision is possible at the expense of scan speed.
A total scan at 5 mm resolution of a 1x1m2
rock in counting mode will take about 2502
to
4002
seconds, whereas the complete image scan takes about 5-30 minutes.
