NEWS FROM SPE ATCE 2013 Halliburton introduces new downhole fluid analysis technology
NEW ORLEANS, La. -- Halliburton introduced its Integrated Computational Element (ICE Core) fluid analysis service today at the Society of Petroleum Engineers Annual Technical Conference and Exhibition.
Previously, optical analyzers could tell an operator when a sample was pure enough to collect, but rarely could they tell them which fluid components were present and in what proportions. ICE Core fluid analysis technology, which is a component of Halliburton’s proven Reservoir Description Tool (RDT tester), delivers this information.
Halliburton’s new technology is well suited for downhole fluid analysis, including applications in deep water, exploration, sample validation, fluid analysis between samples, where flow assurance is an issue, when mapping water floods, when determining reservoir connectivity, when determining compositional grading of reservoir fluids, and to see if fluids are changing.
ICE Core technology works via light shining through downhole fluids and then through ICE Core sensors. Each sensor is programmed to recognize the chemical nature – or optical fingerprint – of a specific fluid component, such as methane, ethane, propane, aromatics, saturates or water.
Measuring the intensity of light passing through any one sensor indicates the presence and proportion of a particular chemical component within the overall fluid.
Unlike other systems, ICE Core technology relies on the ruggedness and simplicity of photometric detection, not spectroscopy. As a result, ICE Core technology does not require a computer to perform calculations on an optical spectrum. Each sensor is designed to respond specifically to the fingerprint of the selected analyte, using all of the useful information in the optical spectrum.
