Halliburton has released the GEM™ Elemental Analysis tool, which offers rapid and precise evaluation of formations with complex mineralogies. As the newest addition to Halliburton's portfolio of formation evaluation technologies, the GEM tool offers operators a complete elemental analysis solution for complex reservoirs and complements Halliburton's existing cuttings evaluation service performed while drilling. When combined with Halliburton's real-time data acquisition software, it offers customers onsite and remote visualization of formation elemental data quickly and accurately.

"The innovative system design allows the GEM tool to provide the most precise quantitative understanding of complex carbonates and shales for our customers," said Jonathan Lewis, vice president of Wireline and Perforating, a Halliburton product service line.

The GEM tool improves the measurements of magnesium in carbonates and aluminum in clays and shale -- until now the most difficult elements to measure but among the most important needed to describe the reservoir. Also available for the first time in the logging industry, the GEM tool measures manganese, a common constituent of carbonates and sheet silicates. Use of these three additional elements -- magnesium, aluminum and manganese -- to determine mineralogy improves estimates of porosity, saturation, permeability, detection of swelling clays and rock mechanical properties. Operators obtain more accurate estimates of their reserves, design optimal completion and stimulation programs, and maximize production.
