GEM™ Elemental Analysis Tool
Precise evaluation of complex mineralogies
Offering quick and precise evaluations of complex mineralogies, the Halliburton GEM Elemental Analysis Tool uses proven interpretation processes and integrated petrophysical analysis. A neutron-induced capture gamma ray spectroscopy logging system, the GEM tool is designed to derive elemental contributions contained within the total measured gamma ray energy spectrum.
Identification of critical unconventional “Sweet Spots”
Our innovative technological engineering allows the GEM tool to provide the most precise quantitative understanding of complex carbonates and shales. Improving 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.
The GEM tool also 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. You may now obtain more accurate estimates of your reserves, design optimal completion and stimulation programs, and maximize production.
- Improve accuracy of integrated petrophysical analysis
- Mineral fractions such as gypsum or anhydrite, carbonate, coal, pyrite, salt, siderite, quartz, feldspar, mica and clay from complex formation analyses
- Matrix density values for more accurate porosity calculation
- Sigma matrix for cased and open-hole sigma saturation analysis and improved neutron porosity environmental corrections
- Improves permeability estimates based on mineralogy
- Quick cool-down of eutectic heat sink for rapid job turnaround
- Borehole shielding for reduced sensitivity to borehole fluids
