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.

GEM Elemental Analysis Tool

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.

Benifits

  • Improves accuracy of integrated petrophysical analysis

  • Precisely estimates mineral fractions, such as gypsum or anhydrite, carbonate, coal, pyrite, salt, siderite, quartz, feldspar, mica, and clay from complex formation analysis

  • Provides matrix-density values for more accurate porosity calculation

  • Estimates accurate photoelectric absorption (Pe) from GEM elemental data in wells drilled with heavy mud (barite) where conventional Pe measurement is not possible from density tools

  • Improves permeability estimates based on mineralogy

  • Offers a quick cool down of the eutectic heat sink for rapid job turnaround

  • Allows direct comparision of XRF elemental data from Ingrain*

  • Calibrates mineral model using XRD/FTIR data from Ingrain*
