Excellence Logging utilizes a variety of technologies to ensure the absolute best quality deliverables. We understand your need for the most customizable service offerings when it comes to mud logging, geosteering and wellsite geology, which is why we offer all of the following technologies:

The Bloodhound by iBall Instruments

  • Non-dispersive Infrared Sensor with detection of C1 – nC4
  • Accuracy ± 3% from 0 to 10,000 gas units
  • Reads up to 5% CO2
  • Reads up to 500 PPM H2S (though it should not be used as the rig’s primary H2S detector)

Flame Ionization Detector (FID)

  • Proprietary equipment detects C1 – C5

Pason Gas Analyzer

  • On-demand, real-time gas chromatograph
  • One-second sampling of C1 – nC5 (nC4 – nC5 reported as C4)
  • Detects and reports CO2
  • Automatically plots wetness, balance, and character ratios
  • Must have a Pason EDR on the rig

The DQ1000 by Fluid Inclusion Technologies

  • Mass Spectrometer
  • Analyzes a range of petroleum species and other organic and inorganic compounds
  • C1-C10 petroleum species; standard gas ratios
  • BTEX compounds & organic acids
  • Inorganics including N2, Ar, O2, H2O, CO2, He, and H2
  • Sulfur bearing compounds including SO2, COS, and CS2


  • The new standard for generating cutting descriptions and reporting well lithology

Custom Logs

  • Each log is customized based on the type of drilling and customer preferences

Our Geochemical Solutions

X-Ray Fluorescence

  • Analysis of major & trace elements in geological materials using the Spectroscout ED-XRF benchtop device

X-Ray Diffraction

  • Analysis of Sand/Silt & clay-size fractions, rocks or sediment using the Olympus BTX II XRD benchtop device

RockEval/Source Rock Analysis

  • RockEval II Pyrolysis, including: S1, S2, S3, HI, OI, Tmax

Total Organic Carbon

  • Measures both total carbon & inorganic carbon present in samples
  • The following are provided for each sample and represented in Van-Krevelen diagrams:
    • Total Organic Carbon – TOC(%), Free Hydrocarbons – S1 (mg HC/gm rock)
    • Generatable hydrocarbons – S2 (mg HC/gm rock)
    • Total Hydrocarbon Generation Potential – S1 + S2 (mg HC/gm rock)
    • Hydrogen Enrichment Index – HI (mg HC/gm TOC)
    • Generatable carbon dioxide – S3 (mg CO2/gm rock)
    • Oxygen enrichment index – OI (mg CO2/gm TOC)
    • Transformation ratio – TR (S1/S1 + S2)
    • Temperature of Peak S2 – Tmax (°C)
