PDQ-XRF® and RockEye® Integrated
FIT Geochemical Data Previewer
A unique approach placing the entire well bore history on one viewer that includes:
- • Fluid Inclusion Stratigraphy (FIS) analysis of trapped fluid in cuttings, core or outcrop samples
- • X-Ray Fluorescence (PDQ-XRF®) provides a continuous elemental analysis
- • High Resolution Photography (RockEye®) in both UV & white light
- • Mass Spectrometry Well Gas Analyzer (Dq1000®) log done at the time of drilling

Benefits of FIT "One Viewer" Approach
- • The same sample of rock is analyzed at each step, preserving the interrelationships among rock type, rock chemistry and fluid type
- • The analysis is conducted on the entire bore hole from first returns to TD
- • Lithology profiles in the absence of, or in place of, well site lithology descriptions
- • Distribution and relative abundance of cements
- • Cuttings volatile analysis for hydrocarbons and non-hydrocarbons
- • Chemical stratigraphy for correlation in monotonous vertical or horizontal sections
- • Depositional environment, facies, provenance
- • High resolution photography in both white light and under UV excitation
- • Elemental analysis of rock material via X-ray Fluorescence
- • Rock behavior relevant to completion (e.g., siliceous vs. clay rich)
Key Strengths
- • Process is automated
- • Small sample requirements: 2-5 g washed
- • All analyses are conducted on the same sample with up to 575 samples per well
- • Fast response - analytical cycle of four days from preparation (washing, loading, etc.)
