DUALFID STAR

DualFidTM Star integrates GEOLOG’s advanced gas detection system measuring hydrocarbons from C6 to Toulene
 
GEOLOG’s DualFidTM Star service identify formation fluid contacts (GOC, OWC) while drilling, thereby maximizing reservoir information in exploration wells and creating interpretative models for hydrocarbon fluids composition (fluid signature) for intra-field correlations and reservoir prediction
EQUIPMENT
A rackmounted, dedicated heavy gases chromatograph (from Hexane to Toluene) integrating the traditional mudlogging C1-C5 analysis.
METHOD  
DualFidTM Star is a new approach to the analysis of heavy gases beyond C5 at rig site. It exploits the reliability and accuracy of FID technology to obtain full and clear separation of heavy components.


 Rackmounted DualFidTM Star:
· Accurate
· Easy to use
· Sturdy & Reliable
ADVANTAGES  
The DualFidTM Star adds to GEOLOG’s gas analysis package two powerful tools: aromatic gas behavior analysis and identification of reservoir fluid signature. This is achieved with:
  • Zero extra deck space required
  • Accurate formation evaluation in near-real time
  • Minimal supervision required
FIELD EXAMPLES

Geolog utilizes and develops dedicated gas ratios for the interpretation of heavy gases behaviour
 
Ternary diagrams amongst the heavy components of the hydrocarbon fluid enable the quick recognition of separate zones within the reservoir
 

Identification of Gas-OilContact and resolution of thin, productive sand stringers possible with DualFidTM Star
