FLAIR Real-time Fluid Logging and Analysis Service

Quantitative assessment of formation hydrocarbon composition

FLAIR real-time fluid logging and analysis service is a premium gas service focused on fluid facies characterization and early information about formation fluid composition. Hydrocarbons extracted from the drilling mud returns at surface are continuously analyzed to provide a unique quantitative analysis of C1–C5 that is analogous to the downhole formation fluid. In addition, qualitative information on the C6–C8 components, including methylcyclohexane and light aromatics (benzene and toluene), improves fluid characterization.

FLAIR analysis service has been conducted in almost all operational and geological environments, the results unaffected by drilling conditions such as deepwater wells, cold mud returns, and complex modern drilling fluids.

Daily fluid facies log to assist reservoir appraisal

A fluid facies log is generated daily, providing information for

  • analyzing fluid similarities and dissimilarities
  • characterizing cap rocks and reservoirs
  • delineating pay zones
  • determining the composition of formation hydrocarbons
  • locating fluid contacts
  • identifying compositional gradients in the reservoir
  • detecting geochemical alteration
  • studying reservoir compartmentalization and connectivity
  • performing well-to-well correlation.

Multiple benefits of early fluid identification FLAIR analysis should be considered complementary to standard fluid analysis. The accuracy of the C1–C5 results has been confirmed by their close correlation with PVT data. This early quantitative assessment of the composition of potential pay zones is providing operators guidance for critical decisions; enhancing geosteering; and helping to optimize logging, pressure testing, and sampling programs. The C6–C8 measurements improve the likelihood of identifying pay zones with low levels of C1–C5. The Extraction efficiency calibration with calibration mud (EECcm) test enables the real-time quantification of C1–C6 hydrocarbons in formation fluid by effectively calibrating mud-gas extraction efficiency at the rig site. In HPHT and other hostile downhole environments, these surface measurements may be the only viable option.
