FluidView Three-Phase Fluid Saturation Service

Provides three-phase formation fluid saturation analysis in light-oil or high-salinity reservoirs

The Baker Hughes FluidView™ three-phase fluid saturation service provides through-casing quantitative three-phase formation fluid saturation analysis in light-oil or high-salinity reservoirs, helping to resolve ambiguities in traditional cased-hole formation evaluation techniques. The FluidView service combines pulsed-neutron-induced, high resolution gamma-ray data from the Reservoir Performance Monitor™ (RPM™) service, and comprehensive, forward-looking Monte Carlo N-Particle (MCNP) Transport Code modeling database to deliver a transparent quantitative three-phase fluid saturation analysis.

Quantitative saturation
The FluidView service has a highly versatile processing methodology, which uses MCNP modeling and different processing algorithms based on reservoir conditions. In low-salinity formation water and light-oil reservoirs, the FluidView service uses a combination of Inelastic and Capture ratios from multiple detectors; in high-salinity reservoirs, it uses Inelastic or Capture ratio and Sigma measurements to deliver a three-phase saturation solution.

Typically, in a low- or mixed-salinity formation water environment, the carbon/oxygen (C/O) logging mode of a pulsed-neutron instrument is used to obtain salinity-independent water and oil saturation. However, C/O logging cannot be used to determine gas saturation. Under similar formation-water salinity conditions, Sigma logging can deliver only qualitative gas indications, using curve overlay techniques.

Transparent analysis
MCNP modeling provides the capability to generate forward-looking models to predict the response of the curves for varying combinations of mineralogy, formation fluid density, formation gas pressure and density, borehole holdup, and completion configurations. The dynamic curve response envelope algorithm takes into account the variations in porosity, mineralogy, and completions to increase reliability in the measured and processed data.

Efficient acquisition
Data from the following Baker Hughes services can be acquired with the RPM service in the same run:

  • GasView™ gas saturation service
  • OilView™ two-phase fluid saturation service in light-oil reservoirs
  • NEO™ neutron-emulated openhole log service
  • RockView™ Slim basic lithology service
