With speed and ease of use at its core, processes such as fluid and lab data QC, phase envelope generation, flash results and model comparison are automatically performed for any fluid.
Carbone is powered by the technical kernel from IFPEN.
Built as part of KAPPA Generation 6, Carbone has a web UI and separate back end, allowing various deployment configurations, namely stand-alone, client-server, or through the KAPPA-Automate platform as a microservice.
Carbone offers an extensive, customizable and extendable internal database of pure and pseudo components to define a fluid.
The following EoS models are available:
- Peng-Robinson, 1978
- Soave-Redlich-Kwong, 1972
Twu/Edmister, Lee-Kesler Extended, Riazi/Edmister and Pedersen correlations are available to compute pseudo component properties from Mw, S.G and/or Tb.
The Søreide & Whitson, 1992 model is used for 3-phase aqueous flash.
A detailed, multi-sample, field-wide characterization can be carried out in Carbone.
The tuned characterization can help QC any bad quality GC data and systematically replace bad quality GC data with reliable estimates from the model. In the absence of extended GC data, the plus fraction can also be split into heavier fractions from the characterization.
Once a characterization is created, it can be applied to any compatible fluid, allowing users to develop field-wide EOS models.
Carbone offers a wide range of options to QC a given fluid at any stage in the workflow. All QCs are automatically and always performed on all fluids.
Split and Lumping can be done with various options to offer full control of the process.
Wax, Asphalten and Hydrates can be modeled with automatic dedicated split or lumping enabling to characterize solid and non-solid parts
The following conventional experiments can be loaded and simulated:
- Constant Composition Expansion (CCE)
- Constant Volume Depletion (CVD)
- Saturation Pressure
- Saturation Temperature
- Differential Liberation
- Classical Separator
Nine kinds of regression types are available and Two gradient based solvers are available for regression: KAPPA and Hubopt.
Multi-sample Lab Data Management. Flexible lab data management allows users to compare different experiments for a single sample or across multiple samples loaded in a given Carbone document.
Once a common characterization is built for multiple fluids, a global regression can be run on them. Each fluid will use its composition to match its lab data, while maintaining a unique characterization across all the fluids.
Fluids properties can be defined using a broad range of Black Oil correlations (see KAPPA Technical References). These correlations can also be tuned to user data.
The following processes can simulated:
- Separator and Mixer
- Miscibility calculation
- Wellstream Composition Calculation/Adjustment
- Shrinkage calculation
- Compositionnal gradient
Carbone offers the following compositional formats to export fluid PVT:
- XML compositional (for KAPPA applications)
- Eclipse™ compositional
- PROSPER™ compositional
- CMG compositional (GEM™)
- OLGA: EoS CTM, EoS TAB and Wax Table
Black oil tables can be generated for a compositional fluid and exported in one of the following formats:
- KAPPA BO
- Eclipse™ BO and GI
- CMG BO (IMEX™)
