Carbone

Carbone is a highly interactive package designed to build, tune and operate on EoS or Black Oil fluid models. Whilst the simplest use case may be to build a PVT model for any Black Oil or Compositional modeling platform, Carbone is designed to be used for more advanced applications in reservoir, production and flow assurance domains. These include constructing a field or asset scale unified EoS model, wax, asphaltene and hydrate studies, compositional gradient calculations, fluid separation and mixing, miscibility pressure calculations and simple process system modeling and optimization.

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.

Compositional Fluid Modeling

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.

Fluid QC & Characterization

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.

Solid Modeling

Wax, Asphalten and Hydrates can be modeled with automatic dedicated split or lumping enabling to characterize solid and non-solid parts

Lab Data Input & QC

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
Swelling

Regression Types & Variables

Nine kinds of regression types are available and Two gradient based solvers are available for regression: KAPPA and Hubopt.

Unified EoS

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.

Black Oil 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.

Additionnal Processes

The following processes can simulated:

Decontamination
Separator and Mixer
Miscibility calculation
Wellstream Composition Calculation/Adjustment
Shrinkage calculation
Compositionnal gradient

Export Compositional Fluid

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™)
