Calsep’s main product is PVTsim Nova, a versatile PVT simulation program developed by Calsep for reservoir engineers, flow assurance specialists, PVT lab engineers, and process engineers.
35 Years of PVT Expertise
Calsep is a leading provider of PVT simulation services to the oil & gas industry. Calsep has solved PVT modeling projects in all continents. The projects involve EoS modeling of all types of reservoir fluids, including natural gas, gas condensates, near critical fluids, black oils and heavy oils.
Calsep’s main product is PVTsim Nova, a versatile PVT simulation program for reservoir engineers, flow assurance specialists, PVT lab engineers, and process engineers.
PVTsim Nova
PVTsim takes you all the way from fluid sample to design and process planning. You can quality check your fluid compositions, develop EoS models, handle water, evaluate the risk of solids precipitation and generate input to more than 30 different external simulators including some of the most widely used reservoir, process and flow simulators.
PVTsim Nova is used by more than 300 companies in the oil and gas industry.
Automated Input of Data
With PVTsim Nova 5.1 Calsep supports PRODML and Calsep Excel PVT Templates, which can be used for importing fluid compositions and PVT data into PVTsim in one click.
EoS Modeling Single Fluids
PVTsim offers an automated development of and equation of state (EoS) model. It enables PVTsim users to develop a high quality EoS model within minutes.
Field Wide EoS Modeling
In PVTsim users can develop EoS models for fluids in communication or fluids that will be commingled and produced through the same pipelines and separation process.
Flow Assurance Features
The polar nature of aqueous components calls for advanced models to accurately simulate the mutual solubility between aqueous and hydrocarbon phases.
Interfaces to Reservoir, Flow Assurance and Process Simulators
The interface modules provide easy export to the most widely used reservoir, flow assurance and process software.
Upgrades & Support
PVTsim maintenance gives access to the latest version of PVTsim Nova and technical support from Calsep’s consultants who are specialized in thermodynamic modeling of all kinds of reservoir fluids.
