    PVTSIM Nova

PVTsim Nova is a versatile PVT simulation program developed by Calsep for reservoir engineers, flow assurance specialists, PVT lab engineers and process engineers. PVTsim Nova is an upgrade of the PVT simulation package PVTsim.

PVTsim Nova complies to the standards of a modern .NET application ensuring full support from the Microsoft development platform.

PVTsim has been used by leading oil producing and operating companies throughout the world.

Based on an extensive data material collected over a period of more than 30 years, PVTsim Nova carries the information from experimental PVT studies into simulation software in a consistent manner and without losing valuable information on the way.

PVTsim Nova allows reservoir engineers, flow assurance specialists and process engineers to combine reliable fluid characterization procedures with robust and efficient regression algorithms to match fluid properties and experimental data. The fluid parameters may be exported to produce high quality input data for reservoir, pipeline and process simulators.

PVTsim Nova is petroleum phase behavior at the tip of your fingers.

NEW FEATURES AND MODULES IN PVTSIM NOVA 5.0

APPS

  • XML IMPORT
