From the File menu choose Create New Database , then save the database wherever you want As can be seen from the right hand plot in Figure 3, EoS 2 provides as almost perfect match of the liquid dropout curves of the swollen mixtures. High simulation accuracy with regression feature.

PVTsim Nova – Calsep

All the reports and drawings can be saved and output as other format. PVT data and simulation of reservoir experiments. Critical point of pvtsimm fluid. With EoS 1 too much gas is to be added before a critical composition is reached. The pressure is reduced in steps, and at each level as much gas is removed that the volume of the remaining gas and oil mixture equals the saturation point volume.


For each reservoir fluid tune to saturation pressure at the reservoir temperature and the critical temperature determined in 4. Quality check for fluid sample, create QC report.


One of the most challenging EoS modeling tasks is to develop a common EoS model for multiple fluids with gas injection. PVTsim allows in-depth properties simulation and research of fluids and with different embedded function modules. For each fluid to be represented using a Common EoS model, pvtsik the following i. Density of reservoir fluid from flash to standard conditions STO oil density.


It is too low if the liquid dropout curve increases too little with decreasing pressure. This is reflected in the simulated liquid dropout curves in Figure 3. Check whether the critical temperature of the reservoir fluid is too high or too low.

Figure 2 shows two phase envelopes. Read more about Courses. Calsep has more than 30 years of experience working with the pvtsom industry on projects related to reservoir fluid phase behavior. This experiment is performed for gas condensates and volatile oils. Services International experts in EOS modeling Calsep undertakes fluid modeling studies assessing all stages of production.

PVTsim Nova was launched May as a new generation of the PVTsim software package that has been continuously developed since the first version was released in The experiment is usually started at the pvgsim pressure. It is a further requirement to have access to a multi-fluid common EoS characterization procedure as described by Pedersen et al.

A wide range of applications, covering the entire oil and gas chain.

Carry out a plus regression Christensen, Simulate the swelling experiment. Calsep offers open courses as well as in-house courses to reservoir engineers, process engineers, engineers dealing with flow assurance or multi-phase flow metering, laboratory staff and others needing to apply PVT simulation software in their work.

It is a requirement that swelling data exists and the swelling experiments have been continued until the saturation point changes from a bubble point to a dew point as sketched in Figure 1. The good match is achieved solely by tuning to a critical temperature of o C and to the saturation pressure at the reservoir temperature.

Board index All times are UTC.


;vtsim Such adjustment is justified because of the experimental uncertainty on the plus molecular weight. By manual input or from its database, PVTsim can obtain the fluid information for quality check and related simulation. The saturation point volume, Vsat, is used as a reference value and the volumetric results presented are relative volumes, i.

Simulate the critical point of the reservoir fluid. Repeat this step manually to reach C The studies may cover the effect of injection gas in the reservoir for EOR purposes as well as the risk and mitigation of solid precipitation in wells and pipelines.
