The thermal conductivity is an important parameter in engineering calculation. It enters into models and correlations for heat exchange in pipe and process equipment. The thermal conductivity (λ) is defined as where q is the heat flow per unit area and dT/dx is the temperature gradient in the direction of the heat flow. For oil …
UPDATES AND BUG FIXES IMPORT OF PVT DATA UPGRADE TO PRODML 2.1 The option for importing an XML file in PRODML format now supports PRODML version 2.1. IMPORT OF PVT DATA FROM EXCEL SHEET The option for importing an XML file in PRODML format has been upgraded to support automated import of PVT reports in a Calsep …
Just 10 years ago, the oil industry primarily saw CO2 as a gas that could potentially be used to enhance the oil recovery through injection into oil reservoirs. CO2 is relatively miscible with heavy hydrocarbons and a miscible drive can develop at moderate reservoir pressures. Today, much focus on CO2 has shifted to Carbon Capture Storage (CCS). It …

Accurate correlations exist for the density of pure water. An example is the model of Keyes et al. [1], which is used in PVTsim Nova. Formation water produced together with gas and oil is not pure, but contains dissolved salts, and these salts can have a significant effect on the density. The importance of water …

Calsep recently obtained a Court ordered preliminary injunction against the developers of a competing PVT simulator. The lawsuit is currently pending in the U.S. District Court in Houston, Texas. In March 2019, Calsep sued its former global sales manager, Pashupati Sah, and his business colleague, Ashish Dabral alleging that Sah and Dabral, working together with …
PVTsim users often ask why we do not assign any importance to Hoffmann plots in the QC module of PVTsim Nova. The idea of a Hoffmann plot is to validate whether a gas and a liquid separator sample are in equilibrium at separator conditions. The below table shows a recombined reservoir fluid composition for a …
PVTsim Nova 4.3 has been released. INSTALLATION Sentinel Dongle driver updated to support Windows 10 update 1803
Gas condensates are often saturated with water at reservoir conditions. A PVT laboratory will remove the water from a gas condensate sample before carrying out any experimental studies. Measured liquid dropouts in routine CME or CVD experiments are therefore for the water free fluid. The question is often brought up what impact it would have …
