#21 Common EoS Modeling
The two first TechTalks in the series on Fluid Characterization dealt with characterization of single petroleum reservoir fluids. This TechTalk outlines How to make a common equation of state (EoS) model applicable for multiple fluids How to add a new fluid to an existing EoS model How to evaluate whether a series of plus fluid

Calsep Wins Lawsuit Against Calsep’s Former Global Sales Manager Pashupati Sah, His Business Colleague Ashish Dabral, and their Related Companies
In March 2019, Calsep sued its former Global Sales Manager, Pashupati Sah, and his business colleague, Ashish Dabral alleging that Sah and Dabral had used Calsep’s stolen PVTsim source code to develop a competing PVT simulation software called InPVT. Final judgment and damages On 19 July 2022, the Federal Court in Houston, TX issued its final judgment in the case. Calsep is
#20 Dealing with Mud Contaminated Samples in EoS Modeling
Taking a representative bottom hole fluid sample is a tedious and therefore also an expensive operation. Before a clean fluid sample can be taken, the well must be flooded for some time to remove the oil-based mud (OBM) in the near well bore area. Subsequently, a stable flow must be established from the cleaned well.

#19 Reservoir Fluid Characterization
Calsep will over the next couple of months post a series of TechTalks about simulation of fluid properties covering: Basic fluid characterization, Mud contaminated samples, Common EoS, Fluids with water, and CO2 rich fluids. This first TechTalk is about characterization of a single clean reservoir fluid composition. Fluid characterization was a hot topic in the

# 18 Adding a New Component into PVTsim
Introduction PVTsim has a comprehensive list of pure components covering not only oil and gas components, but also water, hydrate inhibitors and salts. Simulations may still be needed for mixtures with components that are not in the pure component database that comes with a PVTsim installation. In such cases, the user has the option to
