The climate debate has made CO2 one of the most talked about substances. In the oil and gas industry, CO2 has always been important. Most reservoir fluids contain CO2, some in large concentrations, and CO2 is an efficient injection gas for EOR purposes. The properties of the hydrocarbon components are the same in a CO2 …
Reservoir fluid characterization is no longer limited to the classical steps of splitting the plus fraction into carbon number fractions, lumping of C7+ fractions, and assignment of EoS model parameters to the pseudo-components. An EoS model must be applicable not only in reservoir engineering calculations, but also in flow assurance and process calculations. Produced reservoir …

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 …
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 …
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. …
#20 Dealing with Mud Contaminated Samples in EoS Modeling Read More »
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 …
