... Abstract The paper considers the process of removal and accumulation of liquid in horizontal trunks of gas wells and land gas pipelines. A mechanistic model of the process is constructed, an equation is derived that describes the dynamics of the process of removal and accumulation of liquid...

... simulation case 3 precondition liquid petroleum engineer transient multiphase process flow scenario Introduction Tengiz Second Generation plant represents a typical upstream onshore receiving facility: three-stage oil and gas separation at the inlet, crude oil desalting and stabilization...

... the preparation of self-gasified biosystems and the implementation of the subcritical region (SR) under reservoir conditions. Gasified systems in the subcritical phase have better oil-displacing properties than non-gasified systems. The slippage effect determines the behavior of gas–liquid systems in the SR...

..., for example by well Gas/Oil ratio to maximise liquid production, in the new methodology wells are smartly picked to fulfill all export and gas injection targets. Another improvement in the model was converting the optimisation logic, which was previously based on scripts, into open and transparent workflows...

... predicted liquid slugs as pigging result versus real historical data. The consistency in results was reached by using accurate input data such as rigorous geometry, tuned fluid file for Tengiz oil, and accurate assessment of the real slugs. For instance, Plant separator level accumulation factor made both...

.... This paper describes the evolution and application of a new approach to performing well testing, clean-up and water separation and treatment in the Karachaganak field. It describes the methodology, challenges and strategies that were adopted to manage the liquids produced during the clean-up and early...
