Cel The aim of the project is to provide the working engineer with a suite of handy and validated Computer Aided Simulation Tools needed to analyse complex flow situations, to design equipments, perform operations, and operate facilities for oil and natural gas production and transport. The final product "the Integrated Simulator" will cover the following main working areas: (1) Diagnosis of pipeline and pipe network flow phenomena and design of relevant Hydrocarbons systems and equipment. (2) Prediction of mixed flow situations appearing in oil and natural gas operations: multi-phase flow phenomena, flow transients, surface separation processes, gas lift applications. (3) Thermodynamic modelling of petroleum fluids.Verification of the results and validation of the simulation ability of the system is the utmost task of the project. For this purpose, data from own experiments, field operations data of the supporting industry, published data by established institutions and, results of validated codes, will be integrated in for validation purposes.PHASE 1:Phase 1 is related to specific experiments in the facilities of Fluid Mechanics Lab. of the University of Patras. The objective of the phase is the experimental study of :* Air-Lift Pump Performance* Transient Fluid Flow in pipeline and pipe network configurations.For the conduction of the series of experiments the following steps are followed :1. Operation of the test facilities under steady state conditions. Calibration of the measuring devices. This task is completed.2. Operation of the test facilities for the selected range of operation conditions. Collection and evaluation of data.3. Creation of the software laboratory test bed.PHASE 2:The interactive monitoring shell of the computational system will be an advanced man-machine interface facility which will guide the user to access to the desired application. It is a pure software engineering work to be performed in this phase in order to enable system installation, in both personal computer and work stations.Flexible input facilities will offer easy problem definition, whereas the output of the results can be channelled to any peripheral facilities.PHASE 3:This phase covers necessary programming activities for the construction of new code modules and the modification and completion of existing codes in order to be analyzed and introduced into the integrated simulator system. Formal software engineering activities regarding algorithms effectiveness, range of application and error check analysis and verification has been performed.PHASE 4:Three phases oil-water-gas flows occur in the petroleum industry, since hydrocarbon reservoirs almost invariably contain water. Also, as the natural pressure of an oil reservoir decreases with production, water is often injected to boost the pressure. The objective of the work has been the validation of both simple correlations and design tools and more detailed and mechanistic models of processes. Focus has been placed on two key areas of three phase oil-water-gas flows, namely stratified and slug flow. In addition the accurate prediction of transition point between the these two flow regimes has been assesed.PHASE 5:The work completed during the phases is documented by technical internal reports (TIR) which will cover all physical, technical and mathematical subjects of the project as well as the programming and of computational subroutines. TIRs describe all technical/physical methods of analysis, the computer algorithms, the computational subroutines, the examples/testing material, the results of the system verification tests.
