Brief description of SGTPIPE / SGTFLOW application suite

SGTPIPE / SGTFLOW application suite is designed for pipeline network analysis and optimization at oil producing companies. Pipeline networks include: Oil gathering system Reservoir pressure maintenance system Single high and low pressure water pipelines, oil pipelines and gas pipelines (with some restrictions).

The application suite meets the following challenges:

• Quick hydraulic calculation of pipeline networks, current status analysis, ”bottle neck” detection and simulation of measures to remove it.
• Pipeline network optimization within remedial and reconstruction scheduling.
• Economic evaluation of corrosion inhibitor protection effectiveness.
• Calculation of chemical agents’ distribution and optimization of their use in pipeline networks.

The application suite consists of 2 parts:

1. Graphical database SGTPIPE used as a graphical user interface in Microsoft Visio 2002 Pro.
2. Calculation module SGTFLOW, simulating oil-water-gas mixtures and chemical agents flow in relief pipeline networks. Operated with Microsoft Windows 2000 or higher or as a stand-alone module for Linux.

SGTPIPE

Application

Designing technological diagrams of various Pipeline networks such as oil gathering system, water pipeline in reservoir pressure maintenance system, crude oil pipeline, gas pipeline, etc... Entering, processing and visualizing technical attributes and technological parameters of operated objects.

SGTPIPE features

• Graphical design, storage and visualization of pipeline technological diagrams.
• Input, storage and visualization of technical attributes and technological parameters of pipeline network elements (Sources, sinks, pipeline segments, pipeline tie-in points...), including hydraulic calculation results.
• Classification and search for used objects by their attributes (by means of Microsoft Visio).
• Entry completeness and correctness check.
• Interaction with hydraulic calculation module of an oil-water-gas flow in complex pipeline networks (SGTFLOW).
• Visual analysis of calculation results.
• Running various reports in Microsoft Excel, such as :

- Main pipeline list - Hydraulic parameters of pipelines operation - Remainders of oil, water and free gas in pipelines - Corrosion velocity and pipeline hydraulic modules. - Oil, water and gas production

SGTPIPE advantages

• Microsoft Visio as a graphical editor comprises a huge amount of features, development and support from Microsoft, storage and schematic representation of any vector and raster object. It allows creation, verification and simulation of a small pipeline network diagram within an hour with later modifications and quick model calculations.
• Data storage in Microsoft Visio. All graphical and attributive data including calculation results is stored in one Microsoft Visio file and therefore can be transmitted, archived, copied, etc. independent of Visio and SGTPIPE.
• Quick training to operate with SGTPIPE. Presentations, diagram examples. Implementation and further support.
• Possible adaptation to each client (new data, reports, interface modification…).
