FIBER OPTIC NETWORK SIMULATION:

All-optical networks show great promise for providing the bandwidth needed for the Next Generation Internet and its high-demand applications. However, optical testbeds have tended to feature circuit switched architectures and use of wavelengths for facility provisioning. All-optical packet network systems have posed several technical challenges, including the need for optical buffering, optical routing logic, fast tunable devices and design. Broadcast-and-Select single-hop optical packet networks have been extensively studied and modeled.

MetroOptic is a PC-based network design tool developed for metropolitan network planners that want to evaluate the trade-off between traditional and emerging technologies with a mix of services, or for metropolitan network equipment vendors who want to demonstrate the validity of a customer proposal or determine the trade-off between equipment capability and network cost. Likewise, service providers can use MetroOptic to evaluate network configuration and demand provisioning. MetroOptic's capabilities enable network planners, equipment vendors, and service providers to efficiently determine the impact of new technology on network economics. For example, MetroOptic can determine if it is cost-effective to implement WDM technology into an existing SONET network; and if so, MetroOptic can optimally configure fiber usage, equipment usage and placement, demand routing, and ring and point-to-point system placement in the network to incorporate the WDM technology with many vendor products.

MetroOptic is a vendor-neutral strategic network-planning tool that simulates and analyzes SONET/SDH and DWDM systems in metropolitan environments. MetroOptic's flexible equipment, cost, and demand models are designed to locate cost-effective DWDM and SONET/SDH rings in the network backbone. The software is ideally suited for designing metropolitan environments because it places the fewest possible number of ADMs in the network, which is the greatest expense of any metropolitan network. MetroOptic also places amplifiers and regenerators only where needed and according to metropolitan network standards.

MetroOptic's easy-to-use interface enables you to quickly create a network model, enter data, select options, run a study, and view results. After you run a study, the interface provides visual representation of rings, ADM nodes, demand routing, clusters, and homing, as well as access to a rich set of reports that enable you to slice the data and analyze options, especially for node equipment and link costs.

OIL and GAS PIPELINE SIMULATION:

Pipeline and Process Facilities Engineering. The Pipeline and Facilities module in PIPESIM 2000 allows detailed flow modeling from the wellhead through to the delivery point. This module captures horizontal / vertical flow and surface equipment simulation. Detailed understanding of the system hydraulics is critical to many flowline design and flow assurance issues particularly for complex multiphase systems. If required, wells can be built into the same system model to simulate flow from the reservoir. It is also possible to embed your PIPESIM 2000 model into the process simulator, HYSYS**.

The Network Analysis module is the PIPESIM 2000 successor to PIPESIM-Net.
It is a comprehensive multiphase pipeline and well network analysis tool that enhances PIPESIM 2000's Well Performance and Pipeline & Facilities modules to enable the modeling of complex gathering, distribution and looped networks. A robust network solver combined with an efficient Windows GUI provides rigorous and easy to use production network modeling.

The Network Analysis module uses a powerful solution algorithm. This means that as well as gathering networks, users can model distribution and injection systems with multiple delivery points including networks with loops, parallel lines and cross-overs. Network Analysis follows multiple streams from separators allowing tracking of separated produced oil, gas and water. The system is solved with the same rigorous thermo-hydraulics as the single branch PIPESIM 2000 well / flowline systems. Separate fluid descriptions can be set at each source point in the system. Detailed fluid mixing is conducted at junctions.

The PIPESIM 2000 network module is fully integrated with the single branch models using a common GUI. Key benefits of this are:

• Individual branches within a network can be studied in detail.
• Fast and efficient model building for large networks.
• Sections of the network can be contained in 'folders' - useful for large networks!
• Consistent reporting of results and graphs.

Typical Network Analysis includes

• Calculate deliverability of complex systems.
• Predict pressures and temperatures through complex flow paths.>
• Identify bottlenecks/constraints.
• Flow assurance issues (slugging, erosional velocity).
• Backout effects of new wells coming into production.
• Mechanistic Production Allocation.
• Quantify benefits of more wells, new pipelines, compression etc.
• Field planning.

Global vs. Local settings
Fluid descriptions and flow correlations can be set globally (applied to the whole model) or locally for each specific branch.This provides additional detail if different reservoir fluids are commingling into a main production system.
Network Analysis Equipment Models
Separators, Pumps, Multiphase Boosters, Compressors, Expanders, Heaters and Coolers, Chokes.
Integration and Connections
Network Analysis includes all Pipeline & Facilities and Well Performance module features, and is an integrated component of the PIPESIM 2000 FPT (Field Planning Tool). This provides Reservoir models and links to external Reservoir Simulators (ECLIPSE*).

Network Analysis is linked with other external packages

• Export data to Microsoft Excel*** and other packages.
• Link to your field data using ProdMan.
• OpenLink a user configurable general link.
