Yggdrasil is a specialist company providing inte-grated flow assurance servicesand solutions to the upstream oil and gas industry.At the core of our business is METTE - a powerful life-of-field simulator for design and operation of multiphase production systems.

An integrated flow simulatorMETTE is an integrated flow simulator including well performance,network optimization, virtual metering and transient simulations with built-in interfaces to reservoir and process simulators.The integrated approach benefits users by providing a single application for all types of flow calculations. It facilitates cross-discipline understanding and improves consistency in data use through commonality of input data.

Dramatic improvements - efficiency, costs and quality METTE offers unique improvement opportunities, whether you choose to use her with your own specialists or employ the expertise of Yggdrasil.The capabilitiesof METTE will impact on your work flow, providing quantitative data invaluable for field development, engineering or daily operational decisions.The efficiency of METTE provides more for less.

Faster, better and safer decisions

An indispensable everyday engineering tool for integrated flowassurance and productionoptimization

From reservoir to topside processesA key driver behind METTE has been to provide the industry with an easy-to-use practical engineering tool applicable throughout the life of a field - stimulating multidiscipline collaboration, streamlining work processes and improving consistency in data use.The open architecture of METTE provides for simple interfacing with bothreservoir and process simulators for seamless calculations from subsurface to topsides.It is easy to implement third party dll

,s for different unit operations.

Use METTE to:- Establish concept-dependent production profiles accounting for defined sytem constraints- Evaluate tie-back of new reserves to existing infra structures- Get optimized predictions for gas lift and continuous hydrate inhibitor needs using

multiple interfaced networks- Perform transient simulations for thermal insulation requirements, blow-down

volumes and adverse effects of inadvertent events- Calculate network mass and energy balance variations over field life

- Find optimized set points to achieve defined production targets within defined production constraints

- Quantify effect of removing defined bottlenecks.- Process field data to get individual well production

Performance calculations Simple Integrated flow assurance

Performance calculations in METTE are very flexible.Analyze well or flow line capacities using multiple boundaryconditions. Include multipliers for diameter, PI and phase slippage to quantify the effect on production potential.Analyze the effect of gas lift amounts and injection depth.Calculate set points for chokes, compressors or pumps forgiven input parameters. Inspect variations in key parametersalong flow trajectories. Calculate well and flow line potentialswithin a network from defined boundaries.

The free Excel add-in provided with METTE is an alternativeentry-point to well and flow line performance calculations.Using the template interface provided, result data are organizedin pivot tables for simple data analysis.

Flexible Fast Life of fieldNetwork simulation

For producing fields METTE provides total production management capability - including a virtual meetering module for calculating well phase flow-rates ‘.

...crazy!

Providing input to METTE is easy. Use the interface to define flow trajectories or import from PetrellTM,Tempest MORETM or from ExcelTM. Create flow networkswith simple mouse operations. Add components like compressors, pumps and choke valves by simply draggingand dropping onto the flow trajectories. Include sensorsfor use with virtual metering or monitoring of key data.Apply default component parameterizations and refinewith actual vendor data.

Use common input for well, flow-line and network performance calculations, life-of-field and transient simulations as well as virtual metering interpretations.

Providing input

METTE employs a very fast and robust solution algorithm.The speed makes it an indispensable everyday engineeringtool for flow simulations. Interface multiple reservoirsimulation processes at time-step level for seamless calculations from subsurface to topsides, removing the needfor VFP tables. Employ the powerful event module to includeconditional changes in boundary conditions. Change deliverypressure, production constraints, the activation of boostingequipment and other relevant parameter selections.

Use the multiple network capability to calculateproduction and service networks like gas lift orMEG supply at the same time.

A true benefit of METTE lies in its integralapproach. It is equally useful for early stageconcept evaluation as for providing answers to everyday operational issues.

With the high calculation speed of METTE, concept-dependent production profiles are available at your fingertips. Use case definitions for efficient system sensitivity analysis. Evaluate timing for tie-back of newreserves, phasing of wells, well-routing, pressure-boostingand artificial lift.

Interpret field sensor measurements using the virtualmetering (VM) module. It provides an excellent andextremely cost-efficient alternative or supplement tomultiphase meters.VM results can be used with reservoirmodel history-matching as well as daily production allocation.The combined VM and forecasting capabilitymakes METTE a powerful production management tool.
