The on-line flow rates and flow assurance calculations are

based on a set of state-of-the-art mechanistic models for

multiphase flow, and a fully-fledged compositional model

of the fluid. A network solver calculates the properties through-

out the network of wells and flow lines simultaneously -

providing estimates on a continuous basis.

This field-wide approach guarantees maximum sensor redun-

dancy, and sensors can be evaluated by consistency checking.

This way, the system can provide an alarm in the case that a

sensor reading is not consistent with the calculated flow rates.

If the number of sensors is higher than required for calcu-

lating the flow rates, the OptimizeIT Well Monitoring System

can also perform on-line estimates of failing sensors.

Running on a Windows® 2000 PC, and utilizing the most

common industry standards for program implementation and

communication, the OptimizeIT Well Monitoring System can

easily be integrated with any kind of production control

system. The information provided by the OptimizeIT Well

Monitoring System can be transferred to the production

control system database, and may be sent to a remote

operations center for closer analysis.

An Introduction to OptimizeIT Well Monitoring System

OptimizeIT Well Monitoring System is an advanced software package supporting efficient recovery of hydrocarbon resources from offshore and on-shore oil fields. The major application area is on-line calculationof oil, gas, and water flow rates from each individual well. The system can also handle flow assurance applications, and can be used for detecting erroneous sensors, and replace them as a ”soft sensor”.

Features

What it means to you

• Calculates the flow rates of oil, gas, and water as a data reconciliation tool

• Utilizes state-of-the-art mechanistic modelsfor multiphase flow, and a fully-fledged compositional model for the fluid

• Utilizes network redundancy, and can be operative even if a particular sensor is unavailable

• Designed as a stand-alone Windows®

2000 application, which can be integrated with any kind of production control system

• Based on an information system architecture (COM+), which makes theapplication easy to expand to handle any number of wells

• Member of the ABB OptimizeIT Enhanced Oil Production suite of applications

• Improved reservoir management, due toreal-time allocation of the total production from the field to the various zones in the reservoir

• Increased throughput, due to less frequentwell testing and early detection of gas orwater breakthrough

• Improved management of production on a daily basis, due to an overview of theflow everywhere in the production system, component-by-component

• Increased instrumentation redundancyand validation of measurements

• Reduced need for unplanned workoversdue to the instrumentation redundancy

• Improved Flow Assurance Surveillancedue to the real-time information on pressure and temperature throughout the production network

• Easy to scale the system - functionality and size

• Lower installation and maintenance costs,as compared to any hardware solution
