Introduction

Baker Jardine Update PIPESIM Update Gas Lift Diagnostic Gas Lift Diagnostics in Context


PIPESIM / Baker Jardine Update

Baker Jardine acquired by Schlumberger April 2001

Continue to Focus on PIPESIM Suite and ProdMan

Plus Integration with SLB Products e.g. Eclipse, OFM, Finder…

PIPESIM2000 launched. Development project to rewrite program

interface. Integration under one user interface.

What is PIPESIM 2000


Field Planning Tool

Allows PIPESIM 2000 Well / Network models to be linked with detailed reservoir descriptions Built-in models: Look-up tables, Blackoil /

Compositional Material balance models Reservoir models: Eclipse 100 / 300 and others

Allows time-stepping of the coupled model through field life

Includes field planning events controlled via an easy to use graphical user interface Time based events Conditional events


Gas Lift Diagnostics


Gas Lift Diagnostics

What is happening down hole? Is my well working correctly? Can my well be more efficient?

What data do I have?

What do I need to correct the problem? Can I correct the problem without

intervention? Do I need to collect further data? Can I justify the chosen course of action?


Traditional Approach

Analyse well by well – No targeting Analyse well when new data available Mostly analyse after Flowing P&T survey Occasionally analyse with new well test

First analysis leads to more data gathering Initiates use of chart recorders Cycle times on well optimisations can be

long


Production Challenges

The Challenge Better surveillance Faster problem diagnosis Optimum production operations

The Method Data management Apply simulation


ProdMan Features

Data Management Well tests, field data, SCADA & DCS data

Automated collection Presentation and trending to operators

Simulation Conversion of data into information with PIPESIM

2000 Automated Surveillance Diagnostics Constraint Management Real-Time Optimization

What’s Changing?

Field Automation Real time data on Engineers Desk Cheaper controls for continuous control

People Issues Fewer operational staff Monitoring more information Tend to be “Fire fighting”

ProdMan Gas Lift Diagnostic

Determine the status of each gas lift valve and how much gas is being passed

Automatic data retrieval Batch processing to screen large numbers

of wells Analysis capability to diagnose individual

wells


Gas Lift Diagnostic

Design Philosophy Use simulation to determine information Use real-time and offline data Design system to short list potential

problem wells Allows large numbers of wells to be

monitored Use available data

Increase in data provides enhanced diagnostic


Batch Processing

Focus on Wells with Problems


Gas Lift Diagnostic Calculations


Long term

Results stored to database

Builds history for well Reporting module


ProdManGas Lift Diagnostic One Part of ProdMan


ProdMan Focus

• Production Surveillance• Calculating unmeasured variables

• Comparing measured to calculated values

• Production Diagnostics• Well test analysis

• On-line Gas Lift Diagnostics

• Production Optimization

• Field wide production optimization

• Reacting to hourly changes in equipment availability

Conclusions

Automation is multiplying data availability Analysis must capture value in data

Tools should focus on presenting - The problems wells The complete picture to understand the

problem

The Challenge – Are you making the most of your data?
