Gas Lift Optimisations Gas Lift Optimisations (Onshore/ Offshore) (Onshore/ Offshore)

To optimise the gas used for gas lift To optimise the gas used for gas lift based on best possible oil based on best possible oil production from wellproduction from well

This is a model based optimisation This is a model based optimisation package which need input from well package which need input from well test to know the oil and gas flow of a test to know the oil and gas flow of a particular wellparticular well

Lift Curves are generated by the Lift Curves are generated by the model or can also be manually fed to model or can also be manually fed to the systemthe system

GLO provide an output which is a GLO provide an output which is a reference to the flow / pressure reference to the flow / pressure control loop of lift gas circuitcontrol loop of lift gas circuit

The automation system uses these The automation system uses these reference to control the flow of lift reference to control the flow of lift gas in the well annulusgas in the well annulus

The GLO helps in managing the Lift The GLO helps in managing the Lift gas network created for different oil gas network created for different oil wells in same or adjacent oil fieldwells in same or adjacent oil field


Asset /Field and Pipeline Mass Asset /Field and Pipeline Mass Balance (Onshore/ Offshore) Balance (Onshore/ Offshore)

Asset/Field Mass balances are Asset/Field Mass balances are applied to the facilities. Imbalance is applied to the facilities. Imbalance is indicator of leakagesindicator of leakages

This is based on Current day, This is based on Current day, Current Hour and Previous Day, Current Hour and Previous Day, Previous our flow estimationsPrevious our flow estimations

Pipeline mass balances is to identify Pipeline mass balances is to identify imbalance for facilities linked imbalance for facilities linked through pipelinesthrough pipelines

Imbalance is indicator of theft or Imbalance is indicator of theft or leakageleakage

In case of Gas Pipeline Line pack In case of Gas Pipeline Line pack calculation based on pipeline calculation based on pipeline segment and is must as change in segment and is must as change in line pack can provide imbalancesline pack can provide imbalances

In case of liquid pipelines if the In case of liquid pipelines if the temperature variation across the temperature variation across the pipeline is considerable then only pipeline is considerable then only change in line pack has impact on change in line pack has impact on imbalance imbalance
