Packages
Survival Analysis (Gas Lift) Package
Calculate survival curves and hazard ratios for Gas Lift wells.
Usage and Configuration
To perform the calculations run the workflows from this package starting with the workflow Survival Analysis (Gas Lift). The schedules may be adapted to use different contexts.
Follow the steps given in How do I configure packages pulled from Datagration's package repository to change the configuration of the package.
Use the workspace value DataLoadOffsetDays to configure the end of the scope Start To Date Daily.
E.g. If the data in the data sources is lagging one day, set the workspace value to 1 to account for this offset.
Details
Workflow Survival Analysis (Gas Lift)
This workflow calculates survival curves and predicts hazard ratios for Gas Lift wells.
Survival Curves (Gas Lift)
This activity generates survival curves and stores them as json string. For more information about the generation of survival curves refer to the documentation of the Remaining Useful Lifetime package.
Survival Analysis (Gas Lift)
This activity predicts hazard ratios for Gas Lift wells using the specified Survival Analysis ML model. For information about creating and interpreting these models, please refer to Survival Analysis in PetroVisor.
Data Requirements
The following data is required:
gas injection rate
runtime between failures
