This package calculates the data needed to construct and analyze Hearn plots.
Usage and Configuration
Run the workflows from this package to perform the calculations. The schedules may be adapted to use different contexts.
The script Hearn Plot Visualization can be used to extract the data needed to create Hearn plots in a dashboard.
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 HierarchyFormationWellRelationships to configure which hierarchy contains information about the relationships between formations and wells.
Use the workspace value FreshwaterPressureGradient to configure the pressure gradient of freshwater.
Use the workspace value WaterSpecificGravityLiterature to configure the specific gravity of water based on literature.
Use the workspace value DataLoadOffsetDays to configure the end of the scopes Start To Date Daily and Start To Date Monthly.
E.g. If the data in the data sources is lagging one day, set the workspace value to 1 to account for this offset.
The upper and lower thresholds, which are used to detect the wellbore plugging and fructuring respectively, must be configured by the user when setting up the workflow Hall Plot Surveillance.
The user must set up the average perforation depth when setting up the workflow Hall Plot Surveillance.
Details
The slope angle of the Hearn plot is categorized into two categories according to the following logic:
- wellborne plugging: the slope angle is > upper threshold
- fracturing: the slope angle is < lower threshold
Data Requirements
The following data is required on well level:
injected water per time increment
reservoir pressure
injection pressure
perforation bottom
well head pressure
bottomhole pressure
perforation top
water injection rate
