Conventional Well Optimizer
Overview
The Conventional Well Optimizer is a powerful tool designed to help you plan the optimal placement of conventional wells within specified geographical boundaries (contours). Unlike unconventional wells that require complex layouts with laterals and multi-well pads, conventional optimization focuses on maximizing field coverage using individual wellheads that drain a specific geometric area (drainage polygon).
In Conventional mode, the optimizer assumes 1 Pad = 1 Well, without any lateral segments.
Step-by-Step Workflow
1. Define the Development Area
Before running the optimizer, you must define the geographical area where the wells will be placed.
- Draw Contours: Use the map tools to draw polygons (boundaries) representing your target development areas. You can define multiple independent areas if necessary.
- Reference Coordinates: Establish a geographical reference point to anchor the optimization grid.
2. Select Conventional Mode
In the optimizer configuration panel, locate the Well Type toggle or dropdown and select Conventional. This will hide all lateral and pad-specific parameters (which only apply to unconventional wells) and display the conventional drainage settings.
3. Configure Drainage Parameters
Set up the physical properties of the reservoir drainage area that each well will cover. These settings dictate how tightly the wells can be packed without overlapping their theoretical drainage zones.
- Drainage Shape: Choose whether the drainage area around the well is a
Rectangleor aCircle. - Drainage Size X (Width): Set the horizontal width of the drainage area in meters.
- Drainage Size Y (Height): Set the vertical height of the drainage area in meters. (Note: If ‘Circle’ is selected, you may only need to provide the diameter).
- Drainage Azimuth: If using a rectangular shape, define the rotation of the rectangle in degrees (0 to 360). This aligns the drainage pattern with specific geological stresses or features.
4. Run the Optimizer
Click the Optimize button. The engine will calculate the maximum number of wells that can fit inside your drawn contours while respecting the designated drainage shapes and orientations.
5. Review Results
Once the backend finishes processing, the map will populate with the results.
- Well Heads: A marker is placed at the exact geographical coordinates for each calculated wellhead.
- Drainage Areas: A geometric polygon (rectangle or circle) is rendered around each well, indicating its drainage coverage.
- Metrics: You can hover over or click a well to see its exact
Drainage Area(in square meters) andDrainage Shape.
Glossary of Input Variables
Here is a detailed explanation of the variables you will encounter when configuring the Conventional Optimizer:
| Variable | Description |
|---|---|
| Well Type | Set to Conventional to activate this optimizer mode and hide lateral/multi-pad settings. |
| Contours | The geographical boundaries (drawn on the map) indicating where wells are allowed to be placed. |
| Drainage Shape | The geometric shape of the volume of rock drained by the well. Options are Rectangle or Circle. |
| Drainage Size X (Width) | The width of the drainage area in meters (Default: 500m). |
| Drainage Size Y (Height) | The height of the drainage area in meters (Default: 500m). |
| Drainage Azimuth | The orientation or rotation of the rectangular drainage area, measured in degrees from 0 to 360 (Default: 0°). |
Interpreting Output Data
After optimization, the system returns placement data for each well. For conventional wells, the key outputs rendered on the map include:
- Total Wells / Total Pads: In conventional mode, these numbers will be identical since each pad contains exactly one vertical well.
- Connector Head (Lat/Lon): The geographical placement of the physical wellhead on the surface.
- Drainage Polygon: The exact coordinate vertices mapping out the border of the well’s drainage area.
- Drainage Area: The calculated surface area coverage of the polygon in square meters.
