Forecasting
Forecasting module provides a PIBF (Productivity Index Based Forecasting) methodology to forecast well behavior.
As part of Forecasting, the following screens are available:
- Well and Asset Selection
- Toggle – IPR Transient and Forecast
- Chart Size selection
- Chart Area
- Map
On expanding well panel, we can select wells from a list of the wells as per asset selection. The following are the key information in the Well selection panel:
- Arrange by - Grouping wells as per group.
- Well Name – multiple well selection.
- Lift Type (in front of well names – such as GL). For example:
- W-GL Well 62 (Gas Lift Well)
- Error or warning (in front of Lift type)
Please note that it is possible to select multiple wells on this page. The data gets refreshed based on the well selection.
The transient IPR tab provides IPR curves after 0, 30, 60, 90 days of production.
- The current operating pressure and flow rate.
- The well is under natural flow, annular flow, or artificial lift.
- A user can select multiple wells to visualize at the same time.
Alternatively, a user can toggle to Forecast mode in which the comparison between actual production and hindcasted production is shown. It additionally shows the forecast for the next 30 days using PIBF method.
In the chart area, using the time duration and toggle configuration the data can be plotted for multiple wells.
This makes the entire comparison exercise and well performance evolution quite effective and efficient.
The map section provides a better way of user interaction in terms of selection of the well on a GIS map.
We can easily draw lines to select a group of wells that are geographically collocated and have a comparison study.
