WinLoG can display a wide variety of wells at varying levels of detail and complexity. Monitoring, extraction, injection, and almost any other type of well can be displayed on the borehole log.
Well completion details and data can be displayed graphically in one or more columns of the borehole log. The borehole log can contain an unlimited number of well columns. In addition, depending upon the type of well column, the well may contain an unlimited number of casings and piezometers.
The style and input for monitoring wells has been changed significantly in this version of the WinLoG program. These changes were made to allow for greater flexibility and accuracy in drawing and annotating wells. In order to maintain compatibility with previous versions of the program, three different types of monitoring well columns can be specified in a template.
Well Type 1 columns were first introduced in version 1 of the program and can be used for very simple well displays. All of the well information is represented by bitmaps, which can be customized by the user. This type of well column cannot be used for wells with multiple piezometers or varying casing diameters, and cannot contain annotation.
Well Type 2 columns were first introduced in version 2 of the program and can be used for more complicated well displays. All of the casings/screens and fittings are drawn to scale by the program. This type of well column can be used for wells with varying casing and screen diameters, but cannot contain multiple piezometers or annotation.
Well Type 3 columns are a new feature in this version of WinLoG and can be used to represent complicated well details. Almost all of the well information is drawn to scale; including casings, screens, covers, caps, and miscellaneous fittings. This type of well column can contain multiple piezometers, casings, and screens with variable diameters, annotation, and multiple water depths. Besides being able to represent very complicated wells, this type of well column is also very easy to use and is recommended for most well displays.
The data for each well column is grouped into datasets and stored according to the name of the well column. This allows for the display of more than one set of well data on a borehole log. If the name of the well column in the template is changed after the data is entered, the dataset will no longer be displayed in that column. You can change the name of the well dataset for the log to that in the template as described below.
When a new borehole log is created, well datasets will be automatically created for whatever well columns are specified in the template. The names of these well datasets will appear in the Well Data submenu of the Edit menu. It is also possible to create additional well datasets or delete well datasets as described below.
