History v.8.0 is MS Windows application for well monitoring time-based data review.

Historical data originated from WellDaq data acquisition and stored by the MS SQL Server are presented in numerical and graphical forms.

User screen displays simultaneously eight graph plots versus time and their momentary values.

Two charts contain four data plots versus time each. Data for each plot can be selected from a drop-down list. Each plot value scale can be set independently. Common time scale can be set for all plots.

Chart cursors can be set at a certain time point which is then displayed in the top of the screen. Momentary data values at that time point are displayed in appropriate fields. Corresponding well depth parameters are also displayed at the same time.
