Running the Norne case with Flow

Summary output

One of the main outputs from the simulator is the summary file (NORNE_ATW2013.UNSMRY), the ending UNSMRY means it is a unified summary file, i.e. containing data for all time-steps in a single unified file.

In this file you will typically find data that are likely to be useful to plot as a function of time, such as well rates, bottom hole pressures or fluid-in-place quantities. Flow allows the input deck to configure what should be written to the summary file. To look at the summary you may use the ecl_summary tool as was explained in the first tutorial (also you can use the summaryplot tool to visualize well curves as explained there):

cd out_serial
ecl_summary --list NORNE_ATW2013

This will give a huge list of keywords corresponding to quantities written to the summary. Some of the more important ideas to get from this are:

  • Keywords start with a letter signifying its scope: C for completion (well perforation), F for field, G for group (of wells), R for region and W for wells.
  • The rest of the keyword identifies the quantity, some examples (note that some of the concepts such as oil production rate makes sense and can be used with several of the scopes):
    • Well keywords (W): BHP for bottom hole pressures, GOR for gas-oil ratio, OPR for oil production rate, WIR for water injection rate.
    • Region keywords (R): OIP for oil in place, GIPL for gas in place in the liquid phase (dissolved in it).
  • The string after the colon (if any) is the name of the well or group, the region number, or (for completion data) the well name and completion location.

To get a particular quantity, for example the bottom hole pressure of the well C-4H, issue the command

ecl_summary NORNE_ATW2013 WBHP:C-4H

Note that when the well is closed, the BHP is reported as zero.

The units used in all summary (and restart) output files correspond to the unit family chosen in the input deck. For Norne, METRIC units are used, and so the BHP output is in bars, rates are in cubic meters per day etc. When FIELD units are used, BHP output will be in psi, rates in barrels per day for oil and water or 1000 cubic feet per day (yes, really!) for gas etc.
