A major issue petroleum companies have with unconventional resource plays, is identifying prospective areas early in exploration stage. Early land captures of contiguous blocks at reasonable entry, exploration and appraisal costs are critical to the economic success of the program. The Duvernay shale play in Western Canada is an excellent example of an emerging play. During exploration efforts, the Kaybob area was identified as highly prospective.
This study takes advantage of this emerging play to illustrate the use of logs, calibrated with core to identify and characterize prospective zones in the Duvernay Shale. Well log facies and petrophysical parameters based on 3-D static models were used to determine the production potential within the Kaybob area and the associated uncertainty.
The model result and the first three months normalized production comparison show positive trends. The result also indicates that there are multiple factors that contribute to a good producing well.
