Reservoir Surveillance and Control

Competency Statement:

Understand and apply reservoir surveillance and control techniques to confirm the materialization of the proposed strategies in the reservoir exploitation scheme

Learning Objective:

Upon completion of this module, the participant should be able to

  • compare actual reservoir behavior to various performance prediction tools and account for differences
  • evaluate the effectiveness of the exploitation strategy

explain reasons why actual reservoir performance deviated from initial predictions

Assignment Instruction:

The Upper/Middle Sands have been on production for more than 20 years, 15 of them under waterflood. On the basis of daily average production, this reservoir has already passed its economic limit, with water cuts routinely exceeding 90 percent. But thanks to the efforts of field personnel in applying good production practices and bringing operating costs down to a minimum, the field is still making a small profit. It remains to be seen whether this field has additional potential through a realignment of the waterflood or implementation of enhanced oil recovery methods.
