| Popis: |
The infill potential of a waterflood project in a transition zone carbonate reservoir has been revised through the usage of logging while drilling (LWD) data in horizontal wells. The North-Western flank prospective has been unlocked by unravelling lateral variations on reservoir architecture and generating an alternative fluid fill concept for transition zone saturation. The field is developed through horizontal wells with only five vertical penetrations that are clustered in the southern part of the field. Data analysis of the vertical wells supports the log response calibration, relating architecture and fluid fill to saturation models. The high density LWD data allows the coverage of the North Western flank. An alternative fluid fill scenario related to tectonic structural changes after charge (as previously published in 2016, SPE 181401) is consistent with vertical wells and LWD data and reflects an upside for the North-Western flank saturation. The alternative fluid fill concept reflecting post-charge tectonic changes of the structure has improved the North-Western flank saturation and infill potential. With the alternative concept, now in alignment with actual LWD measurements, the history match of the oil production of the flank sector has been achieved. An appraisal well is planned to assess the potential of the area. |
