This study has been done on Late Cretaceous tight clastic reservoir located south west of Abu Dhabi city with the border with Saudi Arabia. The field was discovered in the 1960s and a few wells were drilled subsequently. The Tuwyail clastic reservoir is characterized as tight with average permeability below 1 mD. The trap is identified as structural trap as north south anticline with gentle dip in both sides. Total of six wells were drilled targeting Tuwyail reservoir which part is of Wasia group. However, assessing potential of this accumulation poses a great challenge not only in terms of understanding of the depositional system which still unknown before but also in terms of quality of the legacy data like well data that impact the modeling studies. The aim of this paper is to provide an insight on integrated workflows for assessing the different uncertainties on clastic systems with limited data, focused on the most important sensitivities parameters impacting the oil in place, like reservoir proportions, free water level [FWL] and lateral distributions of the sedimentary elements within the area of interest which playing a big rules in future developing of the field. Before moving to full field development a full uncertainty and sensitivity analyses were conducted for the Tuwayil reservoir to find the highly uncertain parameters that impacting the future development of the reservoir, in the same time the main challenges is the limited data with low quality as the wells had been drilled in 60s with limited technology at that time and the core data were left in a bad conditions since the filed was left behind. |
