The project aims to study the Mauddud and Thamama reservoirs in the Bukha field. This
is an offshore field located in the western segment of the Musandam Peninsula. Both
reservoirs are characterized by their natural gas and have been producing since 1994.
These carbonate reservoirs were formed during the Cretaceous age within a ramp system.
The primary lithological components identified in both the Mauddud and Thamama
reservoirs are predominantly limestone with interbedded shale. It is worth noting that
these reservoirs are tight, but they are highly fractured.
This project presents the results of the analysis, modeling, and interpretation of the seismic
data available from this field. This is followed by building a static model that encompasses
major and minor fault structures, pillar gridding, various horizons, zones, and layers. The
model also incorporates a property model that describes the primary reservoir facies and
fluids. This has assisted in enhancing the understanding of the structural characteristics
and reservoir properties. The gas volume estimated from the model amounts to 461 billion
cubic feet. The analysis of both porosity and permeability models showed that the
Mauddud reservoir exhibited a higher porosity, approximately within the range of 0.5 to
0.9, in comparison to the Thamama reservoir.
Moreover, the project includes a description of core samples collected from the well to
study the characteristics and properties of the reservoirs. The reservoirs were affected by
diagenesis processes, including dissolution, cementation, mechanical compaction, and
chemical compaction. These processes have led to the formation of highly fractured
reservoirs, primarily because of compaction, especially in the proximity to a major fault.
Both mechanical and chemical compactions contributed to a decline in reservoir quality.
In contrast, the dissolution process resulted in a positive impact on reservoir quality,
leading to higher porosity.
The project outcomes have contributed to the understanding of reservoir dynamics,
structural complexities, and the potential opportunities associated with hydrocarbon
exploration and production.
