This thesis presents a detailed 3D static modeling study conducted in the Mazkhour
field, located in the north-western region of Oman, with a primary focus on the Upper
Shu’aiba reservoir. The main objective of this research is to construct a geostatic
model utilizing recently acquired data, specifically aimed at identifying and
characterizing reservoir features.
The Upper Shu’aiba reservoir is characterized by a succession of clinoforms that
prograde from the SW to SE, deposited during a regressive sea cycle within the Bab
basin. The reservoir units within each clinoform exhibit a consistent sequence of
facies. Notably, the proximal part of the clinoform emerges as the most favorable,
housing reservoirs with high porosity and medium permeability. Moreover, intraformation seals, primarily composed of argillaceous deposits, effectively isolate the
distinct clinoforms into individual reservoir units.
A key aspect of the study involves the stratigraphic correlation that identified three
main reservoirs within the clinoforms (i.e., A, B, and C). The research reveals that the
proximal part of the clinoform exhibits superior reservoir quality compared to its distal
counterpart.
The static modeling results validate the stratigraphic findings, illustrating higher
porosity and notable variations in water saturation within the identified reservoirs. The
culmination of these analyses enables a comprehensive estimation of oil in place
through volumetric calculations.
This research contributes valuable insights into the reservoir characteristics of the
Upper Shu’aiba Formation in the Mazkhour field. The 3D static model enhances our
understanding of the spatial distribution of reservoir properties.
