Senior Reservoir Engineer with Kuwait Oil Company, currently leading the Marrat reservoir, one of the most technically challenging deep carbonate reservoirs in Kuwait. Specialize in reservoir studies, integrated modeling, and field development planning for complex, high-pressure, high-temperature carbonate systems.
Graduated from Kuwait University in 2013 with a degree in Petroleum Engineering and joined Kuwait Oil Company in 2014. Since then, I have built broad operational and technical experience through roles in production and operations teams before transitioning into the reservoir studies team. This progression has given me a strong end-to-end understanding of field performance, data uncertainty, and practical constraints affecting development decisions.
In my current role, I lead multidisciplinary teams across subsurface and surface disciplines, integrating geology, petrophysics, drilling, production, and facilities inputs to deliver robust reservoir models and development strategies. My work focuses on de-risking deep carbonate developments, optimizing recovery, and ensuring technically sound, economically viable field development plans for long-term asset sustainability.

To reach Kuwait’s oil production target, production enhancement from tight carbonate reservoirs is essential. In this paper, it will be demonstrated how an integrated workflow that includes advanced reservoir characterization to optimize the stimulation design with enhanced zonal coverage in a heterogenous Jurassic reservoir.
Methods, Procedures & Process:
To accurately select the candidate based on precise determination of the reservoir permeability contrast across the different layers. Representative fluid samples have been captured to map the asphaltene envelope. The injection logging survey was a key input to determine the permeability profile and to evaluate the integrity of the patchy cement through temperature analysis. Pressure Transiet Analysis (PTA) were essential to evaluate the significance of the depletion across the different areas of the field as well as to determine the total skin of the reservoir. The integration of these data in a structured workflow enhanced the stimulation design.
Results, Observations & Conclusions:
Based on the significant permeability contrast, Single-Phase Retarded Acid (SPRA) and Bio-degradable Particulate Diverters (BPD) were found to be essential to unlock the tighter layers. Five wells were stimulated utilizing the above workflow resulting in 7 folds of increase in the oil production versus 4 folds of increase before implementing this workflow. Another important observation is the sustainability of these wells for over 1 year with less frequency in asphaltene clean-out treatments.
It can be observed that meticulous characterization, planning and execution for tight carbonate reservoirs is critical for a sustained production enhancement. This reservoir oil production has increased by 150% from existing wells with rigless intervention.
New Information to Existing Literature:
This paper demonstrates the economical development of deep tight carbonate reservoirs through fit-for-purpose workflows. The findings were utilized to update the full field development strategy.
