Realising Opportunities Using Integrated Production Modelling in Occidental of Sultanate of Oman

Abstract

Integrated Production Model IPM is a numerical simulation model using rigorous physics to describe the behavior of an entire production system and produce optimization soulutions of any operated field by integrating the reservoir models, well models and the surface network model. Integrated production model using IPM suite (Petex) was implemented in field X mainly operated with gas lifted production system, which is located in the North of Sultanate of Oman. This is a distinguished, proactive and creative process of searching and realizing opportunities that are occuring in daily life of a producing gas lift field. The process has included four phases. First phase was characterizing, predicting phase behavior and dynamic fluid properties of reservoir fluid. Second phase was building field reservoir models in MBAL using material balance simulation. This helps predicting reservoir pressure and forecasting senarios. Third phase was modeling all wells in Prosper including all subsurface mechanical components and generate the vertical lift curves to examine production performance of the well at different welltest and reservoir pressure conditions. The last phase was building surface network model GAP and link that to all the reservoirs and wells models. At this point system response was validated and calibrated to represent actual field status. Going through the process of integrated production system modeling resulted in an increase of 8% of total field production by individual wells optimization. In addition more than 25% of gas lifted gas was saved through optimum distribution of lifting gas among the producers.

Development of Guidelines and Procedures for Value Addition to Improve Productivity and Sustainability: Case of Dates in Oman

“…Date palm is the permanent crop in Oman that covers a huge area with other fruit and vegetables. On the other hand, there is a high percentage of postharvest losses that may reach an average of 28% of fruits, including dates, and 30% of vegetables [7,20,21]. The concept of value-addition activities is marginal in the Sultanate of Oman due to the lack of awareness of their importance, the lack of technological support, and the unavailability of service providers of production processes, which leads to a low percentage of value-added products in local markets and poses weak competition against imported products.…”
