Reservoir VietNam

Le Minh Vu, Tran Thai Son, Vu Viet Hung Excessive production of water in the naturally fractured basement reservoir has been one of the most intriguing problems in production engineering. Water may appear immediately at the early production stage or breakthrough after months on stream. Available methods to determine the source of produced water are entirely based on chloride content. The stiff diagram is one of the well-known graphical methods to confirm whether it is formation water by integrated various chemical components. With the Stiff diagram, the operators are able to detect formation water in the early days, which apparently assists in quantifying the potential of scale deposit, erosion, and so on. Apart from the water sources, it is crucial to understand the water-out mechanism also via a graphical approach. The characteristic trend of water-oil-ratio and its derivative with time in log-log plot indicates the variety of slopes reflecting different flowing mechanisms and...

Decline Curve Analysis: Forecast Oil-Water-Gas Decline curve analysis is conventionally applied for oil. Based on the graphs of Wct Vs Prod.Oil cumulative and Prod. gas cumulative gas vs Pro. oil cumulative, we can forecast Oil-Water-Gas in depletion.  Try and feedback! Download Click here

Hybrid System of ESP and Gas Lift Application from Conceptual Design, Pilot Test to System Analysis Artificial lift technology application in heavy oil production has been far-reaching developed in the industry over past decades by persistent efforts to improve the ultimate recovery of this “difficult” hydrocarbon. Heavy oil discovery in a marginal field, Cuu Long Basin, Offshore Vietnam is relatively aberrant and pose challenges to full field development. A series of systematic technical studies have been purposely planned from the first discovery of heavy oil in the wildcat well to the modeling study and facility design to accommodate the viscous fluid over the field life. Apart from the thermal method, pumping technology makes remarkable advance by enlarging the drawdown created over the conventional gas lift in several heavy oil projects. After due consideration, the Electrical Submersible Pump (ESP) was finally decided as the key driver to reinforce well production performanc...
