Le Minh Vu The heterogeneity is a major factor affecting oil recovery efficiency, especially in marginal fields. This heterogeneity is expressed through the sand connection and the compartment. The producers of this object often have a high-pressure decline. Assessing the degree of connection between blocks through interference is necessary. This result will help to optimize the development plan to achieve maximum oil recovery. In this article, the author will synthesize the design process and interference analysis. This process has been developed and applied practically at X field, the lower Oligocene reservoir. The results of the evaluation are based on dynamic data.  An assessment of the fault seal capacity is beyond this study. The Lower Oligocene reservoir belongs to X Field, offshore Vietnam. This is a saturated oil reservoir which is a thin oil rim and a gas cap on the top. The results of the interfering evaluation have indicated that the reservoir is divided by fractur...

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

A Comparison of Permeability Prediction Methods Using Core Analysis Data Permeability is one of the most important parameters of reservoir rocks, it illustrates the capacity of a rock to transmit fluids (oil, gas, water) in pore spaces. Permeability data can be obtained from routine core analysis in the laboratory on 1.5 in plugs and sidewall core. However, coring is limited due to the cost issue, so permeability prediction in uncored sections play a significantly important role. The variety of methods developed to estimate permeability using pore-scale such as Kozeny-Carman, Swanson, and Pittman. In fact, those equations are applied individually to estimate permeability. In this research, permeability estimation methods will be used on the same rock (sandstone or carbonate rock) to detect the suitable method for each rock type. Porosity, permeability data from routine core analysis and pore throat size from mercury injection capillary pressure on sandstone and carbonate rocks ...

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...

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...
