| description | The present research is aimed at exploring the B1.1 sandstone sequence located in the lower Miocene formation within the Bao Den oilfield situated in the Cuu Long basin. This study involves utilizing Pressure-Volume-Temperature well parameters, such as bubble pressure, oil gas ratio, oil formation volume coefficient, density, viscosity, total compressibility, and BI.1 sandstone sequence parameter, including effective thickness, average porosity, well radius, and water saturation. Our focus will be on analyzing reservoir tests with two methods - the conventional and progressive approaches. This study will examine the Horner graph and how it can be used with formulas for determining initial reservoir pressure, slope, and fluid conductivity as part of the traditional method. Additionally, effective permeability, skin coefficient, and conductivity will also be analyzed. The advanced method involves using Ecrin software to interpret results, which shows that both methods yield favorable skin coefficients. The outcomes indicate that the well and reservoir parameters are precisely determined: the initial pressure of the reservoir is 2617.5 psia, hydro conductivity equals 7680 mD.ft, while permeability is 106 mD, coefficient Skin is 14, well storage coefficient evaluates to 5.61E-4 and distance to fault 439 ft. Based on the results, it is possible to assess that the BD-1X well in the Bao Den oilfield has promising potential as both oil and gas have favorable quality and volume attributes. This study's significance is providing input data for developing and exploiting oil fields resulting in choosing economical plans with commercial efficiency within the petroleum industry. |
