ABSTRACT
With the current situation of Vietsovpetro joint venture, most of the fields have been exploited for a long time, especially the X field, the condition of the well after the exploitation stage has changed a lot, its reservoir property also different
To study the storage characteristics of the cased-hole wells, i use the method of measuring oil saturation behind casing (RAS) This method is a geophysical method using a pulsed neutron technique to determine oil saturation of the hydrocarbon reservoir behind the casing, including method Sigma and C/O (Carbon Oxygen Ratio) The application of RAS method is very important in the current stage, helping to provide optimal solutions such as choosing perforated intervals after a period of exploitation; assessing the potential reservoir as well as omitting the less promising reservoir, that helps save time and money The main object of the study
is the lower Miocene sediments of the X field, Vietsovpetro Joint Venture
