Abstract
The paper considers benefits of Wireline Formation Testing (WFT) enhanced applications to increase the field geophysical survey methods information content by using advanced pressure survey, downhole fluid analyses with sampling and interval testing including the assessment of reservoir hydrodynamic parameters (permeability, productivity, skin factor, etc.). The results present a comprehensive analysis of well logging data augmented withWFT to determine fluid level contacts and reservoirs saturation in the Lower Cretaceous deposits for a well drilled on Caspian Sea shelf. It was shown the possibility to identify potentially productive gas-saturated intervals by using well logging and WFT in conditions of reduced porosity and permeability properties. Discussed approach is also presented the way how to optimize well testing program through productivity evaluation using the WFT methods in orderto reduce the time for conducting hydrodynamic studies without loss of information content.
