Fractured Tight Sandstone
Using empirical studies tight sandstone reservoir in the Cuu Long Basin - Vietnam, Clastic Fracture module has been being developed to optimize the process of data interpretation in the reservoir petrophysic this.
Multi mineral solver
Understanding lithology is key to evaluating a complex formation because it directly influences the porosity distribution in the rock and the geomechanical properties of the formation. From logs data and another information such as petrography,mud logging, etc. you can build rapid, robust models that explain complex mineralogy and porosity in formation
Calculate and Correct Secondary Porosity
The fracture-vug system mainly formed by tectonic activities includes some systems of intersecting directional faults and vug system developing along the macrofracture surfaces, widens or joins them, (???) has been formed in the process of rock formation and in the process of hydrothermal activities. The fracture - vug systems are characterized by hydrodynamic permeability. Fractured sandstones and shale could be considered as reservoir.
In-tergranular pores of fractured sandstones could contribute to increasing of an accumulation ability of reservoir if its secondary porosity is bigger than cut-off value Φ*.
In-tergranular pores of unfractured sandstones could contribute to increasing of an accumulation ability of reservoir if its total porosity is bigger than cut-off value Φ**.
Cut-off value Φ* is porosity, corresponding with which permeability of fractured sandstones is equal or bigger than its cut-off value of permeability.
