As generally known, subsurface pressure can be implied using both wireline logs and drilling events. However, there may a case where events do not indicate the same pressure. Data from four vertical wells located in South Sumatra Basin, Indonesia, were analyzed as study. Two wells, Wells A D, encountered high overpressured zones, confirmed by data. The two others, B C, only low inferred relativ...

Examples from the Polish clastic and carbonate reservoirs Central Anticlinorium, Carpathians Carpathian Foredeep are presented to illustrate possibilities of using well logging geothermal resources recognition characterization. Firstly, there was a short description selected logs methodology determination petrophysical parameters useful in investigations: porosity, permeability, fracturing, min...

The well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform is the eastern part of Central Indus Basin, and tectonically it is the stable portion of Indus Basin, which was least affected during Tertiary Himalayan orogeny. This study attempts to decipher reservoir potential for hydrocarbon exploration. It aims to delineate a subsurface hydrocarbon bearin...

Mechanical and chemical processes experienced by carbonate rocks result in a complex network of natural fractures dissolution features that have direct implications on porosity, permeability, connectivity reservoirs. Characterization is best done core; however, it can be time-consuming due to the large amounts individual present long list attributes typically collected for each feature. Additio...

The reservoir permeability (K) factor is the key parameter for characterization. This considered as a determinant quality index. Depending on data required and procedure availability, can be defined from several methods such as; well test interpretation, wireline formation tester, core data. These approaches also in assumption with prediction targeting non-cored sections. According to similar s...
