Spectral characterization of Kolsuz-Ulukisla-Nigde clays, Central Anatolian Region-Turkey and petroleum exploration

  Characterization of the Kolsuz clays in the Central Anatolian Region (Ulukisla-Nigde-Turkey) were carried out using the spectroscopic techniques and results were interpreted in terms of petroleum exploration. The DTA-TGA measurements have been carried out for determinations of thermal behaviour of the clay samples. The FTIR spectra of clays known as standard clays such as illite, illite-smectite mixed layer,...

Saturation and pressure distributions in a two-phase flow through semi-infinite porous media

  This paper presents models and solutions for the saturation and pressure distributions in a two-phase flow through semi-infinite porous media. The mathematical model, which was developed from the popular Darcy’s equation and the continuity equation, contains a substance source/sink term. The implicit finite difference formulation of the model was solved for saturation and pressure using the modified...
