The term ''difficult lithologies'', as addressed here, refers to a formation composed of two or more mineralogies. The presence of two or more minerals significantly increases the difficulty of determining both [[porosity]] and lithology from wireline logs. This article reviews some common techniques that can be used to solve for lithology and porosity. It also addresses some commonly encountered lithologies and their characteristics relative to log responses.
