PORTRAYAL (CHARACTERIZATION) OF LITHOLOGICAL PROPERTIES BY USING SELF POTENTIAL LOG AND GAMMA RAY LOG

Petroleum Engineering

The petrophysical assessment and lithological chacterisation of the Formation are practiced dependent on the anylysis of well logs. lithology is utilized as a gross recognizable proof for a stone layer in the subsurface and utilizations well-known names, for example, Sandstone (sand), Limestone, Dolostone (dolomite) ,Claystone (dirt), Chert, Coal, Shale (mudrock), Diatomite, Halite, Anhydrite, Gypsum, Tuff. The recognizable proof of a bed's lithology is key to all repository portrayal on the grounds that the physical and substance properties of the stone that holds hydrocarbons or potentially water influence the reaction of each instrument used to quantify arrangement properties. To make precise petrophysical estimations of porosity, water immersion (Sw), and penetrability, the different lithologies of the store interim must be recognized and their suggestions comprehended. To decide all components of the lithology well log examination is significant. Well logs give a for all intents and purposes persistent study of the arrangements crossed by a well. The report contains every one of the techniques utilized for lithological examination by well logs.
