Lithological Identification and Prediction of Volcanic Rock

Lithology consists of characteristics such as rock color, composition, texture, and structure. For volcanic reservoirs, lithology is one of the factors that control reservoir space and other properties. Based on the schemes of rock classification and nomenclature, volcanic lithology can be identified according to logging identification models for composition, texture, and the structure of various types of volcanic rocks, and by integrating elemental capture spectroscopy (ECS) element logging, acoustic, and electric image logging and conventional logging. Through calibration of seismic data based on well logs and analysis of seismic responses of different lithologies, volcanic ...
