: It measures the electrical conductivity of the earth, a foundational method for identifying oil-bearing zones versus water-saturated formations.
A compelling case study from a deepwater Gulf of Mexico well illustrates the tool's value. An operator faced major uncertainties about the type and distribution of sand bodies in an area of poor seismic resolution. By acquiring and interpreting Quanta Geo images, the customer was able, for the first time in an OBM environment, to like current ripples and shale clast imbrication. This information was used to refine the geological model and define a more accurate field appraisal strategy. schlumberger ngi tool
Modern SLB imaging tools are designed to provide a "visual" representation of the subsurface, even in challenging environments such as oil-based muds (OBM). : It measures the electrical conductivity of the
