Geosteering with logging while drilling (LWD) represents the state of the art in directional drilling technology. However, the current China LWD dataset is dominated by non-azimuth gamma ray and resistivity measurements, leading to uncertainty in geosteering results. Consequently, the full use of LWD, logging and drilling data to evaluate and interpret drilled formations in real time becomes a beneficial means to overcome the disadvantages of using LWD data alone. This study presents the technology for integrated 3D and 2D visualization of LWD data, logging and drilling, and presents a method for their integrated use for reservoir assessment, reservoir modeling and geosteering. Practice has shown that the most complete and complex information based on the reservoir model and visualization methods is the key to improving the accuracy of reservoir modeling, optimizing the wellbore trajectory and increasing the drilling success rate. Thanks to active research into geosteering capabilities, reservoir assessment methods and technologies, appropriate software was developed and successfully applied in a number of oil fields, which ultimately increased the competitiveness of geosteering technologies of Chinese companies, balancing the technological level in comparison with multinational companies and breaking the monopoly on the formation of service prices.......
