Lithology and Fluid Prediction by Seismic Data Analysis
Idemitsu emphasizes that Lithology and Fluid Prediction based on Seismic Data Analysis is one of the most important areas to focus on. Idemitsu boosts up the implementation and improvement of the technology to increase in success ratio.
Look Inside
The seismic technique allows us, by analyzing the artificially shooting seismic waves that are reflected at the subsurface layers, to get a grasp of underground conditions. In the past, it was used just to obtain the shapes of subsurface geological structures. Recent advances in computer technologies, acquisition/processing techniques, and background theories enable us to evaluate the physical properties of the geological bodies themselves. Furthermore, the rock-physics theories with geological constraints will transform the evaluated properties to rock types and/or saturation fluids. Advancing our specialists with the cutting-edge technologies and installing the state-of-the-arts computer systems for the analysis and the visualization, we evolve the Lithology and Fluid Prediction by Seismic Data Analysis to our core technology.
R&D
Idemitsu geoscientists and engineers keep enriching their knowledge and skills in various research institutes and programs like “the mechanism to control the distribution of reservoir rocks” and “the sealing capacity of rocks and faults” to be competitive in the worldwide basis. Idemitsu continues to invest in our self-driven specialists to develop practical applications in innovative technologies. For geophysics side, recently our specialist has completed an advanced research study at Stanford Rock Physics Project: well known leading group in the quantitative seismic analysis. In the oil and gas industry, the acceleration of pace to invent new technologies rises the chance of new discoveries drastically. In this rapid change in the business environment, aspiring to enhance the presence as a technology-led company, Idemitsu keeps investing in and implementing the cutting-edge technologies to contribute to the new discoveries and top-up productions.
