Measurements at scales from pores to sedimentary basins are analyzed and interpreted to develop micro - and macrogeological models. Knowledge of local and field-wide structure and variability helps to achieve optimal reservoir contact and guide well paths to avoid hazards.
Formation evaluation characterizes rock and fluid properties based on downhole measurements, formation testing, and laboratory analysis services. Petrophysical analysis using a wide variety of measurements leads to an understanding of the reservoir and its detailed characteristics.
Large-scale sensing finds reservoirs in all types of environments, providing the basis for a 3D reservoir model with physical properties at all scales. Geophysics provides the “big picture,” while wellbore-scale seismic and petrophysical data deliver formation understanding in detail.
Reservoir engineering provides an understanding of fluid flow and phase behavior at all scales, for all fluids, and in all geological settings. Formation pressure measurement, downhole fluid sampling and analysis, and laboratory PVT analysis are used to build a picture of reservoir potential and predict future performance.
