Reservoir Characterization

Advance your understanding to optimize reservoir performance

The better you understand your reservoir, the better positioned you are to optimize its lifetime performance. Understand your reservoir rocks and fluids through accurate measurements and characterization delivered by our tools, services, and petrotechnical expertise.


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.


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.


Rocks have a wide range of stiffness and strength and are exposed to variable stresses during drilling, completion, and production. Downhole acoustic measurements and laboratory core analysis provide input for geomechanical modeling to efficiently develop, produce, and ultimately abandon reservoirs.


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.

Logging Data Optimizes Eagle Ford Fracturing

The engineered completion design aligns the fracture stages and their perforation clusters with intervals of high reservoir quality and similar completion quality.
Engineered completions based on reservoir and completion quality determined from logging data improve the average perforation efficiency by 28% over conventional geometric spacing to increase NPV in the first year by USD 1.5 million. Read case study
