Wireline openhole logging

Advance your understanding to optimize reservoir performance

Your reservoir, in full geologic detail

The ground truth for high-resolution information to address reservoir complexity and to guide and constrain modeling is conventional whole core. But, it’s obviously not practical to core and analyze the entire drilled well. Nor is the resolution and confidence of what can be interpreted from seismic data alone sufficient.

The industry’s recognized approach for efficiently acquiring representative information is wireline openhole logging, deploying sensors to measure all aspects of the reservoir in situ and in real time.

Get the answers you need for informed decision making and risk reduction from precise and accurate downhole logging measurements, delivered workflow-ready for interpretation and refining your reservoir model.

Petrophysics

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.

Geology

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.

Geomechanics

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.

Reservoir Engineering

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.

Geophysics

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.
