Openhole Wireline
Gather valuable information to optimize reservoir performance
Our comprehensive portfolio of openhole wireline technologies, along with expert logging interpretation, help guide your drilling, completion, stimulation, and production decisions for maximum recovery of reserves.
Characterize rock and fluid properties
Petrophysical Services
With direct or interpreted petrophysical characterization that includes resistivity, nuclear density, and nuclear porosity data, we can help you to assess formation properties, bed thickness, lithologies, porosity, fluid type, as well as water and hydrocarbon saturation.
