Openhole Formation Evaluation
Gather valuable information to optimize reservoir performance
Our comprehensive portfolio of openhole wireline tools help guide your drilling, completion, stimulation, and production decisions for maximum recovery of reserves.
Detect variations in rock properties
Acoustic Logging Tools
Our acoustic logging tools provide measurements for anisotropy, permeability, fracture identification, depth/time conversion, and rock geomechanics.
Acquire representative fluid samples and precise PVT data
Fluid Testing and Sampling Tools
An advanced formation testing platform and an innovative, slim PVT sampler enable us to obtain pressures, determine fluid properties, and take samples from 3 to 14-in. hole sizes
Update your geological models with high-resolution logs
With a Compact™ microimager and oil-based imager, our geological tools deliver high-resolution data to assess faults, fractures, thin beds, dip angles, rock type, and rock quality.
Characterize rock and fluid properties
Lithology and Porosity Nuclear Tools
With direct or interpreted petrophysical characterization that includes 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.
Distinguish rock and fluid properties
With direct or interpreted petrophysical characterization of resistivity data, our resistivity tools help you to assess formation properties, bed thickness, lithologies, porosity, fluid type, as well as water and hydrocarbon saturation.
Measure well geometry
Our auxiliary logging tools provide measurements for well trajectory and borehole diameter logs.
The MTC tool orients and centralizes tool strings to produce borehole-diameter logs. It also provides powered centralization in situations where conventional centralizers cannot be used such as through-drillpipe logging.
