Accurate resistivity from multi-frequency compensated measurements.

Placing wells in the most productive zone requires understanding the fluids in the reservoir. The ResiStar service from Sperry Drilling provides multi-frequency, compensated measurements with downhole environmental corrections for accurate resistivity in all drilling environments. 

Enhanced resistivity measurements

The ResiStar service provides industry-leading resistivity measurements, building on the latest generation of downhole electronics and novel antenna designs used across our comprehensive range of resistivity services such as the EarthStar® Ultra-Deep Resistivity Service.

Accurate resistivity in all drilling environments 

The ResiStar service uses two frequencies and three compensated spacings, reducing borehole rugosity effects on the measurement quality. Significantly increased sensitivity combined with comprehensive environmental corrections deliver accurate measurements in all operating environments to cover the widest possible range of formations and provide input to advanced petrophysical analyses.

Precise reserves evaluation

Delivering highly accurate conventional resistivity measurements and enabling precise reserves evaluation and improved formation delineation and reservoir understanding.
