3D radial probe
Perform formation testing where previously not possible.
A major operator in Brazil successfully deployed the large-hole version of the 3-D radial probe to determine the oil/water contact in a 12 1/4-in. deepwater well in a presalt carbonate formation. The probe can sample and take pressure tests quickly with minimal drawdown on the reservoir over a total surface flow area of nearly 80 sq. in., expanding the operational envelope of formation testing more than 40 times over the largest conventional probe.
Limit pressure drawdown during fluid extraction and sampling to obtain critical data for optimized well tests and facility design.
Increase the length scale by obtaining permeability and anisotropy away from the wellbore to better understand reservoir heterogeneity.
