Logging-while-drilling and measurements-after-drilling services in all well types are handled by newly released WPR wave propagation resistivity tools.
They are compensated-geometry, dual-frequency (400 kHz and 2 MHz), dual-spacing formation evaluation designs. WPR features central receive antennas to deliver direct, real-time spatial compensation to eliminate errors due to mud invasion between measurements, borehole rugosity, and receiver channel differences, notes its manufacturer. WPR operates in all mud types including oil-base and salt-saturated. It delivers real-time resistivity with flexible transmission formats.
Among WPR applications: geosteering, correlation, pore pressure trend analysis, casing point selection, wireline replacement, logging while tripping and logging with / without the flow switch enabled (for air and foam-drilled wells). Complete wave propagation resistivity tools data are yours free.
