Resistivity measurements made while drilling have evolved from the simple short normal devices of the early 1980s to sophisticated multitransmitter and multielectrode devices of the 1990s. This article looks at the latest logging-while-drilling resistivity tools—the ARC5 Array Resistivity Compensated tool and RAB Resistivity-at-the-Bit tool—with applications ranging from invasion profiling to image and dip analysis.
