In the development of a reservoir, it is critical to know the hydrocarbon saturation, which
generally requires reliable horizontal and vertical formation resistivities. In recent years …

Detection and quantification of formation resistivity anisotropy is important in many
reservoirs, particularly those with laminations thinner than the axial resolution of standard …

Resistivity measurements have been used in the oil and gas exploration and production
industry for many decades to provide valuable information relating to the determination of …

A new logging-while-drilling (LWD technology has been developed and field-tested that
introduces directional electromagnetic (EM measurements through the use of tilted and …

Over the last two decades, the continuing integration of distance-to-boundary logging while
drilling (LWD) workflows with the directional drilling processes, has dramatically improved …

Although the directional sensitivity and deep investigation depths of directional logging-
whiledrilling (LWD) resistivity tools have led to their wide use in detecting bed boundaries for …

Abstract Logging-while-drilling (LWD) electromagnetic (EM) propagation measurements and
interpretation techniques have been widely used for reservoir boundary detection in …

We present sensitivities of first generation of directional loggin-while-drilling electromagnetic
measurements using tilted and tasverse antenae technology. These measurements are …
