Equinor has played an important role in the last decade in the testing and development of
ultradeep azimuthal resistivity (UDAR) measurements both for look-ahead and look-around …

The recently introduced electromagnetic look-ahead (EMLA) tool applies deep-directional
resistivity logging-while-drilling technology for geostopping and other applications in vertical …

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 …

During hydraulic fracturing of low to moderate (0.1–50 md) permeability reservoirs using
crosslinked gel fluids, the final proppant stage displacement is designed to leave some …

The electromagnetic propagation (EMP) measurement frequently acquired with logging-
while-drilling (LWD) tools in high-angle wells is sensitive to geometrical effects that can …

Carbonate rocks are often characterized as containing complex porosity systems from
primary to secondary, and even intertwined multi-porous systems. Consequently, this …

Deep directional resistivity logging-while-drilling technology and its measurement
processing are instrumental in strategic well placement, landing, geosteering, and reservoir …

Stag field in the northwest shelf of offshore Australia has been in production since 1998 and
