Paper presented at the SPWLA 64th Annual Logging Symposium, June 10–14, 2023
Paper Number: SPWLA-2023-0082
... ABSTRACT Logging-while-drilling (LWD) ultra-deep azimuthal resistivity (UDAR) tools became an essential part of well placement technology because they are deep enough to explore the reservoir as a whole and map it in a similar scale with seismic sections. Due to the large formation volume...

... and important events in the life of the wells. A first finding is that differences in apparent CO2 saturation between the various independent measurement physics of the pulsed-neutron tool are often reconcilable and may carry additional information about the state of the well or reservoir. With respect...

.... In this paper, the authors will review the use of UDAR in Equinor the last decade and highlight both successful use and real-time challenges related to interpretation of the inversion results. UDAR-technology and inversion algorithms have been very powerful for reservoir mapping to geosteer or geostop according...

Paper Number: SPWLA-2021-0043
... Abstract In recent years, the development of frontier areas brings added challenges to formation evaluation, especially thinly bedded reservoirs. It is challenging to evaluate such reservoirs due to the low resistivity values and high shale volume, which masks the contrast between water...

Paper Number: SPWLA-2021-0075
... Abstract Relative permeability is one of the most important petrophysical parameters to evaluate a reservoir’s production during primary and subsequent secondary or enhanced oil recovery processes. Yet measured relative permeability data for tight oil reservoirs are very scarce to find...

Paper Number: SPWLA-2021-0021
... Abstract Pulsed neutron carbon-oxygen (C/O) logging is a valuable measurement for dynamic reservoir saturation monitoring, especially in mixed salinity and fresh-water environments. Currently, all C/O logs are based on apparent C/O measurements, thus responses of raw data are not comparable...

The cost-effective formation evaluation technique described in this paper allows rapid identification of dynamic heterogeneities along the reservoir after the drilling of a horizontal well. This key information then can be used...
