ABSTRACT:
Rdeep (Deep Resistivity) is an outdated concept that has been relevant for focused wireline measurements when invasion is the main environmental effect to worry about. Unfortunately, this concept is still very much in use in operating companies when petrophysicsits select just one resistivity curve to use in their petrophysical workflows and water saturation calculations. Currently, Rdeep usually means the apparent resistivity curve which is the least affected by environmental effects and closest to Rt, but selecting Rdeep could be tricky especially from unfocused LWD resistivity curves because: a. different environmental effects affect different curves differently; b. several environmental effects may affect simultaneously; c. in the same well different curves should be selected as Rdeep in different sections. The best way to understand environmental effects and correct for them or/and select Rdeep if absolutely necessary is to use resistivity modeling and inversion. Ultimately, we recommend using Rt instead of Rdeep.
BIOGRAPHY:
Michael Rabinovich is a Principal Subject Matter Expert in Resistivity Logging and Geosteering at bp Central team. Before joining bp in 2012, he was with Baker Hughes for 18 years as a scientist, Sr. Manager of Computational Physics group, and later as Deputy Director of Research of Drilling and Evaluation. He received his Msc degree in 1983 from the Moscow Institute of Oil and Gas industry and his PhD degree in 1989 from the Russian Academy of Science, both in Geophysics. He is an author/coauthor of more than 100 publications and 44 patents.
