Distinguished Technical Achievement

Teruhiko (Terry) Hagiwara

Terry joined Petrophysics group at Bellaire Research Center of Shell Oil Company in 1981. From 1993 to 2001, he was Technology Advisor at Houston Technology Center of Halliburton Energy Services. He is currently a full-time consultant to Shell International Exploration & Production at Bellaire Technology Center. Terry received his BS in Physics and MS in Experimental Nuclear Physics from University of Tokyo, Japan, and his Ph.D. in Theoretical Physics from SUNY at Stony Brook.

While at Shell Oil, he pioneered “parallel conductance” and “macroscopic anisotropy” models to evaluate thinly laminated binary formations. He pioneered electromagnetic tool modeling to solve borehole environmental log interpretation problems. He started “deep logging” project profiling anomalies including salt domes and bypassed reservoirs. He started in-house nuclear log modeling project using MCNP Nuclear Transport simulation code. Rock physics has been also his interest: he examined electric conductivity – flow permeability relation and their anisotropy model and studied various rock models to understand mixing laws.

While at Halliburton, he was involved in development of many electromagnetic logging tools. He pioneered methods to utilize anisotropy for more accurate formation evaluation; identified anisotropy effect on LWD resistivity tool responses; developed methods to measure anisotropy in vertical wells using galvanic and induction–type measurements. He proposed directional LWD resistivity tool for better geosteering in offshore horizontal drilling. He was a key member in development of formation compaction monitoring tool.

Most currently at Shell he is working in deep-reading electromagnetic logging project that has produced many new promising geosteering and formation evaluation techniques (and, hopefully, will generate more).

Together with H.M. Wang of Schlumberger, he chaired Resistivity and LWD SIG for 2002-2004.

Terry’s broad interest in many areas of petrophysics and logging technology, in particular electromagnetic methods, led to many other modeling and interpretation innovations which formed the basis for his 16 U.S. patents and his 35+ publications and presentations.

Terry is also an accomplished Ceramic Artist.
