Achyut K.
Phansalkar
Jun 25, 1928 — Nov 2, 2026
Stillwater
Born on June 25, 1928, in Pune, India to Keshav H. and Radha (Athalye), Achyut K.
(Raj) Phansalkar was the 4 th of six children. He graduated top of his class from SP
College in Pune (1948), completed his BSc Tech/post-graduate work at the University of
Bombay and earned his doctorate in Chemical Engineering at the University of
Southern California as a Lever Brothers Fellow. In 1955, he began a distinguished 35-
year career at Conoco.
Raj married Tara Deo on April 20, 1952, in Pune, India. Following his PhD, they
relocated to Ponca City, OK. Raj became a recognized leader in underwater oil
exploration traveling the world on international assignments. Named a Distinguished
Lecturer by the Society of Petroleum Engineers, he frequently shared his expertise
globally until his retirement in 1991.
Upon retirement, Raj and Tara returned to Ponca City, where Raj became deeply
involved in the community. He was a dedicated member of the Rotary Club, recognized
as a multiple-time Paul Harris Fellow, and served on the boards of the Cherokee Strip
Credit Union, the Community Affairs Council, and Partners in Education. Adventurous
and curious, Raj and Tara traveled extensively across six continents and all 50 states.
Raj was an avid reader who loved exploring new cultures, business, and technology,
even testing his entrepreneurial spirit by successfully running a local travel agency for
four years.
In 2020, Raj and Tara moved to Primrose Retirement Community in Stillwater, OK. A
sharp-minded cancer survivor at 89, Raj deeply loved spending time with visiting family
and friends, sharing his humor and sage wisdom until his passing.
Raj is survived by his loving wife, Tara; his children, Nina (John Weaver) and Kiran
(Rebecca); his grandchildren, Alyssa and Roman (fiancé, Madeline Loosen); his sister-
in-law, Meera Phansalkar and numerous nieces and nephews. He was preceded in
death by his parents and siblings.
The family extends their heartfelt thanks to the doctors and staff at the Stillwater
Medical Center, Stillwater Cancer Center, Stillwater Medical At Home Hospice, and
Cornerstone Caregiving for their exceptional kindness and care of Raj.
Per Raj’s wishes, there will be no memorial service. A celebration of life for family will
be held later. Those wishing to honor Raj, may donate to the 9/11 charity, Tunnel to
Towers Foundation at: www.T2T.org
