===Research Laboratory===
From the 1960s, until the end of the twentieth century, ARCO operated a highly significant research and development center in Plano, Texas, on land purchased in 1964 by the Atlantic Refinery Company.<ref>{{cite web |url=https://www.plano.gov/DocumentCenter/View/1201/Plano-Time-Line?bidId= |title=Plano city Timeline |work=City of Plano |pages=19–20 |archive-url=https://web.archive.org/web/20200726090551/https://www.plano.gov/DocumentCenter/View/1201/Plano-Time-Line?bidId= |archive-date=2020-07-26 |url-status=dead}}</ref> Its golden age was arguably in the early to mid 1980s, when it was led by [[Robert L. Hirsch]].  A standout example of ARCO's research at that time was the pioneering study on 4D seismic surveying by Robert Greaves and Terry Fulp.  This consisted of repeated 3D seismic surveys which successfully mapped the effects of enhanced oil recovery processes as a function of time.<ref>{{cite journal |last1=Greaves |first1=Robert |first2=Terrance J. |last2=Fulp |year=1987 |title=Three-dimensional seismic monitoring of an enhanced oil recovery process |journal=[[Geophysics (journal)|Geophysics]] |volume=52 |issue=9 |pages=1175–1187 |doi=10.1190/1.1442381|bibcode=1987Geop...52.1175G }}</ref> This work was recognized for its seminal importance over 20 years later by the [[Society of Exploration Geophysicists]].<ref>{{cite web |url=https://wiki.seg.org/wiki/Virgil_Kauffman_Gold_Medal |title=Virgil Kauffman Gold Medal |work=[[Society of Exploration Geophysicists]]}}</ref>{{Failed verification|date=April 2021|reason=How does this citation support this statement?}}  Besides Greaves and Fulp, the laboratory produced a number of other distinguished alumni during this golden age, including scientists [[John Castagna]], Michael Batzle, Geoffrey Dorn, and [[Marius Vassiliou]].  In later years the laboratory experienced significant contraction. It finally closed shortly after the 2000 acquisition of ARCO by BP.
