The Beginning of His Academic Journey
His passion for petroleum engineering began at the Petroleum Engineering Department of ITB, where he earned his bachelor’s degree in 1975. He then continued his studies in France and obtained a Diplôme d’Études Approfondies (DEA) from Université Paul Sabatier, Toulouse (1978), in the field of Porous Media Mechanics. Not stopping there, he pursued a doctoral degree at Université de Bordeaux I, Talence (1980), with a dissertation on polymer flow studies for EOR applications—research that became a significant foundation in the development of Enhanced Oil Recovery.
Dedication to Education
Upon returning to Indonesia, Mas Septo—as he is fondly called—resumed his service as a faculty member at Petroleum Engineering ITB until 2021. He taught courses such as Enhanced Oil Recovery, Immiscible Displacement, Chemical Flooding, and Advanced Optimization Techniques.
In addition to teaching, he served as Department Secretary (1986–1989), Deputy Head of the Research Center (1999–2002), Head of the Petroleum Reservoir Engineering Research Group (2006–2015), and led the OPPINET research consortium (2001–2021) as well as OGRINDO (2004–2021).
Pioneer in Research and Innovation
Mas Septo initiated two major research consortia at ITB: Optimization of Pipeline Network (OPPINET) and Oil and Gas Recovery for Indonesia (OGRINDO). Both programs became bridges of collaboration between academia and industry, delivering EOR technologies ready to be applied in the field.
His research and consultancy covered various oil and gas projects in Indonesia, from Minas Field (Riau), Handil and Bunyu (Kalimantan), Arjuna Offshore (West Java), to Tiaka (Sulawesi).
Role in Industry and Organizations
Since 1975, he has been involved in various industrial projects and consultancy works, for Pertamina, foreign oil and gas contractors, as well as research institutions such as PPPTMGB LEMIGAS. He was also a member of the BPMIGAS Technical Advisory Committee for the surfactant EOR project in Minas Field alongside professors from Texas, USA. His reputation has made him frequently invited as a speaker in numerous strategic discussions in the oil and gas sector.
He has been a member of the Society of Petroleum Engineers (SPE) since 1975 and has been active in various other professional organizations, including IATMI and IPA.
Now, although retired from ITB, Prof. Dr. Ir. Hasian P. Septoratno Siregar, DEA, remains actively driving innovation through OGRINDO ITB and various industry collaborations. With his dedication and experience, he continues to inspire the younger generation of petroleum engineers to advance Enhanced Oil Recoverytechnology for the nation’s energy independence.
