The Distinguished Lecturer Program is one of SPE's most popular programs. Each season 30 to 35 experts from the oil and gas industry are selected to share their knowledge on the latest technologies and trends with SPE members. Established in 1961 with just three lecturers, the esteemed program now sends Distinguished Lecturers to SPE sections three times a year to give a total of more than 550 lectures all over the world. The purpose of the program is to provide SPE sections with outstanding speakers for section meetings, and to recognize the professional contributions of the selected Distinguished Lecturers. The program promotes SPE's mission to collect, disseminate, and exchange technical knowledge.
