Petroleum exploration works began in Ottoman Empire in 1887. The works began firstly in Cengen, Alexandria, continued with the works done in Mürefte, Tekirdag. Important developments about petrol of Mosul and Kirkuk also took place. Petrol investigations that Ottoman Empire had maintained until 1914 were interrupted with the outbreak of World War I.
With the geologic surveys in the Republic period, again, petrol explorations were carried out in Tekirdağ - Mürefte, Midyat - Basbirin, Midyat - Hermis, Hayrabolu - Kabahöyük, Muradiye - Kürzot, Adana - Hoca Ali, Arsuz - Ekver and Siirt-Raman. The first promising petrol in Turkey was discovered in Raman.
With the discovery of petrol in Raman, there appeared a compulsory situation to establish a refinery. The first step for the refinery was taken in 1940 in Raman or Maymune Defile Experience Refinery. The attempts to establish Batman Experience Refinery followed this work.
Opening of efficient and economical petrol wells in Raman and Garzan started the works on the establishment of Batman Modern Refinery. For Batman Modern Refinery, planned to be built in 1953, two Companies from the USA, The Ralph M. Parsons Company and Koch Engineering Company, gave an offer.
The Ralph M. Parsons Company won the refinery tender. Batman Modern Refinery has continued its activity to provide a portion of the needs, gasoline, diesel and asphalt, of Turkey.
