The seismic surveys by the Iraqi petroleum Company in 1956 for the Sufaiya area showed theexistence of a geophysical phenomenon extending northwest-southeast, followed several seismicsurveys in that area which confirmed the presence of a geological structure in that area. Then,other seismic surveys were carried out to clarify the structural side of the field includes thesurvey of the Bulgarian Techno export Company 1977.The exploration well Sufaiya -1 was drilled in 1973 and the drilling reached the depth 3504meters from Rotary Table Kelly Bushing. The oil appeared in the Gir Bir, Mushorah andShiranish Formations, produced gas and condensate in the Karra Chine formation. In the light ofthis promising information and information obtained from the seismic surveys and drilling wellsin the structure. The drilling wells continued in this structure until to reach the number of wellsin the Sfaiya area 47 wells, including 5 wells penetrating the Gir Bir reservoir completely, whichis Sfaiya - 1, 2, 4, 12 and 29.
