Dr. Qalavand said: In order to implement development plan of the field, fifteen developmental wells including 12 horizontal and 3 vertical wells were drilled and by installation of pump inside the wellbores, oil extraction from the field increased from 3 to 28 thousand barrels a day.  

‘In recent 100 years about 20 percent of in place oil reserves of Masjed Solaiman oil field has been extracted’, NISOC’s managing director noted.

The executive added: given geological structure of the oil field, there is the possibility to extract another 4 to 5 percent of oil from the field by applying secondary methods including using wellbore’s pumps and desalination equipments.

Qalavand stressed that using pump as a secondary method to improve recovery rate is a new experience that could be applied for development and revival of those oil fields which their oil yielding is falling due to low level of pressure.
