Mapna Drilling Company (MDCO) is conducting an Engineering, Procurement, and Drilling (EPD) project for the drilling and completion of a new well, as well as the overhaul and completion of three existing wells in the Sarajeh Gas Field. This project is being carried out as a contractor for the Iranian Gas Engineering & Development Company (IGEDC).
The Sarajeh Gas Field is situated 130 kilometers south of Tehran, 40 kilometers southeast of Qom, and 40 kilometers north of Kashan, near the desert boundary. This active field produces gas and condensate from Member E of the Qom Formation, which dates back to the Oligocene and Miocene geological epochs. The Sarajeh field is an anticline oriented in a northwest-southeast direction, measuring 25 kilometers by 5 kilometers. Production at the site began on March 22, 1959, and the field’s reservoir was converted for gas storage on September 22, 2011
Sixteen (16) wells have been drilled so far and wells No. 3, 5, 8, 10, 11, 12, 13, and 15 are now active during production/injection cycles. The estimated initial in situ gas storage capacity of the field is 232 million standard cubic feet (MMM SCF).
The main goal of the project is to achieve a gas production rate of 15 MMSCFD during the winter season to address the country’s gas production deficit.
Directional drilling of the 12 ¼” hole section of well SJ-017 was successfully completed to a depth of 2,670 meters using advanced water-based mud (WBM). The casing running and cementing jobs were also finished successfully. A notable achievement in this hole section was the successful replacement of oil-based mud (OBM) with WBM, which resulted in no major drilling issues, cementing without loss and zero.
