Commencement of Production from Development Well ZS-3

MPCL has put on production recently drilled development well ZS-3 in Zarghun South Gas Field (Bolan Block), Balochistan.

ZS-3 is the first ever highly slant well drilled by the Company using its own Rig and expertise. The well was spud-in on September 20, 2016 (10 days earlier than planned) and reached TD of 1820 m (MD) / 1649 m (TVD) on November 20, 2016. MPCL’s own Rig Mari-1 was deployed for the drilling.

After completion, the well flowed 4.772 MMSCFD gas with 1,013 psi WHFP at 28/64” fixed choke, before acid job. Post-acid, the gas flow improved to 8.691 MMSCFD with 1,785 psi WHFP at the same choke size. Gas flow will further improve with increase in choke size. The raw gas produced from the well is of superior quality with heating value of approximately 930 Btu/scf.

After hook up with central processing facilities, the gas is being injected into SSGCL’s network. The well will enhance field production to meet committed gas supply to SSGCL for Quetta City.

The gas produced from ZS-3 will be eligible for tight gas price of USD 4.7979/MMBTU compared with normal price of USD 2.8182/MMBTU.
