Project Profile
Location: Lower Indus basin onshore southern Pakistan
Area: 1,265 square kilometre
Start-up year: 2017
Petroleum Exploration has spudded an exploration well on the Ayesa prospect in the Lower Indus basin onshore southern Pakistan. The Badin IV South block probe would be drilled to a depth of 2,400 metres to target upper sands of the Cretaceous Lower Goru formation. The explorers secured a Dewan Drilling 900 HP rig in November 2013 to drill the probe along with the Haleema exploration well on the same block in Sindh province. The 1,265 square kilometre licence is situated near several producing oil and gas fields. In February 2016, Jura Energy made a new gas discovery at the Aminah-1 exploration well in the Badin IV South block.
Aminah-1 exploration well
Drilling commenced on January 06, 2016 and it reached the targeted depth of 2297 m. The well was logged and completed in the Lower Goru \'A\' Sands of Cretaceous age. Post-completion surface well testing was conducted in July 2016 after selective perforations of 14 m in the Lower Goru A-Sand. During a 10-hour test on 48/64 inch fixed choke, the well flowed gas at an average rate of approx. 19 MMcf/d with an average wellhead flowing pressure of 1,607 psi and having an average heating value of approx. 1,000 Btu/Scf. The average condensate to gas ratio was approx. 3.8 bbl/MMcf with the water rate of 24.5 bpd.
Ayesha North-1 exploration well
The drilling commenced on March 25, 2016 and it reached the target depth of 2,820 m. The well was logged and completed in the Lower Goru \'A\' Sands of Cretaceous age. Post-completion surface well testing was conducted in July 2016 after perforating 18 m interval in the Lower Goru A-Sand. During an 8-hour test on 48/64 inch fixed choke, the well flowed gas at an average rate of approx. 8.7 MMcf/d with an average wellhead flowing pressure of 771 psi and having an average heating value of approx. 970 Btu/Scf. The average condensate to gas ratio was approx. 8.17 bbl/MMcf with water rate of 28 bpd. The gas rate and wellhead pressures are expected to improve after planned stimulation to remove the formation damage.
