During testing, the well is reported to have flowed 18.5 MMcfg/d through 44/64â choke at a well head flowing pressure of 1,916 psi between 3,833.6 m to 3,853.7 m (12,578 to 12, 644 ft) perforated interval within the Cretaceous Lower Basal Sand unit of Lower Goru Formation. It also flowed 54 bw/d during testing. Unarpur 1 was drilled to a TD of 3,938 m and testing was carried out from early February to late March 2019 after setting a 7â liner.  The well was spudded on 2 November 2018 using the âHL-5â land rig with a prognosed TD of 4,358 m in the Cretaceous and it was targeting the Lower Basal Sand unit of Lower Goru Formation. A sidetrack was initiated in mid-November 2018 after drilling to 3,191 m depth and the well had reached 3,846 m depth by the end of December 2018. Kotri North EL, which covers an area of 2,472 sq km, is located in the Sindh province and current equity split is as follows: UEPL (60%, operator) and Pakistan Petroleum Ltd (PPL) (40%).
