Following four months of testing operations, Yangye 1HF flowed gas at a stabilized rate of 2.765 MMcfg/d (maximum flow rate of 6.05 MMcfg/d) from the Lower Cambrian Niutang Formation. The testing operations at Yangye 1HF commenced in late August 2017 following completion of a 33 stage fracture stimulation programme within the Lower Cambrian Niutitang Formation on 19 August 2017. Yangye 1HF was drilled to a TD of 5,179m MD with a horizontal section of 1,835.42m MD within the Niutitang Formation on 1 July 2017 and was suspended for fracture stimulation and testing. Vertical well Yangye 1 flowed gas to surface in March 2017 following a three stage fracture stimulation programme within the Doushantou Formation from 20-31 January 2017. Yangye 1 was drilled to a TD of 3,501m MD and was suspended for further evaluation on 30 September 2016 after having been spudded on 6 May 2016. The well was deepened below the PTD of 3,230m due to strong oil and gas shows being observed within the Doushantou Formation between 3,328-3,440m. Approximately 50m of strong oil and gas shows were also encountered while drilling in the target Niutitang Formation. The shale gas exploration/stratigraphic well had a PTD of 3,230m and was targeting the Lower Cambrian Niutitang Formation and Lower Sinian Doushantuo Formation with the objectives of collecting shale gas data on the reservoir characteristic and potential shale gas reserve in the area. Yangye 1 is in Hubei Province, Yichang City, Changyang County, Hejiaping Town. <P />
