Independent Oil and Gas plc (IOG) spudded appraisal well 48/24b-6 on the Harvey discovery in licence P2085 on 6 August 2019. The appraisal well was to clarify the up-dip potential of the Harvey structure and had a 63% geological chance of success. It is being drilled with the Maersk âResilientâ (J/U) rig and operations were expected to last for 60 days. On 11 September 2019 IOG announced that the well has reached a TD of 7,537 ft (2,297 m) in the Permian Leman sandstone reservoir. The top of the Leman sands was encountered at 7,086 ft (2,160 m). Initial analysis indicate that a 49 ft (15 m) gas column has been encountered. Wireline data and core samples will now be fully analysed to better understand gas volumes and potential deliverability. Harvey could be developed via the Thames pipeline export route if deemed commercial. The rig left location on 19 September 2019.   Harvey is thought to hold minimum unrisked prospective gas resources of low case 85 Bcf, mid case 129 Bcf and high case of 199 Bcf. Currently IOG estimates that most likely 90 Bcf lies on its licensed acreage and in the case of a positive well result the company would request the OGA determine the Harvey licence area to include the full structure. IOG would try to fast-track the development of Harvey through exporting the gas via the newly recommissioned Thames pipeline.  Interest in licence P2085 is held solely by IOG North Sea Limited. However, in an announcement from 26 July 2019 it was stated that CalEnergy Resources Limited has an option to acquire a 50% interest in the Harvey acreage within three months of the completion of the appraisal well.
