NAM have discovered gas in the Spijkenisse-Intra prospect that was drilled by the Spijkenisse Oost-4 exploration well in the Botlek III licence. According to NAM's work schedule, if the discovery contains sufficient gas volumes the discovery well could be put into production at the end of April 2020. On 13 March 2020 NAM spudded the Spijkenisse Oost-4 exploration well and the drilling operations were complete on 13 April 2020. The DrillTec "Synergy II" rig was used for the work. Spijkenisse-Intra is a small tilted fault block between the producing Spijkenisse-Oost and the suspended Spijkenisse West gas fields. The well was deviated to the southwest from the Spijkenisse Oost well pad to target gas in the Triassic Bunter Sandstone Formation that is prognosed at approximately 2,540 m TVD. The prospect has an estimated free water level at 2,590 m TVD and, unlike Spijkenisse-Oost and Spijkenisse-West, an oil leg is not expected. Production was forecast to commence in 2019 and continue until 2026 in the high case or until 2021 in the mid case. The high case recoverable gas forecast is 8 Bcfg.   Spijkenisse Oost was discovered in 1990 by exploration well Spijkenisse Oost ST1 and it was brought onstream in October 2006. The field has a gas column and a short oil column in the Upper and Middle Bunter Sandstone Formations. The crest of the structure at Upper Bunter Sandstone level is at approximately 2,400 m TVDSS with the GOC at 2,474 m TVDSS and the FWL at 2,482 m TVDSS. In 2013 it was forecast that the field would produce until 2020 in the mid case.  Spijkenisse West was discovered in 1992 by Spijkenisse West 1, which is approximately 4 km west from the Spijkenisse Oost discovery well. The field was producing gas through the Spijkenisse Oost-3 well from 2006 until 2016. The field contains gas and a short oil column in the Middle and Upper Bunter Sandstone reservoir. The Upper Bunter Sandstone crest is interpreted at 2,498 m TVDSS, the GOC is at 2,590 m TVDSS and the FWL at 2,597 m TVDSS.   The Botlek III licence is held by NAM (50% + operator) and Energie Beheer Nederland BV (50%).
