On 14 July 2017 Vermilion started sidetracked exploration well Eesveen 2 in the Steenwijk licence after permanently abandoning the lower part of the Eesveen 1 well using DrillTecâs âExplorer TB 2100Sâ rig. It is believed that the well found gas at Eesveen North. The well encountered 24 m of net pay in two separate intervals in Zechstein carbonates and Rotliegend sandstones. The two zones were flow tested at a combined rate in excess of 1,800 Mcfg/d. The operations were completed on 17 August 2017. Vermilion started production from its Eesveen gas field which straddles the Steenwijk and Drenthe VI concessions in April 2015. Initial treatment (separation of the gas and condensate from water) takes place at the Eesveen location and then the well stream is piped to the Garijp processing facility. Eesveen was discovered in 1986 and it has a Rotliegendes Slochteren Sandstone reservoir, approximately 23 m thick with a GWC at 2,045 m TVDSS. A test carried out at that time by operator NAM concluded that the discovery was uneconomic. However, in 2005 Vermilion re-tested the well (Eesveen-1) and these results, together with new 3D seismic acquired later, led to the development of the field. Vermilion is expecting to recover 75% of the gas in place over a period of 2-5 years. Interest in the Steenwijk permit is held by Vermilion Oil & Gas Netherlands BV (50% + operator) and Energie Beheer Nederland BV (50%). Â
