These are old wells that were used for the extraction of gas or for the injection of waste water from the Drenthe oil extraction. The gas has been extracted from the ground and the locations are no longer suitable for waste water injection. The pit ‘Deurningen 1’ will start soon.
NAM dismantles the old drilling sites and seals them hermetically. Contaminants in the ground are remediated, the slab of asphalt is removed and the original owner then regains control of the soil. In most locations the land was leased from the owner.
‘No other uses’
“The wells are being removed at all these locations, because we do not see any other possibilities for use”, explains geologist Vincent van Engelen. Van Engelen is employed by NAM and coordinates the clearing of old wells. In this case, removal means that the pit is covered with concrete in a number of places deep in the soil.
At some locations, NAM is looking for useful reuse. For example, a large solar park is being constructed on the site of the old gas purification plant in Emmen. The existing electricity cables can be used for this, for example. For example, NAM is looking for a different interpretation in more places. Apart from the usefulness of reuse, this also saves on disposal costs.
The Nederlandse Aardolie Maatschappij will probably start clearing the first well next month.
What is certain is that the old NAM location in the Spingendal in Tubbergen will not be reused for another purpose after it has been dismantled. “That doesn’t seem sensible in such a valuable nature reserve,” says NAM geologist Van Engelen.
The area around the NAM location in the Springendal has already changed a lot in recent years. Remediation still needs to be done underneath the site, but NAM has already cleaned up significant soil contamination next to the extraction site. Staatsbosbeheer took the opportunity to cut old trees and build a frog pool.
