However the MLA for East Antrim said lessons must be learnt, calling for tougher laws and the creation of an Independent Environment Protection Agency.
Stewart Dickson said: “News this unpopular drilling project has come to an end early, and without success, will be welcomed by the many who have campaigned tirelessly in the area.
“Since the project began I have consistently questioned the decisions that led to the drilling getting approval in the first place, including questioning the former Department of Environment over its granting permission for the drilling by default.
“This had the potential to unleash serious environmental consequences and we must ensure lessons are learnt.
“Self regulation does not work. Only the creation of an Independent Environment Protection Agency will allow the structures and laws to work effectively as intended.”
