Abstract

Diese Studie behandelt die Wassereinpressung im Rahmen eines Pilotprojektes in der drittgrößten Lagerstätte des Matzener Feldes 8. Torton (Produktionseinheit 208-10-15). OMV AG führt ein periphäres Wasserflutungsprogramm in der antiklinalen Struktur des 8. Torton durch. Die Wassereinpressung wurde 1961 in dieser Produktionseinheit begonnen. Aufgrund der relativ schlechten geologischen und technischen Bedingungen wurde beschlossen, dieses Projekt durchzuführen, da die zukünftigen Optionen für primäre Förderung beschränkt sind. Wegen der hohen durchschnitlichen Verwässerung und der Heterogenität der Lagerstätte wurde die Produktionssonde S124 im September 2000 in eine Injektionssonde umgewandelt. Nach einer umfassenden Analyse der wesentlichen Parameter, wie Verwässerungsgrad, Salinität des Wassers, dynamischer Flüssigkeitsspiegel und Förderverlauf von 26 Produktionssonden in der Umgebung der betreffenden Zone, konnten jene Sonden, die von der Wasserflutung beinflusst wurden, bestimmt werden. Deren Produktionsänderungen waren Grundlage für die wirtschaftliche Bewertung des Pilotprojektes.
