Geotechnical challenges at Adriatic offshore gas platforms Subsidence due to exploitation at the Izabela Exploitation Field

Geotechnical challenges at Adriatic offshore gas platforms Subsidence due to exploitation at the Izabela Exploitation Field

The “Izabela” Exploitation Field is in the central part of the northern Adriatic. It consists of two gas exploitation platforms anchored directly onto the seabed. The seabed of the exploitation field is an alluvial plain where sandy, dusty and clay sediments were deposited during the Quaternary. The...

It consists of two gas exploitation platforms anchored directly onto the seabed. The seabed of the exploitation field is an alluvial plain where sandy, dusty and clay sediments were deposited during the Quaternary. The dominant reservoir rocks are Pliocene and Quaternary sands and loosely bound sandstones. Gas-bearing deposits are shallowly located (between 500–1000 m depth). One of the main challenges was the question of seabed subsidence due to gas exploration and its cross-boundary influence on the Italian coastline. The current research aims to present the response to this challenge at gas field Izabela, focusing on a subsidence model of the seabed as a consequence of the pressure drop in the reservoir due to exploitation.https://eurogeologists.eu/vasiljevic-geotechnical-challenges-at-adriatic-offshore-gas-platforms-subsidence-due-to-exploitation-at-the-izabela-exploitation-field/geotechnics
