Seafloor deformation monitoring is a new technology concept for offshore oil and gas reservoir monitoring. It has the potential to cheaply and continuously monitor long term production induced changes in the reservoir and overburden and the data can also be used to spot any instantaneous events such as overburden instability or fault slip. At Ormen Lange, Norway´s second largest gas field, a small trial network was deployed on the seafloor in 2007, followed by a full-field network in 2010. The network was operational for 5½ years before being retrieved in 2016.
