“…In the special case of the Snøhvit Field, uplift and erosion has been invoked as the major factor for fluid leakage at the detriment of tectonics and other mechanisms (Cavanagh et al, 2006;Chand et al, 2014Chand et al, , 2008Laberg et al, 1998;Ostanin et al, 2012b Gabrielsen et al,1990;Nickel et al, 2012).

“…Deep-sourced hydrocarbon plumbing systems are often sourced from thermogenic gas migration and shallow sourced gas migration can be from organic gas (Andresen and Huuse, 2011;Andresen, 2012;Ostanin et al, 2012b). The main trigger and driving mechanisms are:…”

“…In evidence that fluid-flow was active during the early stages of glaciation and is an ongoing process in the study area (Løseth et al, 2009). Hence, a phase of fluid migration may have taken place shortly after the last glacial maximum as documented by the large number of buried pockmarks on the URU (see the works of Ostanin et al, 2012aOstanin et al, , 2012bOstanin et al, , 2013.…”

High-quality 3D seismic data are used to analyze the history of fault growth and hydrocarbon leakage in the Snøhvit Field, southwestern Barents Sea. The aim of this work is to evaluate the role of tectonic fracturing as a mechanism driving fluid-flow in the study area. To achieve this aim, an integrated approach including seismic interpretation, multiple seismic attribute analysis, fault modeling and displacement analysis was used.The six major faults in the study area are dip-slip normal faults which are characterized by complex lateral and vertical segmentation. The three main episodes of fault reactivation interpreted were in late Jurassic (Kimmeridgian), early Cretaceous and Paleocene times. Fault reactivation in the study area is mainly through dip-linkage. Throw-distance plots of the representative faults also revealed along-strike linkage and multi-skewed C-type profiles. The throw profiles show that faults in the study area evolved through polycyclic activity involving both blind propagation, syn-sedimentary activity and that they have their maximum displacement at the reservoir zone. The expansion and growth indices provide evidence for coeval fault activity with sedimentation and interaction of the faults with a free surface during their evolution.

“…Uplift and erosion in the Hammerfest Basin can have affected the integrity of the seals causing leakage of hydrocarbons [2][3][4]. This has increased the exploration risks leading to the high number of dry wells.…”

“…The driving factors for the petroleum system of the Hammerfest Basin were uplift and erosion from the Paleocene til the Pleistocene which caused the depletion of hydrocarbon accumulations [5]. However, current investigations indicate that leakage is also a major exploration challenge in the basin [2,[6][7][8]. Especially, petroleum system modelling and interpretation of the deeper horizons, including delineating the basement, have been another challenge.…”

Further migration of oil out of the reservoir and leakage to the seabed follows the AFC, TFFC along the boundary faults of the graben structure.Figure 12: Gas upward migration from the source rocks into the reservoirs and the lateral migration within the source rocks. Further upward migration out of the reservoirs and leakage to the seabed throughout the basin is observed.
