... approximately 30 km southeast of the Havnsø structure. Natural gas has been injected and stored at Stenlille since 1989, where the reservoir occurs within a domal subsurface structure and is covered by a tight caprock. The Upper Triassic Gassum Formation consisting of interbedded sandstones and mudstones...

... helps reduce the cost and additional seismic surveys perhaps seen as a scientific luxury. For this reason, 3D Stenlille survey is representative of the kinds of data we may have available. Therefore, we develop an integrated workflow to characterize the Gassum Formation at the Stenlille aquifer...

... targeted for geothermal energy and storage of CO 2 . The Stenlille salt dome on Sjælland sandstones of the Gassum Formation, sealed by the overlying Fjerritslev Formation mudstones, has been used for decades as a seasonal storage for natural gas. With its comprehensive dataset of seismics, geophysical well...
