A growing Geophysical argument for the use of single-element pneumatic points sources has been developing over the last several years. They have been shown to significantly improve the low-frequency...
The text discusses the acquisition and imaging of 3D seismic data in the ultra-shallow waters of the Black Sea’s northwestern shelf, focusing on the Dolfin Inner shelf license areas. Despite depths...

We present a quantitative comparison of the sound emission for a range of compact marine source arrays geared towards different applications. Compact marine sources with adapted bandwidth provide...
We acquired data from a North Sea seabed seismic test measured by a 6-degree-of-freedom (6-DOF) sensor that provides three translational measurements (acceleration) along three axes and three...
Accurate pre-carbonate imaging is a critical necessity in the search for hydrocarbons yet presents substantial geophysical challenges. Preconceptions on what may or may not improve imaging in such...
Air guns are reliable sources widely used in the seismic industry. When failures occur, air bubbles are released in the water and can distort the emitted signals. To ensure optimal data quality,...
