Abstract

Seismic technologies have the potential to significantly enhance the exploration of subterranean layers in search of oil and gas reserves. In this context, this thesis discusses the practicality and advanced application of Seismic While Drilling technology, with a particular focus on stick-slip vibrations, which represent another kind of seismic source. The study commences with a fundamental exposition of methodologies such as vertical seismic profiling and borehole imaging, and it elucidates the intricacies inherent to these seismic imaging techniques. The study contributes to the ongoing discourse on the utilisation of stick-slip vibrations in SWD processes by synthesising theoretical insights with practical applications, with a particular focus on advanced techniques. Finally, it employs Python and MATLAB simulations to corroborate theories and demonstrate their possibility to be applied in complex geological settings, with a particular focus on the Algerian oilfields. This thesis demonstrates how SWD technology can revolutionise real-time subsurface imaging and drilling performance, thereby significantly advancing seismic exploration procedures.
