<jats:p> Resolution enhancement is often applied to poststack seismic data to obtain higher frequency or wider frequency bandwidth. This enhancement could help seismic interpreters in resolving thinner layers that may not be visible on the original seismic data. The seismic inversion method is the other way to interpret seismic data. The inversion process produces an impedance volume as a layer property that can be used not only for interpretation but also for reservoir characterization. This research aims to study whether vertical resolution enhancement of seismic data preserves the amplitudes and how enhancement affects seismic inversion results. The experiments in this research are performed on synthetic and real data. The modeling is carried out by generating zero-offset synthetic traces using a convolutional model. Meanwhile, real data processing is carried out at the North Sea Volve Data Village at the Ty and Hugin formations. The resolution of the seismic trace is enhanced using a spectral division operator. The inversion techniques used in this research are model-based inversion and sparse spike inversion. The seismic trace after vertical resolution enhancement shows that the separation of events can be improved by this procedure. Inversion of the original and of the enhanced traces shows that the enhancement process still allows obtaining reliable inversion results both from model-based and sparse spike methods; however, there is no significant difference between the inverted impedance using the original trace and enhanced traces. This research concludes that the enhancement process keeps the seismic amplitude preserved for inversion, but it barely improves the inversion result. </jats:p>

<jats:p> The 3rd International Geomechanics Symposium (IGS2022) took place 7–10 November 2022 in Abu Dhabi. Focusing on the role of geomechanics in energy efficiency and sustainability, the technical program covered a range of technology applications including rock and in-situ stress characterization, natural fractures, faults, drilling, completion, stimulation, production, and reservoir engineering. It also showcased geomechanics applications in CO<jats:sub>2</jats:sub> sequestration, hydrogen storage, and new energies. </jats:p>

<jats:p> Modeling of the near surface plays a significant role in subsurface imaging, reservoir characterization, and monitoring. The Near-Surface Modeling and Imaging Workshop was created to address near-surface challenges in geoscience. The workshop has been held previously in 2014, 2016, and 2019. The latest instance of the workshop, 27–29 September 2022 in Muscat, Oman, continued the tradition. </jats:p>

<jats:p> In September, I will take office as SEG president. This year also happens to be my 50<jats:sup>th</jats:sup> as an SEG member, and that's a long time. In that time, the world has changed, our lives have changed, the Society's concerns have changed, and, consequently, SEG as a whole needs to change. </jats:p>
