The Aiza research area covers over 650 km2 of the northern Adriatic offshore, a common Adriatic foreland of the older Dinarides on the NE, and the younger Apennines on the SW. High-quality 3D reflection seismic data were used to investigate the area’s Mesozoic to Cenozoic tectono-stratigraphic evolution. Four main seismo-stratigraphical horizons were recognized: Base of Carbonate Platform (BCP), Top of Carbonate Platform (TCP), Messinian Erosional Surface (MES), and a Plio-Quaternary horizon (PlQh), as well as the dominant faults. The results depict the geological setting and tectonic evolution of the area. A long-lasting (Jurassic to Cretaceous) stable NW-SE striking platform margin evolved probably along the inherited Triassic normal fault. The marginal belt of the platform was affected during the Late Cretaceous to Palaeogene by extension and opening of the intra-platform basin, probably on the southern limb of the then developing Dinaric forebulge. The transverse fault system (Kvarner fault) was probably reactivated as a strike-slip zone during the late Miocene tectonic reorganization. The area was tilted to the SW during the Pliocene, in the distal foreland of the progressively northward propagating Northern Apennines. Sub-horizontal late Quaternary cover of Dinaric and Apenninic structures could imply active subsidence of the foreland in between nowadays sub-vertically exhuming neighboring orogenic belts.

“…At the same time during recent years new approaches to the use of the sequence-stratigraphy method have been proposed by many researchers (Abd Al-Salam Al-Masgari et al, 2021;Ainsworth, 2010;Miller et al, 2018;Nwaezeapu et al, 2018;Okpikoro and Olorunniwo, 2010;Zhu et al, 2013).

It is known that over 90% of oil, gas and gas condensate in Azerbaijan is produced from Productive Series (PS) of the Early Pliocene. In this respect, the detailed study of Pro- ductive Series deposits and their evolution conditions has a special value. Currently in most sedimentary basins of the world the latest highly informative methods of stratigraphic analysis are applied and one of these methods is sequence-stratigraphy, which is used in this study. The application of the concept of sequence stratigraphy enables an in-depth analysis of the study area to be conducted from a geological point of view. Despite the fact that the search for oil and gas deposits in the basins of Azerbaijan Republic has been going on for many years, there is a limited understanding of the distribution of elements associated with the oil system within the sequence stratigraphic structure. This is evidenced by the small number of scientific publications that exist in this area at the moment. To study in more detail the sedimentation process of PS of the Pliocene in the Galmaz field the genetically tied facies have been outlined and correlated within the framework of chronostratigraphic boundaries. As the study targets we have chosen the stages of Absheron, Akchagyl and PS of Pliocene in the Galmaz field. New data acquired by well logging techniques were re-examined in detail. To analyze and interpret the data , NeuralogTM and PetrelTM software were applied. From positions of the sequence-stratigraphy and taking into account the curve features (gamma ray log) predictions of the sedimentation environment of PS have been made. In the study process the sequences and system tracts have been outlined and studied, the sedimentation periods of the outlined sequences have been defined. It has been suggested to apply stratigraphic surfaces for tracing changes in regression and transgression surfaces. Clay and sand fractions of rocks were evaluated with further lithological analysis. On the gamma-ray curves, the intervals with intensity values less than 3.5 mR/h were considered as reservoir layers. At the same time, the normalized value of αSP, calculated from the curve of Spontaneous Polarization, was assumed to be greater than 0.6. Based on the sequence-stratigraphy analysis of oil-field geophysical data it has been established that the geological section of the Galmaz area was developing at various rates and in frequently changing energy mode. It has been also made clear that parasequences of the Absheron stage and Productive Series were formed in progradation mode by detritus brought by river flows. Akchagyl sediments play the role of the regional major cap in the basin.

“…Advancements in modern seismic interpretation technologies offer several seismic attributes to compute structural attribute volumes and to enhance faults in seismic data for automatic fault extraction. Some attributes compute the continuity of seismic reflections, such as semblance [2], or coherency [5,[31][32][33][34], while others measure the discontinuity, such as variance [4,35], or gradient magnitude [36], etc. These attributes are dependent either on amplitude contrast or reflector's continuity and highlight faults only when the set criteria are fulfilled.…”

Automated Fault Detection and Extraction under Gas Chimneys Using Hybrid Discontinuity Attributes

3D-seismic data have increasingly shifted seismic interpretation work from a horizons-based to a volume-based focus over the past decade. The size of the identification and mapping work has therefore become difficult and requires faster and better tools. Faults, for instance, are one of the most significant features of subsurface geology interpreted from seismic data. Detailed fault interpretation is very important in reservoir characterization and modeling. The conventional manual fault picking is a time-consuming and inefficient process. It becomes more challenging and error-prone when dealing with poor quality seismic data under gas chimneys. Several seismic attributes are available for faults and discontinuity detection and are applied with varying degrees of success. We present a hybrid workflow that combines a semblance-based fault likelihood attribute with a conventional ant-tracking attribute. This innovative workflow generates optimized discontinuity volumes for fault detection and automatic extraction. The data optimization and conditioning processes are applied to suppress random and coherent noise first, and then a combination of seismic attributes is generated and co-rendered to enhance the discontinuities. The result is the volume with razor sharp discontinuities which are tracked and extracted automatically. Contrary to several available fault tracking techniques that use local seismic continuity like coherency attributes, our hybrid method is based on directed semblance, which incorporates aspects of Dave Hale’s superior fault-oriented semblance algorithm. The methodology is applied on a complex faulted reservoir interval under gas chimneys in a Malaysian basin, yet the results were promising. Despite the poor data quality, the methodology led to detailed discontinuity information with several major and minor faults extracted automatically. This hybrid approach not only improved the fault tracking accuracy but also significantly reduced the fault interpretation time and associated uncertainty. It is equally helpful in detecting any seismic objects like fracture, chimneys, and stratigraphic features.
