“…In addition, we suggest that the correspondence of the high‐amplitude anomalies and fractures likely mean that the interpreted “string of beads” are real geological features rather than geophysical artefacts. Carbonate platform margins are prone to syndepositional collapse, faulting and fracturing with reactivation during and post burial (Nolting & Fernández‐Ibáñez, 2021; Nolting et al, 2018). Consequently, fractures can act as long‐lived fluid conduits (Budd et al, 2013).…”

Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated through ocean drilling, but due to the low quality of vintage seismic data available, few spatial constraints exist on their stratigraphic evolution and large-scale diagenesis. Here, we present results from an integrated core-log-seismic study at Resolution Guyot and comparison with modern and ancient analogues. We EAGE EL-YAMANIetal.

“…(Agosta and Kirschner, 2003). These researches have demonstrated that factors such as lithofacies type, sedimentary environment, rock composition, and tectonic stress, have a signi cant impact on the formation and distribution of natural fractures in carbonate reservoirs (Neves et al, 2006;Liu et al, 2018;Regnet et al, 2019;Nolting et al, 2021). Due to the di culty of ultra-deep drilling and insu cient information.…”

The Shunbei ultra-deep carbonate strike-slip fault-controlled reservoir in Tarim Basin is rich in reserves. The strike-slip faults and natural structural fractures are the main storage space and ow channels of hydrocarbon resources. Therefore, studying the natural fracture development characteristics in this kind of reservoir is of great signi cance. The lithology of the Middle and Lower Ordovician strata in the Shunbei area is limestone and dolomite, including packstone, wackestone, grainstone, boundstone, lime mudstone, silici ed limestone and silty-ne crystalline dolomite, medium-coarse crystalline dolomite. Based on the statistics of fracture density and brittleness index of core samples, it is found that in limestone, lime mudstone has the highest brittleness index, while boundstone has the lowest; in dolomite, the brittleness index of mediumcoarse crystalline dolomite is higher than that of silty-ne crystalline dolomite. The natural structural fracture density has an obvious positive correlation with the rock brittleness index. The brittleness index of dolomite is generally higher than that of limestone. When the brittleness index is the same, dolomite has superior porosity and permeability whereas limestone has a stronger capacity to fracture. Those kinds of highly brittle layers in carbonate reservoirs are more likely to be geological sweet spots in the Shunbei area.
