“…Those data are generally not available in the oil and gas companies. The slip tendency-based stress inversion approach was previously demonstrated mainly by outcrop data [34] but it hasn't been used with the seismic reflection data. Previously 3D seismic reflection data was used by [55] to perform the slip tendency based stress inversion through the slip tendency algorithm presented by [54] to identify the stress field of the Xicaogu area in the Bohai Bay Basin.…”

“…Paleostress field investigation is useful to explain fault reactivation [22] [23], and the timing and designs of fault leakage [22] [23] [24] [25]. Nowadays, a couple of methods have been proposed for estimating Paleostress analysis, such as earthquake focal mechanisms [26], fault-slip data inversion [27]- [34]. However, these techniques are based on the outcrops and oriented core data.…”

Paleostress plays a significant role in controlling the formation, accumulation, and distribution of reservoirs, and this could be an important factor in controlling the production of hydrocarbons from the unconventional reservoirs. In this study, we will use 3D seismic reflection data to perform the slip-tendency-based stress inversion to determine the stress field in the basement of the northern slope area in the Bongor Basin. The dataset for this technique is easily available in the oil and gas companies. The stress inversion results from the basement of the northern slope area of Bongor basin show that the maximum principal stress axis (σ1) is oriented vertically, the intermediate principal stress axis (σ2) is oriented N18˚ and the minimum principal stress axis (σ3) is oriented N105˚, and σ2/σ1 = 0.60 and σ3/σ1 = 0.29. The findings of this paper provide significant information to understand the fault reactivation at the critical stage of hydrocarbon accumulation and the regional tectonic evolution.

“…The area is marked by late-stage strike-slip and normal faults in NE-SW and ESE-WNW directions. A paleostress analysis of those faults indicates that NW-SE-directed extensional tectonics affected the region during brittle deformation (Tiwari et al, 2020b). During brittle deformation, previous shear zones have been reactivated as normal faults, for example, the Kui-Chitraseni and Surpagla-Kengora faults.…”

“…The Sandmata granulite was exhumed at ca 1.7 Ga (Table 2). After the exhumation of the rocks to the brittle-ductile transition zone, the rheological contrast between the middle and upper crust led to lateral extrusion of material exemplifying escape tectonics (Tiwari et al, 2020b). Subsequently, extensional faulting and erosion exposed them to the surface.…”

“…Paleostress analysis offers much information about the structural history of a particular region and can shed a light on the deformation processes within different lithologies. It aims to establish the magnitude and orientation of the stress field in which a population of faults and fractures are created (e.g., Rowland et al, 2007;Zain Eldeen et al, 2002;Radaideh and Melichar, 2015;Soumaya et al, 2018;Al-Shwaily and Al-Obaidi 2019;Tiwari et al, 2020). Several hypotheses have been presented to explain the structural styles of the Dead Sea Transform's eastern side (DST).…”

This research derives paleostress tensors for deformation affecting late Cretaceous rocks between Amman and Al-Hallabat, northern Jordan and reconstructs the region's tectonic history. Three distinct formations are exposed in the investigated area: Wadi As Sir (Turonian), Wadi Umm Ghudran (Santonin), and Amman silicified limestone (Campanian). The stress inversion is derived from data collected on the fault-slip at four different locations, revealing both extensional and compressive regimes. The research region is divided into two sectors based on these paleostress regimes: a SW sector dominated by extensional to transtensive stress regimes (with a stress index varying from 0.68 to 0.80) and a NE sector characterized by compression (with a stress index ranging from 2.60 to 2.65). Furthermore, the SE stress sector is found to be consistent with the NNW-SSE Neogene extension. In contrast, the NE stress sector was associated with a Syrian Arc Stress Field orientated E-W to ESE-WNW throughout the late Cretaceous. Fracture analysis identifies two types of fractures within the study area: shear and extensional. Both fractures correspond with fault-slip data and inferred stress direction.
