Dasht-e-Arjan is a northeast trending graben located 65 km west of Shiraz. It was formed along active segments of the Korrehbas fault, perpendicularly to the Shahnesh in and Salamati anticlines. Oriented sampling from bordering fault planes and striations was carried out to evaluate the relative amounts of paleostress/strain needed to form the graben. Measurements of e-twins and c-axis of calci...

Assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. Today, the application of reservoir software and Image logsplay a central role in resolving this problem. Electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. This enables the geoscientists t...

[1] We investigate the development of fracture distributions as a function of displacement to determine whether damage around small and large faults is governed by the same process. Based on our own field work combined with data from the literature, we find that (1) isolated single faults with small displacements have macrofracture densities that decay as r, where r is distance from the fault p...

Fractures of multi-scales and multi-origins are primary storage space effective seepage channels for metamorphic buried-hill reservoirs. They not only allow communication between various pores to enhance capacity, but also essential high yields. Fracture development controlling factors at reservoirs Bozhong 19-6 Gas Field were investigated based on imaging log, core data, experiments, e.g., thi...

The basement of southeast Brazil is traditionally interpreted as the result Neoproterozoic and early Paleozoic orogenic cycles. Wide regions Atlantic Plateau (southeast Brazil) are characterized by rocks tectonic structures Precambrian age. According to classical literature, these have not been affected tectonics since Miocene, despite fact that they rest close Cenozoic basins, which suffered r...
