The lateral sealing ability of a normal fault is a major factor in creating hydrocarbon traps. Therefore, a methodology for assessing the sealing ability of faults in the siliciclastic sequences of subsidence basins has been established; moreover, by using this methodology, the uncertainty inherent in hydrocarbon exploration can be decreased. Moreover, the petrophysical properties of fault roc...

Bozhong A Oilfield is located in the northeast of Huanghekou Sag Bohai Bay Basin, and a complex fault block oilfield. The main oil bearing horizon lower Minghuazhen Member, belonging to shallow water delta sedimentation. For rolling exploration evaluation adjacent blocks, this paper uses mudstone smear method analyze accurately characterize lithological contact relationship between two walls fa...

Fault sealing is one of the key factors controlling hydrocarbon accumulations and trap volumetrics and can be a significant influence on reservoir performance during production. Fault seal is, therefore, a major exploration and production uncertainty. We introduce a systematic framework in which the geologic risk of faults trapping hydrocarbons may be assessed. A fault may seal if deformation p...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

That faults are of fundamental importance in petroleum systems cannot be stressed enough. The role the faults play, however, is complicated by their dual nature as fluid seals and conduits. Understanding a fault’s behavior demands extensive knowledge of its past geologic history, core samples, pressure measurements, and well logs. Further complicating matters, the sealing capacity of a fault us...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...

The structure of caprocks is often greatly altered by different scales faults or fissures in long-term geological tectonic evolution, and the sealing performance may be deteriorated. In this paper, a simplified model characterized as multilayered sandstone fault-bearing extracted from Shuang 6 underground gas storage located Liaohe oilfield was established. Different fault geometry (e.g., lengt...
