Most rock masses contain natural fractures. In many engineering applications, a detailed understanding of the characteristics fluid flow through fractured mass is critically important for design, performance analysis, and uncertainty/risk assessment. this context, fractures fracture networks play decisive role in conducting as permeability general orders magnitudes greater than that intact matr...

Most current seismic methods to seismically characterize fractures in tight reservoirs depend on a few anisotropic wave propagation signatures that can arise from aligned fractures. While seismic anisotropy can be a powerful fracture diagnostic, a number of situations can lessen its usefulness or introduce interpretation ambiguities. Fortunately, laboratory and theoretical work in rock physics ...

methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

Abstract Carbonate reservoirs in Iran are the most important and main sources of oil gas production. Hydrocarbon flow rates from carbonate heavily rely on development natural fractures. This study focuses role fractures reservoir quality considering Sarvak (southwest Iran) as second Iran. To identify small-scale around borehole walls, cores description image logs were utilized. Due to high cost...

conclusions although external fixation in open pediatric fractures and severe injuries is recommended, intramedullary nailing is also an effective method with low complications. combining pins and flexible intramedullary nails is effective in developing more stability and is not associated with more complications. background tibial fractures are the third most common pediatric long-bone fractur...

evidence acquisition a search of pubmed for studies on proximal fifth metatarsal fracture and jones fracture focusing on the classification and management was performed. the reference list of the retrieved articles was searched for additional related studies. conclusions lawrence and botte’s classification of proximal fifth metatarsal fractures is recommended by experts, due to its implication ...

Steering acid fracturing is a technique that improves the conductivity of carbonate reservoir. It widely used in However, due to lack comparative experiments, application steering improve results still unknown. Therefore, series true triaxial experiments were conducted study The specimens experiment from Qixia group and Dengsi Member Sichuan, China. In this study, slick water, cross-linked gel,...

Abstract In this paper, the development of a three-dimensional, two-phase fluid flow model (Modified Embedded Discrete Fracture Model) to study performances fractured horizontal well in deep-marine shale gas is presented. Deep-marine resources account for nearly 80% China, which decisive resource basis large-scale production. The dynamic characteristics deep reservoirs are quite different and m...

background: arterial damage is sometimes associated with supracondylar fractures of the humerus. diagnosis and careful management of the fracture and arterial repair is crucial. objectives: the aim of this study was to determine the prevalence and outcome of supracondylar fractures of the humerus with signs and symptoms of limb ischemia, before and after arterial decompression or arterial recon...
