Natural history of medial clavicle fractures

Injury, 2016
Fractures of the medial third of the clavicle comprise less than 3% of all clavicle fractures. The natural history and optimal management of these rare injuries are unknown. The aim of our study is to describe the demographics, management and outcomes of patients with medial clavicle fractures treated at a Level 1 Trauma Centre.A retrospective review ...

On the nature of stress fractures

The American Journal of Sports Medicine, 1978
It is felt that stress fractures are caused by excessive, repetitive muscle forces acting across the affected bone. These fractures should be suspected in participants of athletic endeavors who present with a history of persistent, focal, activity-related pain regardless of their stage of physical conditioning.

Flow diagnostics for naturally fractured reservoirs

Petroleum Geoscience, 2018
Reliable production forecasting for fractured carbonate reservoirs is a challenge. Natural fractures, adverse wettability and complex matrix heterogeneity are all uncertain and can all negatively impact upon recovery. Ideally, we should consider different reservoir concepts encapsulated in a large ensemble of reservoir models to quantify the impact of ...

Mechanism for Network Fracturing in Natural Fractured Reservoir

Advanced Materials Research, 2013
By the methods of in-house experiment and theory analysis, the fracture initiation, stretch and interconnected mechanism of natural fracture is studied in the fracturing process of main fracture and branch fracture extending. The results have shown that, the hydraulic fracture in fractured formation is composed of a few main fractures in large size and

Multilevel Fracture Network Modeling of Naturally Fractured Reservoirs

SPE Reservoir Simulation Symposium, 2005
Abstract This paper provides a review of common approaches for simulation of naturally fractured reservoirs and a new model formulation that is more amenable to the utilization of detailed geologic information from deterministic models, multipoint statistical simulations (MPS), and discrete fracture network (DFN) models.

The Nature of Fracture

2016
Our objective in this introductory chapter will be to describe the general features of the fracture process and to introduce some of the terminology that will be used. After doing this, we will attempt to trace the route by which our present understanding of fracture developed.

Hydraulic Fracturing Technology Design in Natural Fracture Reservoirs

Advanced Materials Research, 2014
Nowadays, hydraulic fracturing has become the mainly treatment in low permeability reservoirs, but the hydraulic fracturing design technology in different reservoirs still use common methods. Natural fracture reservoirs mainly include granite reservoir, basalt reservoir and igneous rock reservoir which its hydrocarbon pore volume is fracture system. As

Predicting Fractured Well Performance in Naturally Fractured Reservoirs

International Petroleum Technology Conference, 2013
Abstract Multiple hydraulic fracture treatments in the reservoirs with natural fractures create complex fracture networks. Predicting well performance in such a complex fracture network system is an extreme challenge. The statistical nature of natural fracture networks changes the flow characteristics from that of a

Effect of Natural Fractures on Hydraulic Fracture Propagation

SPE European Formation Damage Conference, 2005
Abstract Various fracture interaction criteria were reviewed and a systematic study is presented to analyze the effect of natural fractures on hydraulic fracture propagation. From the literature review, the approach of Warpinski and Teufel was adopted to evaluat the fracture propagation that would occur after a hydraulic fracture ...

Hydraulic Fracture Propagation in Pre-Fractured Natural Rocks

SPE Hydraulic Fracturing Technology Conference, 2011
Abstract We conducted a series of hydraulic fracture initiation tests with fractured natural rock samples. The objective is to characterize the interaction between hydraulic fracture initiation and natural fracture infiltration and opening.
