Reliable, predictive models to optimize carbonate reservoir performance

A common weathering effect is the appearance of cracks due to material fractures. Previous exemplar-based aging and weathering methods have either reused images or sought to replicate observed patterns exactly. We introduce a new approach to exemplar-based modeling that creates weathered patterns on synthetic objects by matching the statistics of fracture patterns in a photograph. We present a ...

INTRODUCTION Human dental pulp stem/stromal cells (hDPSCs) in adults are primarily derived from the pulp tissues of permanent third molar teeth in existing literatures, whereas no reports exist, to our knowledge, on deriving hDPSCs from a tooth without the need for surgical procedure. The aim of this study was to raise a novel idea to source hDPSCs from complicated crown-fractured teeth requiri...

Abstract This study proposes the use of different machine learning techniques to predict estimated ultimate recovery (EUR) as a function hydraulic fracturing design. A set data includes 200 well production data, and completion designs were collected from oil wells in Niobrara shale formation. The design parameters include lateral length, number stages, total injected proppant slurry volumes, ma...

• Hydrate synthesis and decomposition occur simultaneously throughout phase transition process. growth habit is not monotonous change in fractured-porous medium sandstone at different stages of transition. occurences differs from that porous matrix system. The preferential occurence hydrates fracture leads to significantly permeability changes. Natural gas hydrate, as an efficient clean energy ...

This in vitro study examined the effect of surface defects on cutting blades on the extent of the cyclic fatigue fracture of HEROShaper Ni-Ti rotary files using fractographic analysis of the fractured surfaces. A total of 45 HEROShaper (MicroMega) Ni-Ti rotary files with a #30/.04 taper were divided into three groups of 15 each. Group 1 contained new HEROShapers without any surface defects. Gro...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

the bone is “fractured” or “broken”. While orthopaedic surgeons consider these terms synonymous, patients appear tocomprehend the terms as having different meanings. Given the commonality of this frequently posed question, it may beimportant for providers to assess patients’ level of understanding in order to provide optimal care. The purpose of thisstudy is to evaluate patients’ comprehension ...
