Low-Density High-Fluidity High-Strength Epoxy Resin Cement Slurry Technology for Wellbore Reconstruction

open access: yesZuanjingye yu wanjingye
The production rate of a shale gas well generally declines fast, resulting in a low average recovery of the well. Refracturing of an old well with shale gas production pressure depletion can effectively enhance the ultimate recovery of the well, and ...

Concatenated image completion via tensor augmentation and completion

open access: yes, 2016
This paper proposes a novel framework called concatenated image completion via tensor augmentation and completion (ICTAC), which recovers missing entries of color images with high accuracy.

Explanatory completeness

open access: yesActa Psychologica, 2020
All explanations are incomplete descriptions, but reasoners appear willing to assess some explanations as more complete than others. To explain this behavior, we propose a novel theory of the detection of explanatory incompleteness. The account is based on the assumption that reasoners represent explanations as mental models – discrete, iconic ...

Current Status and Trend of Geo-Steering Drilling Technology for Shale Gas Reservoir

open access: yesShiyou jixie
Shale gas resources are strategically vital for ensuring national energy security and achieving the “carbon peak and carbon neutrality” goals. However, shale gas reservoirs in China are generally characterized by low porosity, low permeability and strong

Elementary quotient completion [PDF]

open access: yes, 2012
We extend the notion of exact completion on a weakly lex category to elementary doctrines. We show how any such doctrine admits an elementary quotient completion, which freely adds effective quotients and extensional equality. We note that the elementary

Ultraviolet Completion of Flavour Models

open access: yes, 2010
Effective Flavour Models do not address questions related to the nature of the fundamental renormalisable theory at high energies. We study the ultraviolet completion of Flavour Models, which in general has the advantage of improving the predictivity of ...

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Hydraulic fracture optimization by using a modified Pseudo-3D model in multi-layered reservoirs

open access: yesJournal of Natural Gas Geoscience, 2018
The aim of hydraulic fracturing optimization is to maximize well productivity index by optimizing fracture geometry parameters. Height in geometry calculation is the most important parameter, especially in the multi-layered reservoirs due to the ...

A systematic review of the status of children's school access in low- and middle-income countries between 1998 and 2013: using the INDEPTH Network platform to fill the research gaps [PDF]

open access: yesGlobal Health Action, 2015
Background: The framework for expanding children's school access in low- and middle-income countries (LMICs) has been directed by universal education policies as part of Education for All since 1990. In measuring progress to universal education, a narrow
