Analysis Of The Influencing On The Extension Limit Of A Horizontal Wells With Ultra-Long Horizontal Sections

open access: yesJournal of Applied Science and Engineering, 2023
Compared to conventional vertical wells, horizontal wells with Ultra-Long horizontal sections greatly increase the oil drainage area and can significantly increase oil and gas production from individual wells.

Interference fracturing: Nonuniform distributions of perforation clusters that promote simultaneous growth of multiple hydraulic fractures [PDF]

open access: yes, 2015
One of the important hurdles in horizontal-well stimulation is the generation of hydraulic fractures (HFs) from all perforation clusters within a given stage, despite the challenges posed by stress shadowing and reservoir variability.

Key surface logging technologies in horizontal well geosteering

open access: yesPetroleum Exploration and Development, 2012
In the drilling of horizontal wells, the core task of surface logging is to guide geosteering while drilling by using collected data including electrical property, lithology, petrophysics, and oil/gas-bearing properties. Surface logging in the horizontal

Horizontal Stratification during Deep Convection in the Labrador Sea [PDF]

open access: yes, 2014
Deep convection—the process by which surface waters are mixed down to 1000 m or deeper—forms the primary downwelling of the meridional overturning circulation in the Northern Hemisphere.

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
