Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Heave effects on Drill String during connections [PDF]
, 2012 During the make-up and break-out of the connections, the drill string is wedged in the rotary table and the top of the drill string follows the platform heave movement as the bit is off bottom.

Minimizing Drill-String-Induced Wellbore Instability
, 2023 Objective/Scope: Every year the petroleum industry spends more than an estimated $6 billion in mitigating wellbore instabilities that account for nearly half of the drilling-related NPT (non-productive time).

Feminist Anthropology, EarlyView.Abstract This article advances three claims regarding the matrilineal organization of Wiradjuri society in central New South Wales. Drawing on the late nineteenth and early twentieth century ethnographic record, it demonstrates that Wiradjuri descent, totem, moiety identity, and ceremonial authority were and are matrilineally organized, despite ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

iMeta, EarlyView.Transient exposure to ampicillin results in restructuring of microbiota to favor oxygen‐tolerant bacteria, whereas osmotic laxative perturbation preserves Bacteriodota. Ampicillin‐ but not laxative‐exposed environment favors establishment of rmpA phase variants that lost hypermucoviscosity but short‐chain fatty acids present in the laxative‐exposed gut

PASSIVE VIBRATION CONTROL OF PERIODIC DRILL STRING [PDF]
, 2017 In this dissertation, the stop and pass bands (i.e. the band gaps) characteristics are determined for gyroscopic systems by developing an approach which is compatible with such class of systems which is based on the concept of Bloch wave propagation in ...
