World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
Deep Underground Science and Engineering, EarlyView.The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

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.

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).

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Valence Asymmetries of Traits in Dating Contexts
European Journal of Social Psychology, EarlyView.ABSTRACT Research on traits in dating contexts has typically focused on trait content. We instead examined structural differences in trait frequency and similarity. Prior work suggests that positive information is more frequent, whereas negative information is more diverse and less similar.

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 ...
