Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments
Advanced Science, EarlyView.This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

Wellbore Storage Effects in Geothermal Wells [PDF]
Society of Petroleum Engineers Journal, 1980 Abstract The early-time response in the well testing of a homogeneous reservoir customarily is expected to give a unit slope when the logarithm of pressure is plotted vs. the logarithm of time. It is shown that this response is a special case and that another non-dimensional parameter must be defined to describe the set of curves that ...

Chemical Logging of Geothermal Wells [PDF]
, 1980 Chemical logging was developed to permit identification of zones bearing geothermal water during drilling of geothermal wells. This technique consists of collection of circulation fluid samples at specified periods determined by drill-bit depth. These samples are analyzed for bicarbonate (HCO3−), Cl−, F−, Ca++, and silicon dioxide (SiO2).
