Natural gas production from hydropressured aquifers [PDF]
, 1981 Discussed in this paper are the global occurrences of natural gas in hydropressured aquifers. The nature of the producing mechanism is such that under most circumstances gas production is relatively small compared to conventional gas sources.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects
Advanced Engineering Materials, EarlyView.This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

What drove down natural gas production in Argentina? [PDF]
We address the causes behind the drop in natural gas production in Argentina since 2004, starting from a basic supply model that depends on economic incentives, and adding control variables related to different potential explanations such as firm ...

Natural gas conversion V : proceedings of the Fifth International Natural Gas Conversion Symposium, Giardini Naxos-Taormina, Italy, September 20-25, 1998 / [PDF]
, 1998 On January 1988, the ascertained and economically accessible reserves of Natural Gas (NG) amounted to over 144,000 billion cubic meters worldwide, corresponding to 124 billion tons of oil equivalents (comparable with the liquid oil reserves, which are ...

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Government involvement in liberalised gas markets; a welfare-economic analysis of Dutch gas-depletion policy [PDF]
This report analyses the welfare effects of two major components of the Dutch gas-depletion policy: the offtake guarantee for small-fields gas and the cap on production from the Groningen field.
