The source of lower crustal earthquakes has been attributed to the transport of magma through the crust, although, other mechanisms such as thermal cooling and secondary boiling of stagnant magma bodies in the crust could equally well be used to explain the seismicity. Deep earthquakes have also ...
Cr Hawkins said he saw ”little value” in the briefing, as there was ”nothing they could say to convince me that the environmental and economic aspirations of our community are well served by more deep-sea drilling”. Cr Damien Newell, said ”if I go, it will be in protest. The scie...

@Michigan Value Investor Well, where do you think Buffett got that lions share of cash to purchase national indemnity, which later sprawled into a $100 billion insurance franchise? It's the textile mills getting a terrific two years of return before it ultimately fades into oblivion. So, at...
and the deep holes were first constructed and blasted, and the shallow holes were built later, and the deep holes were detonated at once, and the length of the shallow holes was not more than 6 m, and finally the drilling hole was cut off, and the overburden layer of the goaf was ...
Since hydrogen storage in saline aquifers typically requires the drilling of new wells, an understanding of the potential impact of different well set-ups on the performance of storage operations is essential. Most previous numerical studies were performed using either a single or a predefined multi-...
[1,2,3]. A defined residual stress condition in the near-surface area can be accomplished by post-treatments. A well-suited and often used process is the mechanical treatment deep rolling. The process is very popular due to its easy integration into the manufacturing process, its cost-...
Investigation drilling, as a mandatory part of research work, must be of high quality, implying that the core has to be continuous, practically over its full length, with preserved natural structure, and with the possibility of an unlimited choice of representative samples for laboratory and other...
