Development of Drilling Technology for Deep-seated Geothermal Resources

Concept of the deep-seated geothermal resources Deep-seated geothermal resources is defined as the depth of 3000-4000m at temperature of approximately 350 degrees C. And it is considered that those deep-seated geothermal resources exist below shallow geothermal reservoirs whch already exploited. 580,000 KW. And it is indispensable to explore geothermal resources " to increase it rapidly. In Jap...

Drilling Facility Design – “ A Wells Up Approach ”

There are a number of developments where new dry tree platform drilling rigs are specified. In some cases the geographical location, number of wells to be drilled and the ongoing life of field intervention requirements lead to the need for a permanent rig installation. The majority of permanent offshore rig installations has in the main been confined to the N. Sea region. As a result there is a...

SCIENTIFIC COMMENTARIES Steering technology for deep brain stimulation

Over the last two decades, deep brain stimulation has become widely accepted as a treatment for Parkinson’s disease, dystonia and tremor, and its use is increasing in disorders such as obsessivecompulsive disorder, depression and pain. The primary objective is always to achieve symptom suppression with few or no side effects; in other words, to attain as wide a therapeutic window as possible. I...
