In an effort to advance Continental Scientific Drilling in the USA, DOSECC is organising aseries of topical workshops. The workshop proposed here has two objectives, firstly to advancescientific studies of active high-enthalpy hydrothermal systems, and secondly to foster collaborationbetween academic scientists, government agencies, and industry. Such collaboration is highlydesirable because the scientific study of active hydrothermal systems requires drilling andsampling boreholes whose costs far exceed budgets normally available to academic scientists,whereas the geothermal industry commonly drills wells that access them.The Iceland Deep Drilling Project (IDDP) represents an excellent example of such a collaboration.From the outset academic scientists have been deeply involved in that project. The IDDP isinvestigating the economic feasibility of producing electricity from supercritical geothermalreservoirs. To test this concept an industry consortium planned to drilled a deep well inthe volcanic caldera of Krafla. However drilling had to be terminated at 2.1 km depth when900C rhyolite magma flowed into the well. Today the well is highly productive, estimated tobe capable of generating 35 MWe of dry superheated steam at a well-head temperature of ~440C.There is a significant undeveloped potential for developing high-enthalpy geothermal systemsin the western USA, Hawaii and Alaska. Although drilling into these deep unconventional geothermalreservoirs is more expensive, the higher productivity per well should offset this.It is proposed to compile and distribute a report that addresses industry's interest, abilities,research needs, and potential for collaborative projects that drill high-enthalpy systems.This will be based on the results of a broadly distributed questionnaire, and a three dayworkshop with participation by industry, government and university scientists. Hopefully thiswill help create a national program that enhances the scientific, technological and institutionalbasis for the development of new and more economic sources of alternative energy.

为了推进美国大陆科学钻探，DOSECC正在组织一系列专题研讨会。这里提出的研讨会有两个目标，首先是促进对活跃的高焓热液系统的科学研究，其次是促进学术科学家，政府机构和工业之间的合作。这种合作是非常可取的，因为对活跃的热液系统的科学研究需要钻探和取样钻孔，其成本远远超过学术科学家通常可以获得的预算，而地热工业通常钻探进入这些钻孔的威尔斯。冰岛深层钻探项目（IDDP）是这种合作的一个很好的例子。从一开始，学术科学家就深入参与了该项目。IDDP正在研究从超临界地热水库发电的经济可行性。为了测试这一概念，一个工业财团计划在Krafla火山口钻一口深井。然而，当900 ℃的流纹岩岩浆流入井中时，钻井不得不在2.1公里深处终止。今天，这口井是高产的，估计能够在井口温度约440 ℃下产生35 MWe的干燥过热蒸汽。在美国西部、夏威夷和阿拉斯加，开发高焓地热系统的潜力很大。尽管钻探这些深层非常规地热储层的成本更高，但每口井更高的生产率应该可以抵消这一点。建议编写并分发一份报告，说明行业的兴趣、能力、研究需求以及钻探高焓系统的合作项目的潜力。这将基于广泛分发的问卷调查结果，以及由行业参与的为期三天的研讨会，政府和大学科学家。希望这将有助于建立一个国家计划，加强科学，技术和制度基础的发展新的和更经济的替代能源。
