ProGeo Consultants is a consulting company providing services for the oil and gas industry. One of the most common questions formulated by its clients has been how to recognize hydrothermal dolomite and associated processes. The conventional way of asserting the existence of hydrothermal alteration is via core studies, and via time-consuming costly specialized analyses based on microscopy or geochemistry. Because cores are rare and expensive to retrieve, it is a major obstacle for the discovery of new reservoirs. Thus, a cheaper and quicker alternative way to reveal the existence of hydrothermal alteration would be very helpful. The goal of this project is to test whether the simple and fast analysis of drill cuttings using micro-XRF scanners can be used to recognize and quantify hydrothermal dolomite. Indeed, drill cuttings are cheaper and orders of magnitude more frequent than drilled cores. The project will analyse a large number of core samples that have been clearly interpreted as hydrothermal dolomite or hydrothermally altered, and these analyses will be compared to the one of drill cuttings from the same rock formations. If successful, the project will allow ProGeo Consultants to increase its portfolio of services to be offered to the industry.

ProGeo Consultants 是一家为石油和天然气行业提供服务的咨询公司。客户最常见的问题之一是如何识别热液白云石和相关过程。断言热液蚀变存在的传统方法是通过岩心研究，以及基于显微镜或地球化学的耗时且昂贵的专业分析。由于岩心稀有且回收成本昂贵，因此成为发现新储层的主要障碍。因此，一种更便宜、更快捷的替代方法来揭示热液蚀变的存在将非常有帮助。该项目的目标是测试使用微型 XRF 扫描仪对钻屑进行简单快速的分析是否可用于识别和量化热液白云石。事实上，钻屑比钻取岩心更便宜，而且频率更高。该项目将分析大量已被明确解释为热液白云石或热液蚀变的岩心样本，并将这些分析与来自相同岩层的钻屑进行比较。如果成功，该项目将使 ProGeo Consultants 能够增加向行业提供的服务组合。
