XRF signatures of hydrothermal dolomitization and alteration v2

ProGeo Consultants是一家为石油和天然气行业提供服务的咨询公司。其客户提出的最常见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昂贵的专门分析。由于岩心稀少且回收成本高，这是发现新储层的主要障碍。因此，一种更便宜和更快的替代方法来揭示热液蚀变的存在将是非常有帮助的。该项目的目标是测试是否可以使用微型XRF扫描仪对钻屑进行简单快速的分析，以识别和量化热液白云岩。事实上，钻屑比钻取岩心更便宜，而且数量级更频繁。该项目将分析大量已被明确解释为热液白云岩或热液蚀变岩的岩心样本，并将这些分析与同一岩层的钻屑分析进行比较。如果成功，该项目将使ProGeo Consultants能够增加其向该行业提供的服务组合。

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.
