Clumped isotope analysis is a new analytical technique to characterise temperature historiesof oil and gas bearing carbonate rock formations. This information is crucial for oilexploration to determine where and at what depth oil reservoirs are most likely to bediscovered. Other techniques are used to obtain temperature histories but depend upon thepresence of fluid inclusions. However, inclusions are not always present and do not providethe same precision as clumped isotope analysis.Despite the clear benefits, globally only 12 laboratories use this technique. This is becauseclumped isotope analysis requires the use of customised high precision mass spectrometersand inlets. These systems cost in excess of £500K and can only analyse 2 to 3 samples perday. This technique will only become accessible to the oil and gas industry if costs can bereduced and the speed of analysis increased.Protium intends to develop a new sample preparation system that will allow isotope laserratiometry to be used instead of high precision mass spectrometers. The lower cost of laserratiometers could reduce overall equipment costs by up to two thirds.This system would also automate the analytical process thereby increasing sample throughout.The proposed system would process samples at a rate of 30 a day compared to 3 usingexisting techniques. If the project is successful, it will lead to the development of the firstautomated system for laser ratiometer clumped isotope analysis.Protium will achieve this by:1. Developing an efficient rock acid digestion system and water removal traps.2. Developing novel chemical traps to remove organic contaminants.3. Modifying existing bulk isotope laser ratiometery inlet and electronic flow controltechnology developed by Protium during a recently completed TSB funded developmentproject (Ref. 100984).

块状同位素分析是表征含油气碳酸盐岩地层温度史的一种新的分析技术。这些信息对于石油勘探决定在什么地方和什么深度最有可能发现油藏是至关重要的。其他技术用于获得温度历史，但依赖于流体包裹体的存在。然而，包裹体并不总是存在，也不能提供与团块同位素分析相同的精度。尽管有明显的好处，但全球只有12个实验室使用这种技术。这是因为集中同位素分析需要使用定制的高精度质谱仪和入口。这些系统的成本超过50万英镑，每天只能分析2到3个样本。只有在降低成本和提高分析速度的情况下，这项技术才能被石油和天然气行业所接受。Protium打算开发一种新的样品制备系统，该系统将允许使用同位素激光比谱法代替高精度质谱仪。激光辐射计的成本较低，可以减少总设备成本高达三分之二。该系统还将自动化分析过程，从而增加整个样品。与使用现有技术每天处理3个样品相比，该系统将以每天30个样品的速度处理。如果该项目成功，它将导致第一个自动化系统的发展，用于激光比率计团块同位素分析。Protium将通过以下方式达到这个目的：开发高效的岩石酸消化系统和除水陷阱。开发新型化学捕集器去除有机污染物。在最近完成的TSB资助的开发项目（参考文献100984）中，改进了Protium开发的现有体同位素激光比例计入口和电子流量控制技术。
