Abstract An interlaboratory study (ILS) was conducted to test reproducibility of vitrinite and solid bitumen reflectance measurements in six mudrock samples from United States unconventional source-rock reservoir petroleum systems. Samples selected from the Marcellus, Haynesville, Eagle Ford, Barnett, Bakken and Woodford are representative of resource plays currently under exploitation in North America. All samples are from marine depositional environments, are thermally mature (Tmax >445 °C) and have moderate to high organic matter content (2.9–11.6 wt% TOC). Their organic matter is dominated by solid bitumen, which contains intraparticle nano-porosity. Visual evaluation of organic nano-porosity (pore sizes 1.0 produced lowest R values, generally ≤0.5% (absolute reflectance), similar to a prior ILS for similar samples. Other traditional approaches to outlier removal (outside mean ± 1.5*interquartile range and outside F10 to F90 percentile range) also produced similar R values. Standard deviation values

在北美非常规烃源岩储层石油系统中测试镜质体和固体沥青反射率测量的重现性

摘要 进行了一项实验室间研究 (ILS),以测试来自美国非常规烃源岩储层石油系统的六个泥岩样品中镜质体和固体沥青反射率测量值的再现性。从 Marcellus、Haynesville、Eagle Ford、Barnett、Bakken 和 Woodford 中选择的样本代表了北美目前正在开发的资源区。所有样品均来自海洋沉积环境,热成熟(Tmax > 445 °C)并且具有中到高的有机质含量(2.9-11.6 wt% TOC)。它们的有机质以固体沥青为主,其中含有颗粒内纳米孔隙。有机纳米孔隙率的视觉评估(孔径 1.0 产生最低的 R 值,通常≤0.5%(绝对反射率),类似于类似样品的先前 ILS。其他传统的异常值去除方法(超出平均值 ± 1.5*四分位范围和 F10 到 F90 百分位范围之外)也产生了类似的 R 值。标准偏差值
