摘要： A method for improving precision of measurement of material composition of formations determined by gamma ray spectral an analysis includes determining an accurate value of an amount of a selected by analyzing a spectrum of gamma rays detected from the formations using a technique that directly relates the gamma ray spectrum to the amount of the material. A precise value of the amount of the material is determined by analyzing the spectrum of detected gamma rays that indirectly relates the gamma ray spectrum to the amount of the material. A function relating the accurate value to the precise value over a selected axial interval along the wellbore is determined. The function is applied to the accurate value at at least one selected axial position along the wellbore to determine an accurate and precise value of the amount of the material.

摘要： The accurate determination of formation hydrocarbon or water saturation is a useful step in the petrophysical evaluation of petroleum reservoirs. This disclosure presents a new method for estimating hydrocarbon saturation directly from a porosity log and a total organic carbon (TOC) log. The method is enabled by the recent development of a geochemical spectroscopy logging tool that combines inelastic and capture gamma ray measurements to provide a robust and accurate TOC log. The method differs from the prior approach of using carbon-to-oxygen ratios that is most often applied in cased hole evaluation. The main advantages of this method are that it does not use knowledge of formation water resistivity, it does not rely on a resistivity model, it does not use an extensive calibration database, and it is largely independent of clay or other lithology effects. Here, the principles of the method and the main challenges are described, and calculations that explore uncertainties in the saturation estimates arising from uncertainties in the log inputs are presented. The statistical uncertainty in the estimate of hydrocarbon saturation is as good as 10 saturation units (s.u.) in conventional reservoirs with porosities of 15 porosity units (p.u.) or greater. The method has been applied to the determination of hydrocarbon saturation in a variety of formations, including bitumen-filled dolomite, heavy oil sand, and shaly-sands with both open hole and cased hole wells. The method works equally well in formations drilled and logged with either oil- and water-based mud. The saturation estimates have been benchmarked against a combination of conventional and new logging approaches (e.g., resistivity, magnetic resonance and dielectric logs) and core measurements, with generally excellent agreement among independent determinations. Hydrocarbon saturations can be determined accurately using the method in a number of formation types where conventional methods and models for estimating fluid saturation commonly fail, such as freshwater and unknown water salinity in formations under enhanced oil recovery. The case studies included herein demonstrate that a TOC log derived from geochemical spectroscopy logs can be used to obtain reliable estimates of hydrocarbon saturation in a wide range of environmental conditions and formations.
摘要翻译：准确测定地层碳氢化合物或水饱和度是石油储层岩石物理评价中的有用步骤。本公开提供了一种直接从孔隙度对数和总有机碳（TOC）对数估算烃饱和度的新方法。该方法通过最近开发的一种地球化学光谱测井工具实现，该工具结合了非弹性和捕获伽马射线测量，以提供稳健和准确的TOC日志。该方法与先前使用最常用于套管井评估中的碳 - 氧比的方法不同。该方法的主要优点是不使用地层水电阻率的知识，它不依赖于电阻率模型，它不使用广泛的校准数据库，并且在很大程度上独立于粘土或其他岩性效应。这里介绍了方法原理和主要挑战，并介绍了在日志输入中由不确定性引起的饱和度估计中不确定性的计算。烃类饱和度估计的统计学不确定度在孔隙率为15孔隙度单位（p.u。）以上的常规储层中为10个饱和单位（s.u.）。该方法已被应用于确定各种地层中的饱和烃饱和度，包括沥青填充的白云石，重油砂和具有开孔和套管井的石灰砂。该方法在用油和水基泥浆钻井和记录的地层中工作同样好。饱和度估计已经针对传统和新的测井方法（例如电阻率，磁共振和介电原子）和核心测量的组合进行了基准测试，在独立测定中具有一般的良好一致性。可以使用多种地层类型中的方法准确地确定烃饱和度，其中用于估计流体饱和度的常规方法和模型通常会失效，例如在强化采油下的地层中的淡水和未知的水盐度。本文包括的案例研究表明，来自地球化学光谱测井的TOC对数可用于在广泛的环境条件和地层中获得可靠的烃饱和度估计。

摘要： Composition-matched downhole tools and methods for using such tools are provided. One such method includes emitting neutrons using a neutron source in the downhole tool to generate formation gamma rays in a surrounding formation. At the same time, however, some of the neutrons may interact with different parts of the downhole tool to form tool gamma rays. The gamma ray spectra of at least some of the formation gamma rays and the tool gamma rays may be detected using a gamma ray detector. The tool gamma rays from the different parts of the tool may have a substantially similar spectral shape. As such, a processor may be used to analyze the spectra of the tool gamma rays using a single tool background standard, thereby simplifying the analysis and improving the precision of the results.

摘要： A method for correcting detected gamma ray spectra for the effects of energy analyzer pileup includes assigning detected gamma rays to channels in a multichannel analyzer (MCA). A pileup spectrum is estimated. The pileup spectrum is subtracted from the measured spectrum. The result thereof is compared to the preceding estimated pileup free spectrum and the estimating the pileup spectrum, subtracting the pileup spectrum and comparing is repeated until the difference between successive estimates of the pileup-free spectrum falls below a selected threshold.
