Uncompromising Tools for Oil and Gas Exploration

Chemostratigraphy is the use of variations in the chemical composition of sedimentary successions to:

• understand correlative relationships at the basin or field scale

• identify elemental proxies used in paleoecological reconstructions

• aid in building sequence stratigraphic frameworks

• identify physical properties of rocks for drilling and compilations

Bruker provides tools for the elemental and chemical analysis of core and cuttings to make chemostratigraphy easy and scalable. Click below to learn more about applying chemostratigraphy to any sized project.

Elemental Analysis is an important tool for the field and petroleum geologist to characterize and identify petroleum- or gas-bearing formations. Drill cuttings, mud, or cores can be analyzed by X-ray Fluorescence (XRF).

• The benchtopS2 PUMASeries 2 reaches low detection limits on prepared drill cuttings in a mobile lab by using the Energy Dispersive XRF (EDXRF).

• The analysis of majors and traces in the lab is best performed by the floor standingS8老虎Series 2 Wavelength Dispersive XRF (WDXRF) spectrometer using either the GEO-QUANT package or custom calibrations.

• TheCTXis a compact portable countertop XRF ideal for rig operations, with a battery backup, push-button operation, spill-proof rugged aluminum case, and safety-interlocked lid. Now available with the MUDROCK matrix-matched calibration, the versatile GeoEXPLORATION calibration, or a custom calibration.

• TheTRACER 5gis the ideal portable XRF for core, outcrop, or cuttings. With a helium flush and graphene window it has the best light element performance in a handheld. When paired with the MUDROCK calibration or a custom matrix-matched formation-specific calibration it is the most trusted portable XRF in oil and gas.

Additional information on the mineralogical composition of the sediment or formation is offered by X-ray Diffraction (XRD). XRD distinguishes minerals that have the same or similar chemistry by their crystal structures. It not only allows the identification of minerals withDIFFRAC.EVA, but also offers standardless quantification using the Rietveld approach. Even non-crystalline phases may be quantified using this method. It enables pinpointing of potential reservoirs and host formations. A major advantage is the rather simple and quick sample preparation. The analysis of drill cuts can be done in a mobile lab using BRUKER’s benchtopD2移动器. In a lab setting, theD8努力or theD8 ADVANCEis the optimal choice.

Understanding porosity and permeability is important for oil and gas reservoir characterization, sedimentology, hydrogeology and groundwater studies. XRM enables characterization and visualization of pores, pore size distribution, and of open versus closed pore networks. This information can have profound implications on oil and gas production models, gas or water flooding, analog studies, contaminate flow modeling, deformation experiments and sedimentary petrology.

页岩反应性的分析通常涉及多种分析技术，包括但不限于X射线衍射，X射线荧光，伽马记录，光学显微镜，电子显微镜，总有机含量和阳离子交换能力。从矿物学的角度来看，XRD被广泛认为是最受欢迎的技术，特别是对于基本相似阶段的歧视。

例如，赤铁矿（Fe2O3）和辅助石（FECO3）给出了类似的元素签名，但具有明显的衍射模式。通常，对于井孔的垂直和水平段，经常获得衍射数据。垂直部分的分析允许鉴定具有理想物理特性的区域。在非常规储层的水平片段中，XRD主要用于地理座，以确保井眼留在特定的地质床中。
