Uncompromising Tools for Oil and Gas Exploration

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

• 了解盆或田间量表的相关关系

• identify elemental proxies used in paleoecological reconstructions

• aid in building sequence stratigraphic frameworks

• 识别岩石的物理特性进行钻孔和汇编

布鲁克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.

元素分析是该领域和石油地质学家的重要工具，可以表征和识别石油或气体的形成。可以通过X射线荧光（XRF）分析钻头，泥浆或核心。

• 台式S2 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 TIGERSeries 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.

X射线衍射（XRD）提供了有关沉积物或形成矿物质组成的其他信息。XRD通过其晶体结构区分具有相同或相似化学的矿物质。它不仅允许识别矿物DIFFRAC.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 PHASER. In a lab setting, theD8 ENDEAVORor theD8 ADVANCEis the optimal choice.

了解孔隙度和渗透率对于石油和天然气储层表征，沉积学，水文地质学和地下水研究很重要。XRM可以表征和可视化孔，孔径分布以及开放式孔隙网络的表征和可视化。该信息可能对石油和天然气生产模型，天然气或水洪水，模拟研究，污染流程建模，变形实验和沉积岩石学有深远的影响。

The analysis of shale reactivity typically involves a variety of analytical techniques, including but not limited to X-ray diffraction, X-ray fluorescence, gamma logging, optical microscopy, electron microscopy, total organic content, and cation exchange capacity. From a mineralogical perspective, XRD is widely considered to be the favored technique, particularly for discrimination between elementally similar phases.

For example, hematite (Fe2O3) and siderite (FeCO3) give similar elemental signatures but distinct diffraction patterns. Diffraction data are often obtained for both vertical and horizontal segments of wellbores. Analysis of the vertical section allows for the identification of zones with desirable physical properties. In horizontal segments of unconventional reservoirs, XRD is primarily used in geosteering, to ensure that the wellbore stays within a specific geological bed.
