In "Crude Oil Analysis," we examine the physical properties (density, kinematic viscosity, pour point, and cloud point) and chemical properties (sulfur content, residual carbon content, wax content, component composition, etc.) of crude oil and gas condensate produced from geological layers thousands of meters underground. Additionally, the analysis data is utilized for identifying production layers, estimating the depositional environment and organic origin of source rocks, examining crude oil processing methods for quality control, conducting quality checks based on sales contracts, and analyzing reservoir fluid models. [Measurement, Testing, and Analysis] ■ Density Measurement ■ Kinematic Viscosity Measurement ■ Pour Point and Cloud Point Measurement ■ Sulfur Content Measurement ■ Distillation Test ■ Component Composition Analysis *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or feel free to contact us.
Source rock refers to the type of rock that can generate petroleum. Source rock is one element of the petroleum system, and without source rock, oil and gas fields cannot exist. The ability of source rock is primarily evaluated based on three factors: the amount of organic matter, the type of organic matter, and the maturity level. Each of these is assessed using instruments such as elemental analyzers, Rock Eval analysis devices, and microscopes for measuring vitrinite reflectance, utilizing rock samples collected from the surface and cuttings obtained from wells as foundational data for oil and gas exploration. [Evaluation and Analysis] ■ Evaluation of organic matter quantity (TOC analysis) ■ Evaluation of organic matter type (Rock Eval pyrolysis analysis) ■ Evaluation of maturity level (vitrinite reflectance measurement) ■ Analysis of activation energy distribution *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or refer to the PDF materials, or feel free to contact us.
Our company utilizes geochemical analysis data obtained from gas composition analysis, carbon isotope analysis, and crude oil biomarker composition analysis to evaluate the formation environment, age, and maturity of the source rock that generates oil and gas, assess the condition and continuity of the reservoir, and evaluate the migration and accumulation processes of oil and gas into the reservoir. In exploration evaluation, this contributes to increasing the success rate of exploratory drilling, and in reservoir management, it aids in efficient oil layer development planning and avoidance of production disruptions. [Analysis and Evaluation] ■ Gas analysis (composition and isotopes) ■ GC-MS analysis of crude oil (biomarker analysis) ■ Evaluation of depositional environment, age, and maturity using biomarkers ■ Assessment of reservoir continuity (fingerprint analysis) ■ Migration and accumulation evaluation *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or refer to the PDF materials, or feel free to contact us.
At our company, in addition to the produced water from wells, we utilize various types of water for reservoir evaluation and operational trouble resolution, including spring water collected from surface surveys, geothermal water, wastewater used in mining operations, and river water collected for environmental survey purposes. Samples are pre-treated according to the analysis items, followed by wet analysis or instrumental analysis. In cases where instrumental analysis is difficult or when immediate analysis results are needed, qualitative and quantitative analyses of components are performed using the color of reagents or the amount of reagent dropped until a color change occurs. 【Features】 ■ Understand the condition of the reservoir to aid in reservoir development and production operations ■ Prevent operational troubles in advance and investigate causes when they occur ■ Assist in the exploration of new energy sources such as geothermal resources ■ Evaluate the environmental impact of resource development *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or feel free to contact us.
At Japan Petroleum Exploration Co., Ltd., we make the most of various petrological techniques and apply them to the exploration and development of oil and geothermal resources. We offer a wide range of analyses, starting with "thin section observation (blue resin impregnation)," which should be the first step in rock mineral analysis, as well as "X-ray diffraction analysis (XRD)" and "fluid inclusion micro-thermometry." [Exploration and Evaluation Work] ■ Thin Section Observation (Blue Resin Impregnation) ■ X-ray Diffraction Analysis (XRD) ■ X-ray Fluorescence Analysis (XRF) ■ Scanning Electron Microscopy (with Energy Dispersive X-ray Spectroscopy) ■ Fluid Inclusion Micro-Thermometry *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or feel free to contact us.
"Microfossil analysis" is used for determining the age and stratigraphy of sedimentary layers, comparing distant regions, and estimating depositional environments. By using multiple fossils, more detailed age estimates and comparisons can be made. Results can be obtained in some cases within a few hours from samples weighing just a few grams to 100 grams. Additionally, due to the rapid preprocessing and analysis, it can be utilized at drilling sites. 【Features】 ■ Analysis of foraminifera fossils, calcareous nannofossils, and diatom fossils ■ Determination of the age and stratigraphy of sedimentary layers ■ Comparison with distant regions and estimation of depositional environments ■ Rapid preprocessing and analysis ■ Greatly aids in estimating the distribution of oil and gas *For more details, please visit our company website / Technical Services (https://www.japex.co.jp/technology/service.html) or feel free to contact us.
