Crude Oil Assay Analysis for Raw Oil Collection
Raw oil characterization is an important stage in the oil and gas industry to know the quality, composition and the potential for oil crude oil processing. Through the Crude Oil Assay, various characteristics of physical and chemical crude oil can be evaluated thoroughly as a basis for determining the equilibrium of raw materials, estimating the potential for processing, as well as supporting operational and commercial decisions.
PT Hidea Core supports testing and consulting labs for oil & gas industries via petroleum analysis services. The test of the oil crude can cover various parameters, starting with density, API gravity, visibility, sulfur content, water content, up to the characteristics of hydrocarbons like Asphaltenes and SARA. The selection of parameters is based on the characteristics of the sample and purpose of the analysis needed.
Top of the Crude Oil Assay for Oil & Gas Industries
For oil exploration and production companies, refinery, or raw oil trade companies, the data of the crude oil characterization is an essential aspect of quality evaluations and economic value of products. Enforcement Crude Oil Assay gives the following strategic benefits:
- Crude Oil Quality Event
Giving information about the physical characteristics and chemical chemistry of raw oil, including density, API gravity, visibility, sulfur content, and the nature of immunities as a basis for the quality evaluation of oil crudes. - Feedstock Assessment Resfinery
Help evaluate the characteristics of the oil cruil as the raw materials of refinery. Information about the composition and range of the boiling point can be used to support the feedback selection consideration and processing process. - Product Yield Estimation
Data distillation and characterization fractions can be used to evaluate product distribution based on the range of boiling points, so it helps estimate the potential fractions like naphtha, kerosene, diesel, and oil gas vacuum. - Commercial Value Assessment
It's characteristic like API gravity, sulfur content, TAN, and metal content can become supporting information in quality evaluations and crude commercial considerations. - Operation Risk Evaluation
Information about wax, asphaltens, water, sediment, and other input components can help identify the characteristics of the oil crudes that need to be noticed in the process of production, transportation, storage and processing.
Test Parameters Crude Oil Assay
The test of Crude Oil Assay covers various parameters used to describe the characteristics of crude oil. In general, those parameters can be grouped into physical characteristics, chemical composition, contaminant content, as well as distillation characteristics.
Here are some parameters that are generally used in characterization of crude oil:
| Testing Parameters | Race Method | Analysis Function |
|---|---|---|
| Density / Specific Gravity | ASTM D1298 | Specific gravity of crude oil. |
| Gravity API | ASTM D1298 | It classifies heavy characteristics or crude oil lightweight. |
| Kinematic Vistolity | ASTM D445 | Evaluate the characteristics of the oil flow at a specific test temperature. |
| Pour Point | ASTM D97 | Determines the lowest temperature when the sample still shows the ability to flow according to the method. |
| Sulfur Content | ASTM D4294 | Determines the total content of sulfur in oil crudes. |
| Water Content | ASTM D4006 | Determines the water content in crude oil. |
| Sediment Content | ASTM D473 | Determines the sediment content contained in oil crudes. |
| Salt Content | ASTM D3230 | Evaluate the salt content in crude oil. |
| Total Acid Number (TAN) | ASTM D664 | Determines the acidity rate based on the number of bases required to neutralize the acidic components in the sample. |
| Asphaltens Content | ASTM D6560 | Determines the content of asphaltens based on the exception principle of using a solvent. |
| SARA Analysis | Matching chromatography method | Character fractions of saturates, roostics, resins, and asphaltens. |
| Metals Content | ASTM D5708 | Determines specific metal content like Nickel and Vanadium. |
The selection of methods and testing parameters needs to be adjusted to the characteristics of the sample, purpose analysis, as well as the specifications that customers require. Not the whole parameter must be tested in any need of cruise oil assay.
Syntax Analysis and characterization Crude Oil Faction
One of the important parts in the Crude Oil Assay is the characteristic evaluation of distillation to know the distribution of raw oil fractions based on the range of boiling points (binding range). This data gives us an idea of the potential distribution of products that can be obtained through processing in refinery.
Some of the methods used in characterization Crude Oil distillation include:
- ASTM D2892 - Dititlation of Crude Petroleum (15-Theoretical Platte Columbn)
Used for distillation of petroleum crudes using columns with a specific theoretical plate number. This method supports characterization of the scaling point range and the collection of crude oil fractions. - ASTM D5236 - Synthelation of Heavy Hydrocarbon Mixtures (Vacuum Potstill Method)
Used for distillation of heavy hydrocarbons mixed with vacuum pressure. This method is relevant to heavy fractions characterization that require special distillation conditions.
The distillation results can be used to evaluate fractions distribution like gas and LPG, naphtha, kerosene, diesel, oil gas, as well as residue. That information becomes one of the basics in evaluating the potential processing and feedstock characteristic refinery.
Kind of Analysis Support Crude Oil Characterization
In addition to testing physical and chemical parameters, the characterization of the oil crude can be equipped with special analysis to acquire more detailed information about the composition and behavior of hydrocarbon.
- SARA Analysis - Identify the four main groups of crude oil components, which are the saturates, the aromacs, the Resins, and the Asphaltens to evaluate the characteristics of raw oil composition.
- Asphaltens Analysis - Determines the content of asphaltens associated with the characteristics of heavy fractions and potential problems during production and processing.
- Wax Analysis - Evaluate the wax content and the characteristics of building wax that can affect the production and transportation of the oil crude.
- Sulfur Analysis - Determines the total content of sulfur as part of a quality evaluation and characteristic of raw oil processing.
- Metals Analysis - Identifying certain metal content can be considered in feedstock quality evaluations and refinery processes.
The analysis of those supporters can be selected according to the need for characterization and not always be a mandatory part of any package crude oil assay.
