Study Notes
Petrophysics
- The main focus of petrophysics is the study of reservoir properties and their interactions with fluids.
Reservoir Characteristics
- A reservoir must contain porous and permeable material, such as sandstone or carbonate rocks, to store fluids.
Essential Reservoir Properties
- The two crucial properties for the storage and transmission of fluids in a reservoir are porosity and permeability.
Efficient Oilfield Development
- Integrated analysis of geological, geophysical, and petrophysical data is required for efficient development, management, and prediction of future performance in an oilfield.
Petrophysical Contributions
- Petrophysics contributes to the study of hydrocarbon reservoirs by characterizing the physical and chemical properties of reservoir rocks and their interactions with fluids.
Minerals
- Minerals are naturally occurring inorganic solids with a specific chemical composition and a crystalline structure.
Chemical Analysis
- The method used to analyze the chemical composition of the sandstone rocks involved fusing the rocks with lithium before analysis.
Sample Preparation
- The rocks were fused with lithium to improve the reliability of the chemical analysis results.
Limitations of SEM-XRF Analysis
- The limitation of the scanning electron microscope X-ray fluorescence (SEM-XRF) analysis is that it only provides information on the surface composition of the sample.
Importance of Comparative Analysis
- The difference between the chemical analysis of the total sample and the spot surface analysis is significant because it reveals possible variations in chemical composition between the surface and bulk of the sample.
