Q4. What are the specifications provided for each core sample?

Ans: Each core sample comes with detailed specifications, including lithology, depth, porosity, permeability, and any other relevant data for accurate analysis.

Q5. What is Sandstone made up of?

Ans: Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles or grains, which are primarily quartz or feldspar. These grains are typically cemented together by various natural cementing materials, such as silica, calcium carbonate, or iron oxide. The specific composition of sandstone can vary, leading to different colors and textures in the rock. Additionally, other minerals and organic materials may be present, providing further diversity in sandstone’s appearance. It holds a huge significance in the petroleum industry and Sandstone core sample widely used by Texas Petroleum Researchers for their research work.

Q6. Why is core sampling needed?

Ans: Core sampling is an essential geological and engineering technique used to extract cylindrical samples (cores) from subsurface rock or soil formations. This method is employed for various purposes:
Geological Analysis: Core samples help geologists study the composition, structure, and history of the Earth’s crust, revealing information about past environments and events.
Resource Exploration: In the oil and gas industry, core sampling assists in identifying potential hydrocarbon reservoirs and estimating their productivity.
Engineering Projects: Engineers use core samples to assess the stability and load-bearing capacity of rocks and soils before construction, ensuring safer and more reliable structures.
Environmental Studies: Core sampling aids in understanding groundwater levels, contaminant distribution, and geological characteristics of an area, facilitating environmental assessments.

Q7. How do you make a core sample?

Ans: Creating a core sample involves the following steps:
Drilling: Specialized core drilling equipment, such as diamond-tipped drill bits, is used to extract cylindrical rock or soil samples from the subsurface. The drill is rotated and advanced into the ground to obtain continuous cores.
Retrieval: Once the core has been drilled, it is carefully extracted from the borehole and stored in a core barrel to preserve its integrity and prevent contamination.
Labeling and Logging: Each core is labeled with relevant information, including the depth at which it was obtained, date, and location. Geologists and engineers then log the core, recording visual observations and any distinct features.
Transport and Storage: Cores are transported to a laboratory or storage facility under controlled conditions to maintain their quality and prevent damage.

Q8. What is core testing?

Ans: Core testing involves a series of laboratory analyses and physical tests conducted on core samples to gather valuable information about their properties. The tests vary depending on the purpose of the study and may include:
Physical Properties: Measurements of density, porosity, permeability, and moisture content to assess the rock’s physical characteristics.
Mineralogical Analysis: Identifying the mineral composition of the core through techniques like X-ray diffraction (XRD) and petrographic microscopy.
Chemical Analysis: Determining the chemical composition of the core to understand its elemental and mineralogical makeup.
Mechanical Testing: Evaluating the rock’s strength, elasticity, and deformation behavior to assess its suitability for construction or engineering purposes.
Fluid Flow Analysis: Assessing how fluids (e.g., oil, gas, water) flow through the rock, which is crucial for oil and gas reservoir evaluation.

Q9. What is core sample analysis?

Ans: Core sample analysis is a scientific method used to examine and study geological formations and subsurface materials by extracting cylindrical samples, known as cores, from the earth’s crust. These cores are typically obtained through drilling techniques and provide valuable information about the composition, structure, and history of the rock or sediment layers.

Q10. What is the core cutting test?

Ans: The core cutting test is a procedure carried out on core samples to obtain smaller, manageable sections for further analysis or preservation. The process involves:
Slicing the Core: The cylindrical core sample is cut longitudinally (parallel to its axis) into smaller sections using a specialized core cutting machine equipped with a diamond saw or another cutting tool.
Sampling and Preservation: From these sections, specific samples can be taken for different tests while ensuring the remaining core is preserved intact for additional analyses or reference.
Labeling and Storage: Each cut section and its corresponding samples are labeled with relevant details for identification purposes and stored appropriately to maintain their integrity.
The core cutting test facilitates more detailed investigations of specific features, mineralogical variations, and geotechnical properties present within the core sample.

Q11. How are the core samples packaged for shipping?

Ans: Our core samples are carefully packaged to ensure safe transit. We use sturdy containers and protective materials to prevent any damage during shipping.

Q12. Who utilizes core sample analysis?

Ans: Core sample analysis is conducted by a diverse group of professionals, including geologists, geochemists, paleontologists, environmental scientists, mining engineers, petroleum engineers, and researchers from various earth and environmental science disciplines.
