  • 9. 

     Identify the type of traps which can be seen on the seismic section.

  • 10. 

    Propose minimum one attributes to confirm the DHI anomalies from seismic section.

  • 11. 

    Identify the possible geological feature can be seen from the time slice of this seismic section?

  • 12. 

    Propose minimum one attributes to delineate this geological feature. Justify your answer.

  • 13. 

    Choose the incorrect statement: What is the importance of knowing the seismic header information?

    • A.

      Provides the location information of the seismic survey

    • B.

      The header provides amplitude anomalies of the seismic section

    • C.

      Provides the no of streamers

    • D.

      Provides the coordinate system

    Correct Answer
    B. The header provides amplitude anomalies of the seismic section
    Explanation
    The given answer is incorrect because the seismic header information does not provide amplitude anomalies of the seismic section. The header primarily provides information such as the location of the seismic survey, the number of streamers used, and the coordinate system used. Amplitude anomalies are typically analyzed and interpreted from the seismic data itself, not from the header information.

    Choose the correct statement: Provide a workflow (step(s)) to import the seismic data from segy to zgy format?

    • A.

      Data loading by assigning the correct byte location -> choose the correct UTM based on the seismic header -> realize the data to zgy format

    • B.

      Directly load the data from segy

    • C.

      Data loading by assigning the correct byte location -> changing the seismic header -> realize the data to zgy format

    • D.

      Directly get the zgy format

    Correct Answer
    A. Data loading by assigning the correct byte location -> choose the correct UTM based on the seismic header -> realize the data to zgy format
    Explanation
    The correct answer is "Data loading by assigning the correct byte location -> choose the correct UTM based on the seismic header -> realize the data to zgy format". This answer suggests that the process of importing seismic data from segy to zgy format involves loading the data by assigning the correct byte location, selecting the appropriate UTM (Universal Transverse Mercator) based on the seismic header, and then converting the data to the zgy format.

  • 15. 

    What is the coordinate system used in this survey?

    • A.

      Syntrak 960-24 System

    • B.

      UTM System

    • C.

      Petronas Carigali Sdn .Bhd

    • D.

      Sepat and Laho

    Correct Answer
    B. UTM System
    Explanation
    The UTM (Universal Transverse Mercator) system is used in this survey. UTM divides the Earth into 60 zones, each spanning 6 degrees of longitude. It provides a coordinate system that is widely used for mapping and surveying purposes, allowing accurate and consistent measurements to be made across different locations.

  • 16. 

    How many streamers were used in the acquisition?

    • A.

      18.75

    • B.

      480

    • C.

      8

    • D.

      6000

    Correct Answer
    C. 8
    Explanation
    The correct answer is 8. This suggests that there were 8 streamers used in the acquisition process.

  • 17. 

    Identify the phase and polarity of the seismic section

    • A.

      Zero phase, American polarity

    • B.

      Zero phase, European polarity

    • C.

      Minimum phase, European polarity

    • D.

      Minimum phase, American polarity

    Correct Answer
    A. Zero phase, American polarity
    Explanation
    The seismic section is described as having zero phase, which means that the seismic waves are in perfect alignment with the source wavelet. This allows for easier interpretation of the seismic data. The polarity is described as American, which refers to the convention of representing positive amplitudes as upward deflections on a seismic trace. This is in contrast to European polarity, where positive amplitudes are represented as downward deflections.

    The seismic section below is located in offshore Sabah. Identify what is the type of DHI you can identified in these images?

    • A.

      Dim Spot

    • B.

      Bright Spot

    • C.

      Flat spot

    • D.

      Bright Amplitude

    Correct Answer
    C. Flat spot
    Explanation
    A flat spot is a type of direct hydrocarbon indicator (DHI) that can be identified in seismic sections. It appears as a relatively horizontal, continuous reflection that is caused by the presence of a hydrocarbon accumulation. The flat spot occurs due to the contrast in acoustic impedance between the hydrocarbon-filled reservoir and the surrounding rock layers. This results in a distinct, flat reflection on the seismic data. The presence of a flat spot can indicate the potential presence of hydrocarbons and is often used as a target for exploration and drilling activities.

    How many geophones were used in the acquisition?

    • A.

      480

    • B.

      18.75

    • C.

      6000

    • D.

      8

    Correct Answer
    A. 480
    Explanation
    The correct answer is 480. This suggests that 480 geophones were used in the acquisition process.
