    Study Notes

    Hydrocarbon Exploration

    • Seeps and shows provide basic evidence of hydrocarbon generation in hydrocarbon exploration.

    Hydrocarbon Deposit Detection

    • Seismic surveys are primarily used to detect and determine the extent of hydrocarbon deposits.

    Initial Survey Method

    • A regional seismic survey is the initial survey method used in areas thought to contain hydrocarbons.

    Lead Evaluation

    • Features of interest, known as leads, are subjected to further exploration and analysis in hydrocarbon exploration.

    Pockmarks

    • Pockmarks in hydrocarbon exploration refer to depressions on the seafloor or sediment surface, often associated with hydrocarbon leakage or escape.

    Initial Survey

    • A regional seismic survey is initially conducted in areas suspected to contain hydrocarbons.
