Exploration & Geology

Exploration and subsurface activities involve locating hydrocarbon deposits and evaluating the geological formations that contain them. Techniques such as seismic surveying, well logging, and reservoir modeling guide drilling decisions and optimize production.

  • Trap
    29

    A trap is a geological configuration that allows significant quantities of petroleum (oil and natural gas) to accumulate and be retained in the subsurface. Without…

  • Velocity
    27

    Velocity in the context of petroleum exploration and geology refers to the speed at which seismic waves travel through subsurface rock layers. It is a…

  • Water Saturation
    26

    Water Saturation (Sw) is a fundamental petrophysical property that quantifies the fraction of pore space in a reservoir rock that is filled with formation water.…

  • Well Correlation
    30

    Well correlation is a fundamental interpretive technique in petroleum geology and exploration that involves the comparison of stratigraphic and lithologic data from multiple wells to…

  • Well Logging
    27

    Well logging is a fundamental technique in petroleum exploration and geology that involves recording detailed measurements of rock and fluid properties within a borehole. These…
