    types of petroleum traps

    Traps and Type of Traps

    traps


     Is ahigh point in the reservoir rock where the gas or oil is concentrated as it flows in an upward direction along the reservoir rock layer


    Traps is underground rock information that blocks the movement of petroleum 

    Traps found in sedimentary rock such as sandstones and limestones

    Type of traps 

    Structural trap



     types of petroleum traps Structural traps,stratigraphic traps,fault trap,anticline traps


    Formed by the deformation of the rock such a afolded arch 

    (dome or an anticline)
    or
    abreak 

    (afults)

    stratigraphic trap


     types of petroleum traps Structural traps,stratigraphic traps,fault trap,anticline traps

    Formed when the was originally deposited (in ariver channal or reef

    or

    when part of the reservoir was removed by erosion

    In the reservoir rock trap the fluids seperate according to their denesity the gas goes to the top , the oil to the middle and the water to the bottom

    Acommon reservoir rock is sandstone which is composed of sand grains.the pores are located in the spaces between the individual sand grains limestone,primarily formed by biological materials such as shell beds or reefs are also reservoir rocks 

    Some limestones are originally deposited with pore spaces
