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

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
