The rocks must be like that so the petroleum can have somewhere to reside while underground, the more porous and permeable the host rock is, the more oil there well be in it, as long as there is oil in the area. think of it as trying to fill a bowl full of marbles with water. It fills a lot easier then the bowl filled with cement
Generally, yes. Igneous rocks are typically less porous than sedimentary rocks because they form from molten magma that cools and solidifies quickly, leaving minimal space for pores to form. Sedimentary rocks, on the other hand, are often composed of loose grains or fragments that can create more pore spaces within the rock.
It's because sedimentary rocks have big air spaces in them which makes them very porous, whereas igneous and metamorphic rocks are less porous, as the crystals are tightly packed.
Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.
Coal is typically found in sedimentary rocks such as sandstone, shale, and limestone. Petroleum is found in sedimentary rocks as well, usually in porous reservoir rocks such as sandstone or limestone that are capped by impermeable rock layers like shale or mudstone.
Sedimentary rocks, such as sandstone and limestone, are commonly associated with oil deposits. When organic matter accumulates and gets buried over time, it can transform into oil and become trapped in porous rock formations. These sedimentary rocks serve as reservoirs for oil extraction.

sedimentary rocks have layers showing the deposition of sediment at different time periods.sedimentary rocks consists of lots of small grains. these grains maybe weakly and together so the rocks are often porous and maybe soft and crumbly.sedimentary rocks often have fossils trapped with in them.sedimentary rocks consist of layers of lots of small particals.

Sedimentary rocks have numerous fossils
A rock formed from grains stuck together would be Porous
Research has shown that it is not always very easy to identify sedimentary rocks with the naked eye. It has been stated that sedimentary rocks are porous and may contain small holes. Also, if one is to rub the rock and small grains tend to come off it might also be sedimentary.
No, sedimentary rocks are generally not vesicular. Vesicular rocks are typically igneous rocks that contain gas bubbles trapped during cooling, creating a porous appearance. Sedimentary rocks form from the accumulation and compression of sediments, which do not typically contain vesicles.
not that often
Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.
They are called clastic sedimentary rocks.
Sedimentary rocks, and foliated metamorphic rocks form in layers.
