why does the limestone stores petrol ?
Answers
Explanation:
Although the porosity and permeability are poor, shale, silt stone, limestone can even act as reservoir due to fractures in the rock body (secondary porosity – secondary permeability). For example, an oil field in Florence, Colorado which is having shale (Lower–Upper Cretaceous) as reservoir rock.
A natural reservoir is a natural reservoir for oil, gas and water, within which they can circulate and whose shape is determined by the ratio of the reservoir to the poorly permeable rocks that contain it (the reservoir). There are three main types of natural reservoirs: reservoir, massive and lithologically limited on all sides.
A reservoir reservoir is a reservoir that has a wide area distribution and is limited in the roof sole by poorly permeable rocks.
There are various options for reservoir reservoirs. They can be represented by well-maintained homogeneous collectors in terms of area and capacity. It is not uncommon for a reservoir layer, regionally sustained over large areas, to be wedged to the arches of individual brachianti-clinal folds. The reservoir layer can also be represented by several interlayers that communicate with each other and are subject to abrupt lithofacial substitutions.
