Agenda
1) Sedimentary Rock .

2) Sandstone .

3) Reservoir .

4) Sandstone as reservoir rock

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water.

Sedimentary rock formation
Begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth’s surface they begin the long slow but relentless process of becoming sedimentary rock.
Weathering ,Erosion,Transportation and Deposition

classification of Sedimentary rocks
Chemical sedimentary Rocks
Organic sedimentary rocks
Clastic sedimentary Rocks
Sandstone
- Sandstone is clastic sedimentary rock.
- Most sandstone is composed of quartz and or feldspar because these are the most common minerals in the Earth's crust.

Formation
- layers of sand accumulate as the result of

sedimentation

- sand becomes
sandstone
when it is compacted by pressure of
overlying deposits
.

Properties
Reservoir
Sandstone As Reservoir Rock
Geometry
- Generally found it at middle east .
- 25 meters thick .
- Less than 250 km2 in area .
Properties
Porosity
- Consists of the tiny spaces in the rock that hold the oil or gas.


- Sandstone porosity is on the range of 10-30%
(Primary porosity)
- The grains of sandstone are similar in size .
( Increase porosity )
- It is really very much like a
sponge .
Permeability
There is no “ocean” of oil underground!
- characteristic that allows the oil and gas to flow through the rock .
- Difference between porosity and Permeability .
- Sandstone have high Permeability .
Relation between porosity and depth

-

Inverse relation

Porosity
Reaction with acids
Pressure
Quartz is very strong .
Increase porosity
