Origin of Petroleum
• Oil is a fossil fuel that is formed from the remains of
tiny plants and animals, known as plankton that died
in ancient seas between 10 million and 600 million
years ago.
• The plankton fell to the bottom of the sea and after
decaying, the organisms formed sedimentary layers.
• In the layers, little or no oxygen is present and this
allows microorganisms to break down the remains
into carbon-rich compounds that form organic layers.
Origin of Petroleum
• The organic material mix with the sediments to
form fine-grained shale, or source rock.
• As the sedimentary rocks layer, they exert
extreme heat and pressure to distill the organic
material into crude oil and natural gas.
Migration of Petroleum
• The oil then flows from the source rock and
accumulates in thicker, more porous limestone
or sandstone known as reservoir rock.
• When the earth moves the oil and natural gas is
trapped in reservoir rocks, which are between
layers of impermeable rock, or cap rock– usually
granite or marble.
• The whole process takes millions of years.
Geophysical Prospecting Methods
1) Magnetic Surveying :
M1 M2
Where :
F=a
r2
Fmagnetic Force.
A–
constant generally unity.
M1 & M2 – strength of the respective poles.
r–
distance between poles.
2) Gravity Surveying :
M1 M2
Where :
F=G
d2
F – Gravitational force between two
point masses M1 & M2
d – Distance between M1 & M2
G – Gravitational constant

( 6.67 × 10 m / kg S )
3) Seismic Surveying .
3) Seismic Surveying
• Oil geologists examine surface features, surface rock,
reservoir rock, entrapment, satellite images, sensitive
gravity meters and manometers.
• The most common technique for finding reserves is
seismology which uses shock waves that interpret
waves reflected back to the surface.
• Despite all the technologies, modern oil exploration
methods are only 10 percent successful.
4) Remote Sensing:
• Collection of data without the actual contact of
the object . ( aeromagnetic & gravity ) .
• Useful for topographic mapping specially in
desert areas
• When used in conjunction with other
techniques such as gravity & magnetic , it may
delineate anomalies that deserve further
attention on the ground
• The Government and Oil companies
usually assign finding oil to contracted
geologists.
