The Goal of Geophysical Exploration Methods
The goal of oil and gas exploration is to find hydrocarbon accumulations in commercial quantities. Petroleum geoscientists seek information from multiple sources in order to evaluate the numerous Elements and…
Petroleum exploration
There are some requirements to meet a petroleum reservoir: 1. Source Rock 2. Reservoir Rock 3. Hydrocarbon Trap Source rock maturity for the petroleum reservoir depends on pressure and temperature during the lithification…
How does oil impact marine life?
Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird's feathers, thus exposing these creatures to the harsh elements. Without the…
Depositional environments
Sedimentary rocks are formed by 5 processes, there are erosion, weathering, transport, deposition, and diagenesis process (Boggs, 1991). These 5 processes with 4 types of rocks make up a cycle that is…
Accumulation in reservoir beds
The porosity (volume of pore spaces) and permeability (capacity for transmitting fluids) of carrier and reservoir beds are important factors in the migration and accumulation of oil. Most conventional petroleum accumulations have been found…
Rich Petroleum Source Rocks
Distribution of major petroleum sources rocks in space and through time has important implications for the global budget of petroleum resources. Although there is evidence for non-organic origin of methane,…
HOW IS PETROLEUM FORMED?
Most of the oil and gas deposits on the Norwegian shelf originate from a thick layer of black clay that currently lies several thousand metres under the seabed. The black…
Source Rock Hydrocarbon Generation
The formation of hydrocarbon liquids from an organic rich source rock with kerogen and bitumen to accumulates as oil or gas. Generation depends on three main factors: the presence of organic…
PETROLEUM SYSTEMS AND ELEMENTS OF PETROLEUM GEOLOGY
Petroleum system is a core concept of petroleum geology-the study of oil and gas formation and exploration with its associated processes such as oil origin, occurrence, migration and their accumulation-which…
THE ROCK CYCLE
Rocks at the surface of the earth are of many different ages. They range from over three billion years old to less than one million years old. We know that one of…
