Oil And Gas Exploration Techniques

May 30, 2018

Gas and oil exploration, or commonly called as hydrocarbon explorations is the expression used by geologists to search for petroleum and natural gas. The mining enables mining and oil companies to harvest natural gas and hydrocarbons from different areas of the planet. Drilling is expensive and therefore hydrocarbon explorations are performed to identify possible areas which contain these deposits while limiting cost and reducing its impact on the environment.

Hydrocarbon Exploration

Before a drill location is identified, geologists must assess the region and ensure that five factors exist - source rock, reservoir, migration, trap and seal or cap stone. As explorations are costly and expensive, these variables should be current before any drilling is finished. Once the factors are believed, geologists employ several techniques to ensure the success of this drilling. The first methodology involves geophysical survey or seismic survey.

Seismic survey is one of the popular methods that geologists use in determining if hydrocarbons exist especially in warm water surveillance. The process makes use of sound to find out the degree of the rock formations in the deep water. Many businesses take advantage of vibrator trucks or even small explosive charges on property and record the sound by means of a geophone.

Besides seismic surveys, geologists can also use offshore surveys which involves the use of compressed air to make massive bubbles that burst upon reaching the surface region. The sound waves from the burst will subsequently travel under and reach the rocks where the vibrations are subsequently recorded by hydrophones. As every rock produces different audio waves, geologists are also able to identify the rock kind that exists from the deep.

Some explorations may also make use of magnetometers and gravimeters to assess the earth’s gravity pull in the surface whereas geochemical prospecting requires the measuring of natural gases using high-tech instruments.

Remote Sensing can also be one of those techniques that geologists utilized to determine the construction of the exploration site.

In tucumann where data is limited, some gas and oil companies also execute a wildcat well particularly in regions which aren’t explored before. The molds provide mining companies information on the site and whether oil or natural gas are available.
