Oil and gas exploration, or generally called as hydrocarbon explorations is the expression used by geologists to look for oil and gas. Drilling is expensive and as such hydrocarbon explorations are performed to identify possible places which contain these deposits while limiting cost and reducing its effect on the environment.

Hydrocarbon Exploration

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

Seismic survey is one of the popular techniques that geologists use in ascertaining if hydrocarbons exist particularly in deep water surveillance. The process uses sound to determine the degree of these stone formations in the deep water. Many companies make use of vibrator trucks or even small explosive charges on land and record the noise by means of a geophone.

Aside from seismic surveys, geologists may also make use of offshore surveys which involves the use of compressed air to make large bubbles which burst upon reaching the surface area. The sound waves from the burst will subsequently travel under and reach the stones where the vibrations are then listed by hydrophones. As each stone generates different sound waves, geologists will also be able to identify the rock type that exists from the deep.

Some explorations can also use magnetometers and gravimeters to assess the planet's gravity pull at the surface whereas geochemical prospecting involves the measuring of pure gases using high-tech devices.

Remote Sensing can also be one of the techniques that geologists utilized to ascertain the construction of the exploration site. An aerial photograph is done in order to map the surface area of the proposed site, showing important details such as the soil type, plant, minerals and other capabilities.

In certain cases where data is restricted, some oil and gas companies also execute a wildcat well particularly in regions that aren't explored before. tucumann provide mining companies information on the website and whether petroleum or natural gas are available.
