Oil and Gas
Oil and gas exploration is the search by petroleum geologists and geophysicists for deposits of hydrocarbons, particularly petroleum and natural gas, in the Earth’s crust using petroleum geology. 

The Global Seismic Survey Market is estimated to be USD 1.91 Bn in 2023 and is expected to reach USD 2.38 Bn by 2028, growing at a CAGR of 4.48%.

The Global Seismic Survey Market is segmented based on Service, Technology, and Geography, By Service, the market is classified into Data Acquisition and Data Processing & Interpretation. By Technology, the market is classified into 2D, 3D, and 4D.

The process of oil and gas exploration typically consists of four stages: search and exploration, well construction, production, and abandonment. 

Exploration in the Oil and Gas industry refers to the research and discovery of potential drilling and extraction sites and reserves for crude oil. This is done by conducting multiple surveys, analyses, and tests on the areas of interest.  

Muayad Alsamaraee, and MD-Consortium and JAI team in Jordan Since 2003 they invented a solution for that by using magnetic survey, one of the tools used by exploration geophysicists in their search for mineral-bearing ore bodies or even oil-bearing sedimentary structures. 

Magnetic surveys are a geophysical method to image anomalies in the earth's magnetic field caused by source bodies within the sub-surface. Oil and gas exploration use magnetic anomalies to detect faults and igneous intrusions.

Based on the characteristics of the geomagnetism, numbers of methods have been developed. The principal idea is employed based on the matching algorithms, such as MSD (Mean Square Difference), MAD (Mean Absolute Difference), ICCP (Iterative Closest Contour Point Algorithm), traditional matching algorithms strongly depend on a priori geomagnetic map, which is quite challenging to acquire during practice.  the missions of navigation and tracking systems in underwater, overwater and/or Air environments.

Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.

As water flows around the planet, these ions are deflected by the Earth's magnetic field – positive ions are pushed one-way, negative ions the other. This builds up volumes of positively and negatively charged water, sometimes on a scale of thousands of kilometers. 

The geomagnetic field of the earth is very similar to the field of a bar magnetic and has played a major part in navigation over the centuries. By using a compass needle which aligns itself with the magnetic poles of the earth, navigators were able to determine which direction was North and which was South.

Magnetic anomaly navigation uses scalar magnetometers as sensors to measure differences in magnetic fields. Comparing these measurements with magnetic-field maps can provide information resulting in position determination. 

A marine magnetic survey is the measurement of Earth's magnetic field intensity or its components (such as vertical component) along a series of profiles over an area of interest with the objective of measuring the magnetism of the ocean floor.

Humans do not have a magnetic sense, despite having a cryptochrome (cry2) in the retina which is magneto sensitive when exposed to light. A 2019 study found that magnetic fields do affect human alpha brain waves, but it is not known whether this results in any change in behavior.

Gravity and magnetic anomalies are defined as the deviation of the observed quantities, i.e., gravitational acceleration (or simply gravity) and magnetic flux density, respectively, from the expected value of a reference Earth.

The source of these anomalies is primarily permanent magnetization carried by titanomagnetite minerals in basalt and gabbro’s. They are magnetized when ocean crust is formed at the ridge. As magma rises to the surface and cools, the rock acquires a thermoremanent magnetization in the direction of the field.

A magnetic anomaly is the change in magnitude of the earth's magnetic field with respect to the expected value for that location. Large volumes of magnetic materials will change the intensity of the earth's field. The units of magnetic anomalies are nanotesla (nT) or the equivalent gamma.
