Geophysics

Introduction

Geophysics is the application of physics to the study of the structure and dynamic behaviour of the earth and other planets. Geophysicists are specialists in tectonics, seismology, planetary magnetic field formation, and mass distribution analysis. They understand how to trace the underlying structure of the planet and its previous history including gravimetrics, measuring seismic transmission, changes to the magnetic field, and the history of the magnetic field as recorded in rocks. Strength, elasticity, stiffness, crystal structure, radioactivity, and temperature qualities of rock on a planet are all things they’re familiar with. Geophysicists use seismic, gravitational, magnetic, and electrical data collecting methods to investigate the structure and composition of zones under the earth’s surface. Exploration geophysics, which deals with the hunt for Earth’s resources, and global geophysics, which employs the same techniques to study the Earth as a whole, including earthquakes, magnetic fields, and other phenomena, are the two primary sections of geophysics. Seismology and seismic interpretation, borehole geophysics, mineral exploration, engineering geophysics, environmental or groundwater geophysics, or computer processing and software development are all areas where geophysicists specialise. Geophysics is concerned with earthquakes, the birth and destruction of planets, volcanic eruptions, the movement of the tectonic plates at the Earth’s surface and also with the gradual rise of land once covered by ice sheets.

Nature of work

  • plan projects ahead of time, before going on site
  • make strategies for data collection
  • select appropriate seismic measurement and data-processing methods
  • deploy seismometers at numerous sites throughout the world with equipment
  • In order to spot abnormalities, monitor the recording equipment’s behaviour.
  • Data management, quality control, and communication between the office and field sites may all be done with computers.
  • interpret and map 2D and 3D seismic data
  • calculate reservoir quantities 
  • analyse prospective oil and gas output 
  • work closely with a small team of scientists and other personnel who may be gone in the field or offshore for many weeks at a time 
  • create charts and reports on acquired seismic data for the team, clients, senior management, or partners during meetings and presentations
  • produce documentation and work logs
  • give geophysical assistance as well as technical advice and guidance
  • stay up to date on new and upcoming technologies
  • strive to enhance existing data collecting and mathematical processing approaches while also developing new approaches and methods
  • adhere to budgetary, resource, and time restrictions.

Scope of geophysics in Pakistan

There are several firms operating in Pakistan, all of which are looking for new and fresh talent. There are several exploration firms operating in Pakistan, and these businesses are uncovering new wells virtually every month. Every government agency that wants to set their foundation or build a new road town will require the services of a geologist or geophysicist. In Pakistan so many new companies are working like British petroleum, Halliburton, Land mark, China national logging, BGP, Slb.Whereas the Pakistani companies working in that field are OGDCL, Petroleum exploration limited, Pakistan oil limited, new horizon and so on.

How to become a geophysicist

To become a geophysicist, you need to complete your intermediate in the science stream and then enrol yourself in a bachelors program in geophysics or relevant degree. Further specializations can be done on postgraduate level. Start early in your career by applying for internships in prestigious organizations and building up your experience.
