NURSYAHIRA ABD HAMID ASSIGNMENT 1 Explain the concept and purpose of the geochemical‚ gravity‚ electromagnetic and magnetic surveys. 1. Concept and purpose of geochemistry Petroleum geochemistry has played an important role in many areas of exploration and production for fossil fuels. Many of the more recent developments can be seen to have developed in parallel with developments in analytical chemistry such as gas chromatography and gas chromatography−mass spectrometry. For the past two decades
