To lower the drill stem, the tubing, the casing, or the sucker rods into the wellbore.
The accurate measurement and recording of certain physical quantities of the Earth’s crust. geophysical methods are used (e.g. seismic) to locate probable reservoir structures capable of producing commercial quantities of natural gas and/or crude oil
A well in which production of oil /gas has decreased and production of water has increased
A geographic area where the gravitational attraction is significantly higher or significantly lower than normal.
A person who studies the physics of the earth. Geophysicists measure, examine, and explore the physical properties of earth, from below the ground to the atmosphere, from the depths of the ocean to the tops of volcanoes. Geophysicists use the principles of physics, mathematics and geology to study the surface and internal composition of the earth. Exploration geophysicists look for oil, natural gas, water and minerals for economic exploitation and for environmental projects
Concept that there is still a lot of interesting oil to be developed from the geological point of view around the world but that many areas are – geopolitically – closed to international oil companies, so that in fact they are not running out of oil but running out of places to drill
