Mineral exploration — is the process of finding ore (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of… … Wikipedia
Earth exploration — Introduction the investigation of the surface of the Earth and of its interior. By the beginning of the 20th century most of the Earth s surface had been explored, at least superficially, except for the Arctic and Antarctic regions. Today the… … Universalium
Gamma ray logging — is a method of measuring naturally occuring gamma radiation to characterize the rock or sediment in a borehole. It is sometimes used in mineral exploration and water well drilling, but most commonly for formation evaluation in oil and gas well… … Wikipedia
undersea exploration — Introduction the investigation and description of the ocean waters and the seafloor and of the Earth beneath. Primary objectives and accomplishments Included in the scope of undersea exploration are the physical and chemical… … Universalium
Resistivity logging — is a method of characterizing the rock or sediment in a borehole by measuring its electrical resistivity. Resistivity is a fundamental material property which represents how strongly a material opposes the flow of electric current. In these logs … Wikipedia
Hydrocarbon exploration — Onshore Drilling Rig Hydrocarbon exploration (or oil and gas exploration) is the search by petroleum geologists and geophysicists for hydrocarbon deposits beneath the Earth s surface, such as oil and natural gas. Oil and gas exploration are… … Wikipedia
well logging — the process or technique of recording a well log. * * * ▪ mining field technique used in mineral exploration to analyze the geologic formations penetrated by a drill hole. If the hole has been drilled by using coring techniques, the core… … Universalium
Sonic logging — shows a formation’s interval transit time, designated Dt . It is a measure of a formation’s capacity to transmit sound waves. Geologically, this capacity varies with lithology and rock textures, notably porosity.Quantitatively, the sonic log is… … Wikipedia
