Electrogeochemical surveys, bacterial leach, and other advanced geochemical exploration survey techniques are described.
Some exploration, survey, economic study, and design work was done, but the government, in the midst of the Chinese Civil War, halted work in 1947.
Types and various geochemical exploration surveys are detailed with examples.
A large number of hydrocarbon exploration surveys have been carried out resulting in geological, geophysical, and well log data sets of the Cambay basin.
Following on from surface exploration surveys performed during the 1970s and early 1980s, exploration drilling was carried out in the Tendaho Rift, in Central Afar (Ethiopia), from October 1993 to June 1995.
In the subducting area, the accretion prism or the sedimentary wedge can be observed in the cross-sections of the exploration surveys (e.g., Nakanishi et al., 1998, 2002a, b; Kodaira et al., 2002).
The most important structure analyzed in the IGME Montorio geological map sheet during hydrocarbon exploration surveys is associated with the called Falla de Hontomín, beneath the subsoil of the same name' town.
Deploying three-component, short-period (4.5 Hz) sensors with a station spacing of 6 km, we constructed six linear OBS arrays in the northwestern Pacific for seismic exploration surveys during 2009 and 2010 (Fujie et al. 2013).
Just weeks later a survey ship commissioned by the Philippine Department of Energy was conducting oil exploration surveys in Reed Bank, just 80 nautical miles west of the Philippine island of Palawan when two Chinese patrol boats confronted it and threatened to ram it, forcing it to withdrawal (The Economist 2011).
Before this experiment, crustal velocity structure and subducting slab structure had been studied by p-wave exploration surveys (e.g. Nakanishi et al., 1998, 2002a, b; Kodaira et al., 2002) and, using earthquake records, by the receiver function method (e.g. Yamauchi et al., 2003).
The main reservoir engineering data discussed in this paper were collected during drilling and testing of the above four wells, three of which are located inside the Dubti Cotton Plantation, in which a promising hydrothermal area was identified by surface exploration surveys.
