Geological exploration methods
The methods and
procedures followed in geologic surveying depend upon whether the survey is
reconnaissance or detailed (geological, topography and structure mapping).
Reconnaissance
surveying: is for the purpose of determining the oil prospects of a relatively
large area in a limited space and time. A preliminary survey, usually executed
rapidly and at relatively low cost, prior to mapping in detail and with greater
accuracy.
Detailed geological survey: Based on these
available maps, the geologist must make his own map contains all the geologic
and economic data that were obtained. In the search for stratigraphic traps,
the geologist must identify the environment of deposition, possible reservoir
rocks, but of possible source and seal rocks as well. He also determines the
source of clastic sediment and the direction of transport. The field
party should also collect stratigraphic data, as well as the geologic and
structural maps..... Read More.
