Petroleum Geology is the branch of economic geology, which deals with the emergence and exploitation of oil and gas fields. Related fields include discovery of petroleum geochemistry and geophysics.
The related areas in oil recovery petroleum and chemical engineering are.The goal of Petroleum Geologists is to find traps and accumulations of petroleum. The case must be defined not only, but must be present with presence of other conditions, such as source and reservoir rocks. To find these traps, the geologists have to rely on information and data through underground drilling exploratory wells and collecting data obtained by geophysical investigations.
These data, once interpreted and used to represent in order to construct maps, cross sections and models used to close or to actual surface configurations that may contain oil.Such representations are the prospects for drilling.Major efforts in petroleum geology in engineering are being taken to increase recovery from existing fields.Of all the oil discovered so far, it is assumed that recovery of only 35% above the average.
Restoring some of these vast oil resources requires reconstruction of the geological reservoir, a kind of very detailed and little exploration.The reconstructions and models have allowed additional recovery of oil which naturally move into the reservoir.If the remaining oil is immobile because it is too thick, or because he is locked up in very small pores or held by capillary forces, have techniques that are used by petroleum geologists and petroleum engineers to make the oil to move.
