The whole process of Petroleum Exploration and Development – Geological Exploration

Geological Exploration means that petroleum explorers use geological knowledge and carry simple tools such as compass and hammer to understand sedimentary strata and structural features by directly observing and studying the bottom layer and rocks exposed on the ground in the field. Collect all geological data in order to identify the favorable zones and distribution patterns of oil and gas generation and accumulation, so as to achieve the purpose of finding oil and gas fields. However, because most of the surface is covered by modern deposits, geological exploration is greatly limited. The process of geological prospecting is indispensable. It greatly reduces the area where geophysical prospecting will be carried out and saves costs.

Ground geological survey method is generally divided into general survey, detailed investigation and detailed measurement of three steps. Survey work is mainly reflected in the “search”, its basic map is called a geological map, which for the detailed survey phase to identify the area and scope of potential oil. Detailed investigation is mainly reflected in “selection”, which further confirms the selection of more powerful oil-bearing structures in promising areas. The fine survey is mainly reflected in “determination”, it selected the structure, through the fine survey to determine the oil-bearing structure, the preparation of accurate structural map for further drilling, its purpose is to find oil and gas fields as soon as possible.
