The effective exploration area is 5.63×10~4km~2 with the total resource volume being 10000×10~8m~3. This paper focuses on Quaternary natural gas exploration history, current biological gas resources volume, biological gas exploration potential analysis and biological gas exploration target, stressing that rich resource conditions, enormous exploration area and low exploration degree hold the key to success of Quaternary biological gas exploration.
The founding of giant oil-gas fields in the craton basin of West China shows that the Ordovician of Tazhong area in Tarim Basin is the major exploration target for reef type of oilfields,the Cambrian oils beneath the salt-rocks and in the good dolomite reservoirs are also expected to be found.
The next exploration target in the study area is predicted,i. e. the channel sandbody in which high-permeable quartz sandstone is developed in the Member 2 of Shanxi Formation in the Yulin River sedimentary area,which is characterized by the Yulin Gasfield.
The P_1q2 (second member of Qixia Formation, Lower Permian) saccharoidal dolostone reservoir is an important exploration target zone in the buried fault front structural belt of the nappe structural belt in the north section of Longmen Mountains.
The main exploration target is focusing on the stratum of Cretaceous and Jurassic, the eastern depressions is the most promising area for exploration for its favorable condition of hydrocarbon source rock and completed traps.
We report on an objective methodology, referred to as intrinsic sample methodology, for the delineation of exploration target areas or resource areas for assessment.
The lognormal and Pareto distributions have been used to model exploration target sizes.
Following this mission, a "Mineral exploration Project" was created by the Haitian Government with the cooperation of UNDP, and an area of 9000 km2 was selected, based on structural, lithological, and metallogenetic reasons, as an exploration target.
In general, the calc-silicate alteration is restricted to the immediate hanging wall and zones lateral to the deposits and does not represent a regionally extensive exploration target.
They also increase the size of the exploration target.
