During the exploration in Taipingzhuang structure

the GeoX software has mainly be applied to make geologic risk analysis

estimation of hydrocarbon resources

and economic evaluation.(1)Through setting valuation on marginal probability

and probabilities of effective reservoir (P

1

)

effective trap(P

2

)

effective source rock and hydrocarbon accumulation (P

3

) and effective preservation(P

4

) in both exploration targets

Yingcheng Formation and Quantou Formation

the finding probabilities in the two reservoir sets have been calculated to be 0.192 and 0.201

respectively.It can then be judged that the exploration in Taipingzhuang structure would be in the category of moderate geologic risk.(2)Giving the 12 parameters

including trap area

reservoir thickness

geometric configuration

effective porosity

trap's fillup efficiency

oil/gas saturation

etc

the resources in place and recoverable resources in the target structure can then be estimated to be 2.91million tons and 0.6 million tons

respectively.It should be of small field with rather low abundance.(3)Lastly

economic evaluation of the exploration target has been made.The geologic reserves in Taipingzhuang structure has now been proved to be 0.76million tons of oil

very similar to the estimating result made with GeoX software.
