Bathymetric mapping is the first step in any underwater and sea bed investigation, especially for petroleum exploration. In most we face with a complex of sand and gravel covering the bottom of the sea. Differentiate these two type of seafloor covering material is the case of many research in offshore exploration. In this article We investigated a practical case history to define and show the differences of sand and gravel in their images. The images were obtained by the Yellow-Fin side scan sonar instrument and p...

Defining the mineral potential of the sea floor could be handled by different methods, but the prerequisites for each methods is to clear the conditions of precipitation environment such as physico – chemical conditions and also it depends on the type of precipitant. The appearance of any mineral in the sea floor strongly depends on the aqueous environment and the physical prosperities of the mineral. In this article, first of all, I considered the physiographic regions of the sea floor in entire the world, an a...

In this article I considered the design of a computer simulation model that approximates the exploration of a petroleum basin when exploration is conducted sequentially and according to geological hypothesis with costs and performance characteristics typical of an exploration firm. These features lead naturally to a model design in which a state of nature is created. The exploration firm initially has no knowledge of this state, only of hypothesis. In this model also, exploration decision are made according to pri...
