Influence of the Terrigenous Reservoir Facial Heterogeneity on Processes of Oil and Gas Fields Development

In the article new technique for evaluating porosity-permeability properties of the clastic reservoir matrix are suggested. This technique bases on four types of porosity-permeability heterogeneity. Relations between allocated types and conditions of the formation forming process are described. Influence of these types on oil and gas fields development processes is showed. Aspects of the formation exploitation characteristics based on using of potential abilities of the allocated types are described.
