The fractal used in analysis of well test data has provided a new tool of reservoir description, which makes it easy to simulate complex reservoir by numerical simulator; fractal can be used to solved some difficult questions in transient pressure analysis; when used to describe fracture and pore it can improve the technique of matrix acidizing and hydraulic fracturing; more information about fingering may be revealed by using fractal to describe multiphase flow. In brief, the development of the basic ...
