Bottom Hole Pressure Analysis Field Examples

Bottom hole pressures have been measured for many years in the oil industry, primarily for use in productivity and future production predictions. More recently, it has become apparent to petroleum engineers that the pressure transients measured during build-up or draw-down tests contain much quantitative information about the well and the reservoir. Each year more techniques for analysis of these pressure transients become available in the literature, giving the petroleum engineer more opportunities to make money for his company through application of these techniques. This paper presents briefly the theory of some of these techniques and will explain their use by means of field examples.
