Publisher Summary The primary objective of pressure transient formation and well testing is to obtain the productivity of a well and properties of the formation from downhole and/or surface pressure and flow-rate measurements. The formation and reservoir information obtained from pressure transient measurements are essential because they reflect the in situ dynamic properties of the reservoir under realistic production conditions. When pressure transient test data are incorporated with geoscience data such as geophysical, geological, core, log, etc., it considerably improves reservoir characterization. Particularly, when long-term production data are not available for undeveloped reservoirs, it is necessary to complement the volumetric estimate of oil or gas in-place with long-duration well tests to estimate well productivity and reservoir size before the optimization of the field development.
