Abstract: Based on measurements that are obtained from a well test, a pressure in the well is modeled as a function of at least a skin effect factor that varies with time. The results of the modeling may be used to estimate at least one well parameter, such as a formation parameter and/or a well pressure, as examples.

Abstract: A technique that is usable with a well includes communicating fluid from the well into a downhole chamber in connection with a well testing operation. The technique includes monitoring a downhole parameter that is responsive to the communication to determine when to close the chamber.
