Estimation of Formation Properties by Analyzing Response to Pressure Changes in a Wellbore

摘要

A system and method for estimating properties of a hydrocarbon-producing formation includes varying the pressure in one or more first wellbores and analyzing the effect of the pressure variations in one or more second wellbores. The analysis may be accomplished by applying the pressure variations at varying timescales to enable the testing of multiple paths through the formation at the same time. The analysis may be used to estimate properties of the formation and a field that includes multiple well sites or potential well sites. The analysis may be used to enhance the operation of one or more of the wells and to identify potential future well sites.

1. A method for estimating the properties of a geological formation near a wellbore, the method comprising:
operating an artificial lift system at a first rate for a first time period to apply a reduced pressure to the wellbore; operating the artificial lift system at a second rate for a second time period; monitoring the change of a fluid level in the wellbore over the second time period to estimate a property of the geological formation.
