USING DYNAMIC UNDERBALANCE TO INCREASE WELL PRODUCTIVITY

摘要

Disclosed are systems and methods that use dynamic underbalancing to increase fluid flow within a wellbore. A disclosed underbalance pressure generator device includes a housing having a first end and a second end and defining a piston chamber that extends between the first and second ends, a piston movably arranged within the piston chamber, one or more influx ports defined in the housing at or near the second end and configured to enable fluid communication between the piston chamber and an exterior of the housing, and a locking mechanism arranged at or near the second end and capable of securing the piston at or near the second end.
