For optimizing well production, intervals are selected along a deviated wellbore, and a well test and treatment string is deployed in the wellbore. Each interval is then isolated to enable performance of desired testing. The test data obtained is evaluated to determine an appropriate remedial action which is then implemented via the well test and treatment string. The system and method enable the testing and treatment of a plurality of intervals along a horizontal well during the same run downhole.

System and method for optimizing production in a well

The present invention provides for a valve in a tubing string that allows the tubing string to fill with well fluids as the string is assembled and lowered into a well bore, but can be used to check pressure integrity of the tubing string during various stages of the assembly.
