Refracture treatments have been effectively used for production enhancement for decades. Typical motivations for refracture treatments include: restoring the fracture conductivity to the (possibly) "damaged" proppant pack of the initial fracture treatment; achieving a longer propped fracture by placing a much larger volume of proppant; or simply achieving a more effective proppant pack through the use of vastly improved fracture design procedures1 . This paper describes tiltmeter hydraulic fracture mapping field studies which conclusively document a significant additional motivation for refracture treatments, namely: refracture reorientation. Reorientation of propped refracture treatments allows contact with undepleted reservoir from older existing wellbores, which can restore production to near initial rates.
