Schlumberger announced today the release of Invizion Evaluation* well integrity service, which helps operators evaluate zonal isolation by using integrated drilling, cementing and well logging data. “One key component in achieving zonal isolation is cementing, which can impact productivity, help prevent sustained casing pressure and annular flow, and mitigate loss of well control issues,” said Amerino Gatti, president, Well Services, Schlumberger. “The Invizion Evaluation service combines all available data from open hole, cementing placement, and acoustic logs for cement evaluation in an integrated workflow. The Invizion Evaluation service uses real-time and post-job data to help identify zonal isolation issues that could impact well integrity.
