Invizion Evaluation service provides E&P operators an increased level of well integrity assurance by enhancing cement evaluation techniques<\/p>\n
Schlumberger has announced the release of Invizion Evaluation well integrity service, which helps operators evaluate zonal isolation by using integrated drilling, cementing and well logging data.<\/p>\n
\u201cOne 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,\u201d said Amerino Gatti, president, Well Services, Schlumberger.<\/p>\n
\u201cThe Invizion Evaluation service combines all available data from open hole, cementing placement, and acoustic logs for cement evaluation in an integrated workflow. This service supports customer decision making during the well construction and completion phases to help ensure a robust cement barrier.\u201d<\/p>\n
The Invizion Evaluation service uses real-time and post-job data to help identify zonal isolation issues that could impact well integrity. To perform well, pad or field analysis, petrotechnical experts can evaluate drilling surface parameters, formation rock properties, cement barrier placement, and cased hole cement evaluation logs.<\/p>\n
Field tested in a wide range of field locations, including offshore environments in the Gulf of Mexico and Alaska, unconventional wells in Colorado and the Eagle Ford Shale, the Invizion Evaluation service enabled customers to confirm that cement placement was achieved as planned. The service also allowed them to identify zonal isolation issues, understand the reasons the issues existed in the short and long term, and minimize the potential impact on well integrity.<\/p>\n
In Alaska, the Invizion Evaluation service\u2019s integrated workflow was used to help in job planning, and the Isolation Scanner* cement evaluation service was used to successfully save more than 15 hours in waiting-on-cement and operational costs.<\/p>\n
These services enabled the well to be logged 27 hours after the cement job instead of the typical 42 to 72 hours, helped the customer determine the quality of the cement bond, and confirmed that the cement had set.<\/p>\n","protected":false},"excerpt":{"rendered":"
