Called Invizion Evaluation, the service evaluates drilling surface parameters, formation rock properties, cement barrier placement, and cased hole cement.

“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. This service supports customer decision making during the well construction and completion phases to help ensure a robust cement barrier.”

Announcing the service’s official launch on 28 October, Schlumberger said the service was tested in a range of locations, including the Gulf of Mexico and Alaska, unconventional wells in Colorado and the Eagle Ford Shale.

In one case in Alaska, Invizion and Schlumberger’s Isolation Scanner cement evaluation service saved more than 15 hours in waiting-on-cement and operational costs, the company said.

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.
