Case Study: a leading operating company achieves NORSOK D-010 cement bond verification with SLB PowerFlex annular barrier evaluation

Cement Bond Quality Evaluated in 95/8-in Casing with Highly Attenuative Heavy Mud Norway

SLB worked with a leading operating company offshore Norway that needed to evaluate cement bond quality behind 95/8-in casing in highly attenuative heavy oil-base mud. Conventional ultrasonic logging struggled in this environment because the signal was severely dampened, making well integrity assessment difficult and costly to perform with fluid changes.

SLB deployed its PowerFlex annular barrier evaluation service to measure cement bond quality in the heavy mud environment, including full azimuthal resolution and an SLG map. The solution delivered superior-quality data and quantified results that met the NORSOK D-010 well integrity standard, with a 2-hour turnaround from acquisition to wellsite answers.
