...-tubing cement evaluation ahead of an online Hydraulic Workover Unit (‘HWU’) campaign, simplifying the execution and giving better planning on running remedial work if needed, such as perforate, wash and cement (‘PWC’). Low-cost, conventional cement bond log (‘CBL’) tools are available in the market...

... is placed above TOC, and the casing is retrieved from the well. There are several challenges associated with cement evaluation in old wells. The well may have gas or gasified fluid in the wellbore, depleted formations making it difficult or impossible to fill the wellbore with liquid prior to cement...

... of unwanted fluid, i.e. water behind casing. The cement evaluation logs performed in the first four wells revealed presence of microannulus response across the same sands in the field. This microannulus occurrence complicated the decision making on perforation intervals. There was a need to prevent...

A new-generation ultrasonic imaging tool was deployed to increase the confidence in cement evaluation...
