What measures should be taken in the event of gas migration during well cementing? 🛢️

The recommended solution is a Cement Anti-Gas Migration and Gas Block Agent. This advanced additive effectively prevents gas migration, ensuring a reliable seal and enhancing the integrity of cement barriers in oil and gas wells.

The cementing program should show the standoff ratio of the casing to make sure the casing is centralized, which leads to good cement bond quality.

The figure below shows the real standoff ratio for 13 3/8" casing with 49 different types of centralizers.

Do you think the ratio meets the requirements?

To calculate the required thickening time for a cement slurry, apply the following equation:

Thickening time = mixing and pumping time + dropping wiper plug time + displacement time + safety time (1–2 hours).
