Best Practices for Cement Squeeze of a Casing Leak

[Basic Engineer via Geology]

We are putting shut-in gas wells back into production to take advantage of the high prices. Of course, we are discovering casing leaks in a few of the wells.

Does anyone have a good "recipe" for a typical cement squeeze of a casing leak? Any discussion of the reasons that a particular procedure is a best practice would be greatly appreciated.

Examples are the optimum spacing of the bridge plug and of the packer relative to the squeeze interval. The correct squeeze operations when things are going smoothly, versus when the well is being uncooperative. The best way to clean out the tubing after the job (since tubulars are getting so expensive) etc. Any other practices that you can think of that are typically handled poorly, or when a mistake is particularly difficult to remedy.

All of the consulting completion engineers we usually utilize are booked with large companies. Much of the work will fall to me (a geologist), so I am trying to increase my education level on this topic. I have done our simple well interventions for many years, but the company has always farmed out the more complicated work to consultants.

Any advice or feedback would be greatly appreciated. There is literally no step so simple that it is beneath discussion.

Thanks!
