Stage color leakage

Dear Forum members

 

We have a hole in the stage color in 9-5/8” casing and failed to pressure test the same. The casing is set at 4560m and the color is at 1960m.

For remedial job, we plan to squeeze cement across the color. Due to limited market in Ukraine, we do not have bridge plugs nor do we have cement retainers of this size or any other casing patches in country. Mobilizing any of them will take weeks.

Hence, we think to squeeze above the heavy pill. What are your thoughts and best practices to achieve success from the first time?

For information prior to temperature log we have pumped 11m3 of fluid into the hole and returned 1.5 m3. Apparently, we fracture the previous casing shoe at 2200m.

 

Appreciate your help!
