"The error in the cement job caused a loss of about 4 to 5 days, but that can be caught up if all goes correct after this. It is important to have a good cement bond between the casing and formation. We have established this bond and there is no risk for the future of the well. Now, with a good cement bond the rest of the borehole which is the gas pay zone can be drilled safely. I have seen this happen before and it is not an issue at all, just takes time to fix and we have done that."
Trillion Energy is focused on natural gas production for Europe and Türkiye with natural gas assets in Türkiye and Bulgaria. The Company is 49% owner of the SASB natural gas field, one of the Black Sea’s first and largest-scale natural gas development projects.
