I just took a look at the Bankers Q4 Operations update and Bankers indicated that they loaned a drilling rig to another Albanian oil company for an 8 week period. I am not aware of any other Albanian oil company that would be drilling a well aside from Stream.
If Bankers did loan the drilling rig to Stream I suspect that Stream would use this Rig to drill into the Delvina formation. Also, it would make sense that the offtake agreement for any gas would go to Bankers. Bankers was unsuccessful in finding gas in their exploratory block F last year.
Hope all is well,
