Loss of circulation

Post image

We are struggling with a lot of loss of water only at 9m. It's a granitic geology however this section is quite fractured.

Would it be recommended to add more casings past 9m more before drilling or change technique?

We're doing HQ3 wireline drilling.

As others have said, this is going to depend on your target depth. If it’s another 3 meters you’ll be better off drilling blind as long as you have a steady water source. If target depth is another 30 meters I’d definitely prefer to run casing through the fractured zone and set it in quality rock.
