For CGX drilling teamGents,
I have no idea what you are doing right now, but just saying:
Your neighbors from across the border solved the losses below the 11-7/8" (i.e. your 11-3/4") with a cement squeeze using a stinger (if your nozzle sizes allow it, cement through the BHA, it will cost you less to pay for potential MWD damage than for a trip around). This should allow you to bring your losses to an acceptable level while keeping your upper zone with higher pore pressure in check and then run your 9-5/8".
Apologies for sticking my nose into your operations but XMas is around the corner.
Thanks for your attention,
And GLTA for the shareholders,
