Considering the rig count in the US has been cut by 75%, which means less drilling, which means less new production for companies such as SDOC I would say OPEC flooding the market has everything to do with the drop in PPS. If a company can't profit due to no demand in the US markets of course companies debt is going to grow and they will be put in a financial bind.
For example my companies profit has dropped 60%, and we have had to cut half our employees to keep the doors open. When oil was 100$ a barrel us and every US based company was growing and profiting.
What you claim makes zero sense, the market and companies profit go hand and hand.
