Ann: Annual Financial Report 2022, page-23

I just realised the from the last Quarterly:
"At the Jo Mill Field in Texas, flow loop testing from Benchmark Labs indicated very significant successat both removal of paraffin deposition as well as prevention of paraffin deposition when HCD Multi-Flowis fed at a laboratory rate of 1200 PPM (estimated equivalent of ~300 PPM feed rate in the field) showingHCD Multi-Flow is an excellent paraffin inhibitor and paraffin deposition cleaning chemical."

The Jo Mill Field in Texas is owned and run by Chevron. Link: Source

HCD must be in talks with Chevron.
Chevron is also an operator in the Permian Basin.
