Interesting company. I dont quite understand the low uptake. These oilers have millions in cash. From the past annc, a trial of the product costs 100kish?

there have been multiple trials over a couple of years with no significant uptake. With the price of oil (outside oilers control) squeezing margins, you'd think there would be a push to look at effiences to improve margins( i.e. within control) and gain a competitive advantage. It doesnt make sense that oilers would be reluctant to progress with the HCD trial given the relatively low cost of trialling.

The only other conclusion is that whilst the product works, the return on investment is negligible( except in more specific circumstances).

There may be more going on in the background given director buying, but past history leaves it very high risk.
