One last item is monitoring press releases to see what the drilling companies are doing - here's a snippet from PDS which suggests a recovering market:
Kevin Neveu, Precision's President and Chief Executive Officer stated, "Recent actions to stabilize and improve commodity prices appear to be well received by our customers. We are seeing signs of strengthening demand for our services for the upcoming Canadian winter drilling season and improving demand in U.S. regions where we operate. Since our third quarter earnings release in October, we have added three rigs years to our 2017 contract backlog and now have an average of 45 rigs under contract for 2017. With over 110 drilling rigs currently running in North America, we are experiencing customer demand greater than the prior year for the first time in over two years and are currently enjoying our historically strongest North American market share."
