RE:Library sales history Not asking for too much are you? I doubt anyone posting a list of merger rumours would be very helpful? If a merger happens you can pretty much assume PSD will make a lot of money from it unless those companies don't drill in Western Canada. As for the companies who have purchased seismic services recently, the correct answer is "everyone that needs one". Pulse's business is a monopoly business. If you want to drill in Western Canada you have to pay Pulse Seismic a fee for their survey or you can simply use the more expensive hit and miss technique.
