In 2010:
Encana’s drilling rigs to run entirely on natural gas. After successfully testing the LNG storage and vaporization system the units were readied for operation in the Haynesville Shale Play covering vast amounts of Northern Louisiana. The design of the system was a successful collaboration between Prometheus, Ensign and Encana. The project enabled Encana to realize an estimated $1,000 per day fuel savings versus a drilling rig burning diesel, while also reducing NOx and PM emissions by as much as 25%.

There will be even more savings when manufacturers produce equipment and engines that run on LNG, rather than users having to take a diesel engine and apply a separately purchased conversion kit.
Wait wait wait, this is confusing! This article seems to imply that if we drill more, it drives prices down? But that can’t be because Obama said that drilling for more oil wouldn’t drive oil prices down!

I have enjoyed several interviews of Boone Pickens by Cavuto.
Pickens strongly pushes LNG for fueling , especially of our big rig fleet. He says that if the big rigs were converted, the pressure on supply would evaporate and prices would come down.
He is a plain and outspoken man who seems to tell it like it is. One winders if he is not involved in the transition noted. It would be application of using the thoughts at home before pressing others to make the change.
