The poetic irony!

A flame chart of energy consumption to customer from well-head typically shows an astronomical amount consumed at head in the gas train. It can be a significant sub of the total available energy consumed at the head and in pipeline and shipping, to produce the output which can be sold.

Unfortunately much of it can't be sold or shipped off site and if it isn't used, will be fugitive gas emissions or flared.

Replacing the diesel and other fuels used on-site is good. But it's only part of the story. Running the train would certainly burn a lot of gas, so replacing that would be good.
