Hello im trying to work out ii from this question are you abe to help?

The USA produces both oil and natural gas. It has a ready home market for its oil and burns a proportion of its natural gas production in raising steam for enhanced oil recovery (EOR) to boost its oil production.

i. - The energy content of high-pressure steam can be assumed to be 2.7 GJ tonne^-1. If the steam is raised in boilers that have a thermal efficiency of 82%, calculate how many GJ of gas are required to produce a tonne of steam.

my answer - 2.7 GJ per tonne / 0.82 = 3.29 GJ of gas required

Q- ii -In 2023, the USA produced an average of 2910 million cubic metres of natural gas per day. If it used 1.7% of this to raise steam for EOR, calculate how many thousand tonnes of steam it produced per day. The calorific value of natural gas is 39 MJ m^-3.
