Land based drilling rig power consumption

[MortenA]

Im doing an emmisions estimate for a proposed salt cavern development. I have been informed that the rig uses approx 8 m3 diesel fuel for power generation/day.

I find that this is approximately 1 MW electric energy - does this sound like a lot for a drilling rig?

Best regards

The few land-based drill rigs I've seen have each had 3 or 4 Caterpillar 3512 diesel engine gensets, at approximately 1500hp per engine. That'd give you a total of 3MW to 4MW electric. Sounds like your rig is a smaller one.

You're probably using a single or a completions rig. Your estimate might be correct.
What I have not figured out yet is why contaminate all that fresh water to 'drill' a salt cavern. I am just hoping it won't be for waste water disposal, is it?

gas storage is the purpose. The water used in my area is usually sea water that is returned as saturated brine to the sea. The sea is full of salt and a little extra does no harm.

Its all about depth and ratings. There's rigs working at 850 m that have 150hp on the hoisting, 300 hp on the pumps, and 25 kw gen sets. There are rigs rated to 5500 m that have 1500 hp on the hoisting apparatus, twin 1400 hp pumps wjich may or may not be online together, and twin gen sets 400 hp or more each. There simply isn't enough information in your post to give a reasonably accurate answer.

I read the question as "is 1MW within reason," and the answer is yes. If the question was "how much power will the drill rig use" then I agree we'd need much more info to be able to guess with any accuracy.
