Hi.

Hope some of you experts can help a layman out.

I have been reading up on some of the bigger oilfields in the world, (Ghawar, Cantarell, Burgan, that one in China, etc.) one thing that was a little puzzling to me is the mention of watercut percentages.

I understand that Ghawar is now at around 55% watercut?

Does that mean that 55% of the reservoir is now water? I am slowly learning about the geology and physics of oil fields. But this has me puzzled, because a lot of people claim that the watercuts at Ghawar are indicative of it's peak. But some oilfields, namely Prudhoe Bay, have very high watercuts. It's very confusing for the layperson to sort out.

Any geologist types, or actual oil workers with a perspective to help a guy out? Thanks!

Watercut is the percentage of produced fluids that is water. Thus, 55% of the fluids that is produced at Ghawar is water and the rest is mostly oil.
