ENI have drilled the extra metres to find the gas water contact. And in the process found a large transition zone and the same thing happened at B1 as MEO never found the GWC either.
So what's gas water contact. the experts say its....
A bounding surface in a reservoir above which predominantly gas occurs and below which predominantly water occurs. Gas and water are somewhat miscible, so the contact between gas and water is not necessarily sharp and there is typically a transition zone between 100% gas and 100% water in reservoirs. Note the word miscible,
meaning or Pertaining to a condition in which two or more fluids can mix in all proportions and form a single homogeneous phase.
So this transition zone is very much gas charged probably due to many factors including very porous formation in the zone.
If oil is present it will be found in between the gas and the water.
formation fluid
Any fluid that occurs in the pores of a rock. Strata containing different fluids, such as various saturations of oil, gas and water, may be encountered in the process of drilling an oil or gas well. Fluids found in the target reservoir formation are referred to as reservoir fluids.
So report no7 talks about fluid phase uncertainty or uncertainty's regarding fluid content,
I think this is what they are looking for so it could be very tricky working out production test in this area.
We don't know but the same thing could have been Encounted at ENIs last ES drill?
And ill add that its only the very bottom of the heron formation in this well that fluid phase uncertainty is about.
And all the better if heaps of gas or oil in fluid area.
My thinking only and ill stick with it at this stage.
Best of luck meomites.
