Counsel then stated:
Mr. Morris, the next statement by the witness (Harrington) was:
"By picking out where they want to put these injection wells,
(the ETSWDC)--can move oil anywhere in East Texas, and on
some leases, some people, and in the center of the field, have
suffered horribly by the salt water injection practice of putting
water into the oil formation and pushing the oil ahead and over
to the east side of the field. " Is that correct?
A. That is not correct,
Q. What is correct?
A. I think the gentlemen just doesn't understand the mechanics of
the East Texas reservoir... Now, this East Texas Field is not
a lake of oil underneath the ground. It is a consolidated sand,
and the oil is contained within the porous face of the sand, which
is an average of 25 per cent porosity... Now water is in this
formation; trillions of barrels of water, and the water is salted.
It has about the salinity of the water in the Gulf of Mexico...
65 per cent of the field was originally underlain by water.
. the first thing you have to do is get below this water contact
before the commission will even talk to you about locating a
well there. Then after you get below that point, you have to
find one of these shale breaks in here that is below the 3320
foot level, and set your casing down below that shale break.
Now one of the reasons for putting the injection wells back out
there, is that we have got a greater sand section into which to
inject the water, and can inject it easier. But back to this well.
If water is put into that point, beneath this shale break which is
a prerequisite, now, remember, that water would diffuse itself
out, the pressure would be diffused in such a manner, as using
the illustration given by Mr. Payne, like the old lady throwing the
bucket of water in the lake. That's what it amounts to. You
would be putting b4ck here such a relatively insignificant amount
of water compared to the amount of water that is already there,
it would be like spitting in the ocean... Merely putting the fluid down
here, the fluid itself does not have to travel from this point over to
here in order to transmit its pressure. As indicated by a pipeline
a mile long, you fill it with water, and you shut the valves at one
end, and when you pump oil at the other end, the pressure in that
line is going to increase, and yet you have taken no fluid out the
other end of the line. That^s just the mechanics of transmission
of pressure. One molecule transmits it to the other, and there is
actually no movement of the fluid. So I can't see if you would put
the water at Point C indicated, that it could possibly have any adverse
effect on A and B. Now the natural forces are working.
Here’s what’s next.
