per year New crude wells drilled
on the flank OF the South Area
show bottom-hole pressures OF
about 1900 pounds.
Decline in production Of the
crude wells has been negligible, due
perhaps to several reasons. Crude
production is recent, curtailment
has been in effect and acidization
may have some bearing.
PAST PRODUCTION
/ The total limestone production
of the field, from 1922 to 1887,
has been about sixteen million bar
rels of naptha and crude, mostly.
naptha. Before 1929 records were
not kept accurately.
PRESENT PRODUCTION
The present crude production,
under curtailment, has averaged
100000 barrels per month for 1898,
with a total of 1857 900 barrels
produced in 1887. The month OF
March. 1898, showed 644, ,066 bar
rels produced, against 1925 for
March, 1887. Government figures
released May 18th showed an aver
age daily production OF 33,190 bar
res from forty-five wells or 73S
barrels per day apiece, under cur
tailment.
FIELD ACTIVITY
On May 21st, there we're said to
+ be forty-seven wells producing
crude, thirty-nine drilling, four to
resume drilling, nine preparing to
spud in and locations made for six
others. Since that time there have
been north and west extensions
Through completion of wells in new
areas.
Fifteen of the drilling wells are
below 5000 feet, with nine listed
for immediate completion. Several
of these nine will extend or dis
prove areas to the north, south
and west of present production.
NAPTHA WELLS
There are also said to be about
seventy-five naptha wells capable
of producing. but of which some
forty are shut in, part of them
permanently and some only at times
/ These latter are mostly owned by
the Royalite, which operates an abb
sorption plant in the field.
4 CURTAIINIENT
Curtailment at present is effect
+ ed by the pipeline companies and
stands at 3O% of each wells po-
tential. Potentials are arrived at
through eleven day tests made by
/ the Government. For ten days
the we'll is produced at its fixed or
/ an estimated allowable, then for
! itwenty-four hours is allowed to run
/ entirely open. Two-thirds of the
eleventh days production is then
set as the wells potential.
CRUDE PRICES
The price of crude in the field
/ is now S1.20 for oil of 43 degrees
Baume, with &c additional for each
| degree above 43.
ACIDIZATION
Acidizing is general for both old
and new wells and gets good results.
After acidizing, the wells are re-
tested and new potentials fixed.
FIELD CAPACITY
The Alberta Provincial Depart
ment OF Lands & Mines. Petroleum
& Natural Gas Division, has esti-
mated the reservoir capacity of the
crude oil area of Turner Valley
! to be 100000 barrels per acre with
an oil content of 1000 barrels per
I
acre. Ultimate recovery is set at
3O%. with probable improvement
under present production methods
. to 5O96, or an estimated $4,000 to
$4,000 barrels of recoverable oil
per acre. Gas-Oil ratio is a thou
sand cubic feet per barrel of oil.
Gas-Naptha ratio is $4,000 cubic
feet per barrel of naptha.
NAPTHA PRODUCTION
The original naptha content is
estimated to have been As million
barrels, of which approximately six
teen million barrels have been pro-
duced. Perhaps two million addi-
tional barrels of naptha will be
produced, which will make an ulti-
mate naptha production of 1900
barrels per acre with naptha re-
covery factor of 40%.
PIPELINES
There are three pipelines in Tur-
ner Valley delivering to two re-
fineries. In four months of 1898
they handled total of 1,543.451
barrels. In 1887, they handled a
total for the year of 2,S63,74S bar
rels The two refineries are I'M
periaI and British-A American 1t has
been announced that British-Ameri-
can is now planning a new million
dollar refinery to have capacity
OF 5000 barrels daily. The loca-
tion has not been disclosed.

small leases in proven or semi
