Lloydminster on and Gas Field
The only commercial field as yet developed
IN Saskatchewan is the Lloyomtnster field,
which straddles the tnter-provincial boundary
between Alberta and Saskatchewan, approx
mateIy $50 miles north Of the Information

the Lloydminster NO. /, came in with flow
Of 100000 feet per day and is now uth-
lied for the town Of LloydminSter. Subsequent

The last three wells drilled by
the Colony OH and Gas Co., the original
discovery by the Isloydminster OIL and Gas
Co., and Triangle OIL and Gas Co. Is now
drilling a well very close TO the Inter-pro-
vincal boundary.
The structure is a quaquaversal dome,
caused by the intersection Of two folds, the
Ribstone and the Lone Rock anticlines. Gas
Is found In three horizons. the lower two
being the most important. These horizons are
encountered at depths averaging l,4OO, l,7OO
and 1000 feet. The !, 700 foot horizon is at
the contact Of the Upper and Lower Creta-
ceous. and the 1000 foot horizon Is towards
the base of the Lower Cretaceous.
The area covered by the structure is quite
large, though at present wells drilled have
only, far proven up some $4,000 acres.
The pressure In the l,700 foot sand Is 440
pounds per square inch. and the thickness
lower sand is sos pounds and thickness over
SO feet. Estimates as to the gas reserves
In this fold are hazardous to make as the
entire extent Of the reservoir at present has
not been sufficiently delineated by drilling.
but on the basis Of information derived from
wells drilled so far, reserves have been varl-
ously estimated at from 100 to 1872 billion
cubic feet, with the very great probability
that these viii be extended as further drill

carried on in this region for a number OF /
years by various parties and corporations.
