nate boring and coating or casing by form-
ing the casing as needed within the well,
until the oil sand is reached and the flow of
the well is assured.
5 What is claimed is:
1. The method of lining the walls of the
bores of deep wells, which walls are of
crumbly nature, which consists in spreading
a lining material over the walls, while such
10 material is subjected to the action of heat,
and. withdrawing the heat while the lining
material hardens.
2. The method of lining deep wells, which
consists in applying to and localizing on the
15 walls of the bore of the well a lining material
capable of responding to the action of heat,
with the thickness of the lining determined
by the clearance between a movable core and
the walls of the bore, with the core inclosing
20 a source of radiant heat.
3. The method of producing and lining
deep wells, which consists ii first producing
a bore of determined depth, with the walls
of the bore sustained by air pressure, then
25 producing a smooth layer of material on the
walls of the bore over a localized area there-
of by a suitable core, producing heat within
the core of an intensity to affect material
constituting the lining of the walls and ulti-
30 mately allowing the lining to harden.
4. The method of producing lined deep
wells, which consists in first forming a bore
to determined depth, then introducing a core
into the bore with the core having means forgenerating heat therein of an intensity to 35
soften lining material between the core and
the walls of the bore, moving the core in the
bore to spread the lining material, and per-
mitting the solidfication of the lining mate-
rial into a self sustaining layer capable of 40
sealing the bore against leakage and cavings
thereinto.
5. The method of lining the bores of deep
wells, which consists in introducing a core
into the well bore in loosely fitting relation 45
thereto, introducing sulfur between the core
and the walls of the bore and softening the
sulfur by heat generated in the core, and
moving the core lengthwise of the bore to
spread the softened sulfur over the walls of 50
the bore.
6. The method of lining deep wells, which
consists in providing a core loosely fitting
the well bore and movable therealong, in-
troducing a mixture of sulfur and lime into 55
the space between the core and the wall of
the bore, heating the mixture by the applica-
tion of heat thereto produced within the core
and conducted through the walls of the lat-
ter to the mixture, and moving the core 60
lengthwise of the bore to spread the heated
and softened mixture over the walls of the
bore for the production of a lining when the
mixture has cooled.
In testimony that I claim the foregoing as 65
my own, I have hereto affixed my signature.
