METHOD 'OF TUBING AND PACKING ARTESIAN AND OIL.. WELLS.

SPECIFICATION forming part of Letters Patent No. 313,915, dated March 17, 1885.

(No model.)

To @ZZ whom it may concern Be it known that I, JOHN BoLE, a citizen of the United States of America, residing at Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Method of Tubing and Packing Artesian and Oil Vells, of which the followingis a specification, reference being had therein to the accompanying drawings.

My invention consists of the process of excluding salt-water, fresh water, mud-veins, gravel-beds, quicksands, or other substances from oil, gas, or Artesian wells by means of a tube or pipe lowered into the well to the point of inlet of the water or other substance, and when thus in position expanding the pipe or tube into or against the walls of the well at points above and below the place of inlet of the water or other substance, thus effectually eXcluding the foreign or obnoxious substance from the well. The tube or pipe is of length sufficient to cover the place of inlet of the substance necessary to be excluded, and to allow of the necessary points of expansion. The requisite length of tubing or pipe is ascertained by the well-known method of measurement now in use by persons skilled in the art of drilling wells. l

Heretofore it has been deemed necessary to 4use a continuous line of casing :from the surface or derrick-loorto a point below the place of inlet of the water or other foreign substance, in many cases requiring aline of casing twelve hundred to fteen hundred feet in length,thus involving a great expenditure of time, money, andlabor, much of which my invention is designed to obviate. rlhe usual mode of drilling oil or gas wells is to first drill a hole of sufficient depth and diameter to allow the surface water to be excluded. This is done by means of casing of the standard size-five and fiveeighths inches inside diameterwhich is insuspended, the casing withdrawn,| and the hole below the surface casing is enlarged or reamed out to the size of the outside diameter of the casing,and a line of casing inserted, reaching from the bottom of the well to the surface orderrick-iioor, and thedrilling is resumed through the interior of the casing, as before. If in the further progress of the work other veins of foreign substance are found which interfere with the production of the oil or gas, the operation of inserting more casing must be repeated7 thus adding double to the cost of drilling beside the cost of casing.

I will now proceed to describe my invention, so that others skilled in the art to which it appertains may apply the same.

Figure l is a longitudinal central section of the devices embodied in my invention, showing the portions of the parts within the tube when the whole is in readiness for lowering into the well. Fig. 2 is a cross-section of Fig. l at the points a c, showing a sectional disk for expanding the tube or casing. Fig. 3 isa longitudinal central section of the same device,in which,by means of a series of sectional disks, both ends of the tube or casing can be expanded at one operation.

In the drawings, B indicates the stem or mandrel provided with. the usual means of attachment to the jars. The mandrel B is usually made round in its working parts. At its lower end, from points B to B2, it is turned taper.

C designates the body of the'holder of my improved devices, which holder isI provided with lower iianges, F, and upper flanges, F', having threaded holes to receive the bolts E, to secure in place friction'disks or rings D D', of rubber or any other elastic material,and the collar H. The upper ring, D', is constructed and arranged to extend outward sufficiently to bear against the walls of the well for holding the devices in place in the well. The ring D is constructed and arranged to bear against the inner surface of the casing L to hold it in place while being lowered into the well. When required,friction lugs or eccentrics G may be used in connection with and for the purpose of aiding the ring D in holding the casing in place. rlhese eccentrics are pivoted in recesses in the lower portion of the body C, and are constructed and arranged to be forced outward IOO by the enlarged portion of the mandrel against theinner surface of the casing L, as seen in Fig. 3 of the drawings. The collar His made the samev diameter as the outer diameter of the casing, and is arranged, as shown, to bear upon the ends of the casing to prevent it from becoming displaced in being lowered into the Welland to force it down the well should it meet with any obstruction. I is the disk, which is let into the-body C at recess K K. When the mandrel B is resting on the collar or top of body C at b b ando c,the disks I are pushed back into their place against the small or straight part of mandrel B. A tube or pipe of the required length and diameter is then adjusted to its place, and it is ready for lowering intoy the well, as above shown in Figs. l and 3. When the tube or casing is opposite the point of inlet of the water or other substance, the mandrel is drawn or jarred up,the frictional rings D D holding the devices and the casing in place. The inclined portion of the mandrel B is thus forced against the sectional disks I, causing them to expand .outward against the tube orl casing, and in turn forcing the casing solidly into the wall of the Well, and when the mandrel is jarred through and past recess Kthe tool can be withdrawn.

L L in Fig. 1 represent the tube or casing ready to be lowered into the well. The curved dotted lines at M M M M in Fig. 3 represent the tube or casing when expanded into or against the Walls of the well. The feathered lines O O O O in Fig. 3 indicate the wallspof the well with the tube or casing lowered into place and expanded.

Having thus described the nature and advantages of my invention, what I claim, and desire to secure by Letters Patent, is

The process of excluding water,mud,gravel, quicksand, or other objectionable substances from oil-wells, gas-wells, ,or Artesian wells by lowering a pipe or tube forming well-casing to the requiredl position in the well and then expanding the wallsof the casing int-o the walls of the well at thepoints and in the manner required to exclude the objectionable .substances from the well, substantially as and for the purposes set forth. l

In testimony whereof I affix my siguature'in presence of two witnesses.

. JOHN ISOLE.
