CHRONOLOGICAL HISTORY

MIRT, spud.

Drilled to 180' and ran surface casing.

WOC, nippled up and resumed drilling.

Ran DST No. I (misrun) in Muddy Sand.

Drilled to 3809'. Lost 7 drill collars in hole.

This was the cheek that fulfilled the bond requirement for drilling the oil test known as Permit 44660 Benedum 441 Kaiser in Custer County, South Dakota; your obligations in this oil test have been complet*d.

If there is any other way that I can be of help to you, please let we know.

Dear Mr. Benedum,

On March 7, 1973 I inspected the site of the Benedum 01 Kaiser oil test (permit 661) which you drilled in South Dakota last summer. The surface has been leveled and smoothed:sand the dry-hole marker has been erected but it is incorrectly marked. It shows the loc-ation of this well to be in township 3 S., whereas in reality it is in township 4 S.

When this discrepancy has been corrected please let me know so that I may reinspect the site and only then recorarend the release of bond.

Dear Miss Larson:

Re: Paul G. Benedum, Jr. Kaiser Ranch Well #1

Under date of June 19, 1972, we forwarded to you a certified check in the amount of $5,000.00 as a Drilling Bond on the above referred to well. The Oil and Gas Board approved the drilling of this well and issued Permit #661. The well was drilled in as a dry hole on the Ilth of July,1972.

To the best of my knowledge all of the information required has been submitted to Dr. Duncan McGregor, State Geologist. As of the date of this writing we have had no word from either Dr. McGregor or your office as to when we may expect our $5,000.00 Drilling Bond returned to us. Certainly from July of 1972 to March of 1973 should be sufficient time for the Geological Department to notify the State Board that the well has been plugged and abandoned and to authorize release of our Drilling Bond. As I explained to you once before we are small independent operators and the holding of this amount of money from our operations creates a hardship on us.

Anything you can do on our behalf to expedite this matter will be appreciated.

Very truly yours,

Mrs. Alice C. Kaiser ' ■

Hermosa South Dakota 57744

Dear Mrs. Kaiser:

I have been advised that tam Paul G. Benedum, Jr. has obtained a Permit to Drill for Oil and Gas on your land in Section 3

4S , R 10E

Occasionally, owners of land consider converting abandoned oil wells into water wells. Please advise me whether or not you intend to convert the oil well drill hole on your land into a water well if water is en-countered and the drill hole is abandoned as an oil well.

If you are considering making a water well out of the abandoned oil well drill hole, special considerations are necessary to comply with the State's oil and water laws. The abandoned oil hole must be properly plugged and the water well properly constructed. All conversion work will be at your expense. The cost will vary, depending upon the characteristics of the drill hole, but such cost will be in the neighborhood of $5,000 or more. Usually another driller and drill rig will have to be arranged for. This other drill rig and casing and other materials will have to be on hand to take over immediately after the special oil well plugging is completed, because the drill hole cannot be left open for any appreciable length of time without spoiling it. Approval of plans for construction of the water well will be required, and a bond covering proper construction may be required. Also, a water right may be required. All of these arrangements take considerable time to accomplish.

Please advise me immediately if you plan to convert the oil well drill hole into a water well. We both hope that a producing oil well results from the drill hole on your land; however, if not and you are planning on a water well, we must start making arrangements now.

Sincerely,

J. W. Grimes Chief Engineer
