Now, therefore, the Court finds, concludes and orders as follows:

FINDINGS OF FACT
1. An involuntary petition under Chapter 7 of the Bankruptcy Code was filed against the debtor on March 4, 1983, which was converted to a case under Chapter 11 of the Bankruptcy Code on March 18, 1983.
2. The debtor is in the business of producing and selling natural gas.
3. Prior to the enactment of the Natural Gas Policy Act (NGPA, 15 U.S.C. 3301, et seq.) in 1978, the policy of the Federal Power Commission, the predecessor of the Federal Energy Regulatory Commission (FERC), was to measure the energy content of natural gas according to "wet" conditions for purpose of making adjustments to the gas rates set by the Commission.
*489 4. With the enactment of NGPA, FERC abandoned the wet rule and adopted the "dry" rule, under which the energy content of natural gas is measured at the conditions under which the natural gas is delivered for sale. The change from measurement based under wet conditions to that of measurement under dry conditions was significant because it effectively raised the wellhead prices of natural gas.
5. On August 9, 1983, in Interstate Natural Gas Association of America v. FERC, 716 F.2d 1 (D.C.Cir.1983), the Court found that the dry rule was inconsistent "with the Btu measurement technique implicit in the NGPA" and vacated FERC's use of that rule.
6. In response to the Court's holding in that case, FERC subsequently issued various refund rules and interpretative rules under which producers and sellers of natural gas were to refund claims for Btu measurement overcharges. The debtor, as a producer and seller of natural gas is subject to these refund rules.
7. Order No. 356 entered January 19, 1984, specifically required that maximum lawful prices for gas under NGPA be calculated under the wet condition rule, and the amendments contained in Order 356 were retroactive to December 1, 1978, the effective date of NGPA.
8. On May 3, 1984, FERC issued its rule on refunds (49 CFR 19297, May 7, 1984), requiring producers of natural gas to refund overcharges.
9. Certain producers who sold 10 million Mcf or less of natural gas, such as the debtor, were required to refund overcharges, including interest to the date of payment, by May 3, 1984.
10. FERC followed these rules with various supplemental rules.
11. Louisiana Gas System, Inc. (LGS) purchased gas production from the debtor pursuant to a gas purchase contract dated November 15, 1981.
12. LGS claims it overpaid the debtor for gas products from July 1982 to April 1984, plus interest from July 1982 to September 1984.
13. A total of $3,794.06 is attributable to LGS's pre-petition production and interest through March 4, 1983. Post-petition interest on this amount as of April 30, 1984, is $995.72.
14. The debtor paid LGS $410.93 on May 3, 1985, for that portion of the rebate attributable to production after March 4, 1983, and paid interest from the date of overpayment through April 30, 1985.
15. Tennessee Gas Pipeline (Tennessee) purchased gas production from the debtor pursuant to a gas purchase contract dated January 12, 1979.
16. Tennessee is claiming rebates for overpayments from April 1982 to June 1983, plus interest from April 1982 to September 1984.
17. The portion of Tennessee's demand attributable to pre-petition production and interest through March 4, 1983, is $49,880.94 with post-petition interest on this amount as of April 30, 1985 at $12,979.55.
18. The debtor paid Tennessee $1,763.06 on May 3, 1985, for that portion of the rebate attributable to production after March 4, 1983, and interest from the date of overpayment through April 30, 1985.
19. Northwest Central Pipeline Corporation (Northwest Central) purchased gas production from the debtor pursuant to a gas purchase contract dated May 10, 1979.
20. Northwest Central is claiming rebates for overpayments from December 25, 1981, to August 25, 1983, plus interest from December 25, 1981, to September 30, 1984.
21. The portion of Northwest Central's demand attributable to pre-petition production and interest through March 4, 1983, is $53,931.71 with post-petition interest on this amount as of April 30, 1985, at $14,153.91.
22. The debtor paid Northwest Central $19,917.01 on May 3, 1985, for that portion of the rebate attributable to production after March 4, 1983, and interest from the *490 date of overpayment through April 30, 1985.
23. Mississippi Power and Light Company (Mississippi) purchased gas production from the debtor pursuant to a gas purchase contract dated April 17, 1980.
24. Mississippi is claiming rebates for overpayments from May 1980 to July, 1984, plus interest from May 1980 through December 30, 1984, as set forth in its demand letter of October 2, 1984.
25. The portion of Mississippi's demand attributable to pre-petition production and interest through March 4, 1983, is $70,838.36 with post-petition interest on this amount as of April 30, 1985 at $18,590.93.
26. The debtor paid Mississippi $32,044.82, May 3, 1985, for that portion of the rebate attributable to production after March 4, 1983, and interest from the date of overpayment through April 30, 1985.
27. The facts are undisputed by the parties herein.
28. At the hearing of this matter, the debtor moved to dismiss FERC as a party herein and the motion was granted.

CONCLUSIONS OF LAW
The debtor has paid all Btu refund claims attributable to post-petition production.
The debtor argues that the remaining refunds due are pre-petition debts since such refunds originated out of pre-petition sales of natural gas. As pre-petition debts, these claims would be treated as general unsecured claims.
LGS, Tennessee, Northwest Central and Mississippi, on the other hand, argue that the refunds due on the pre-petition sales of natural gas are post-petition debts since the order requiring the refunds was entered post-petition. These claimants, in effect, argue that the remaining refunds owed by the debtor are entitled to administrative priority status.
As counsel for both the debtor and claimants have advised this Court, there is no legal authority directly on point with the facts herein.
In support of their argument, claimants cite the following cases: In re Hammett, 21 B.R. 923 (Bkcy.E.D.Pa.1982), In re Braniff Airways, Inc., 42 B.R. 443 (Bkcy. N.D.Tex.1984), In re Internal Revenue Service Liabilities and Refunds in Ch. 13 Proceedings, 30 B.R. 811 (D.C.M.D.Tenn. 1983), In re American Motor Home Rentals, Inc., 10 B.R. 53 (Bkcy.W.D.Mo.1981), In re Keene, 42 B.R. 239 (Bkcy.Me.1984).
All of the cases cited by claimants deal with unique set-off situations involving mutuality of obligations. These cases are inapposite herein since there is no question of set-off involved. In fact, none of the claimants has argued a right of set-off. Rather, the claimants seek what amounts to a preferred position in relation to other creditors of the debtor.
The FERC rules and regulations are not concerned with equality of distribution between creditors, but the bankruptcy laws are so concerned.
See: In re Kessler
23 B.R. 722 (Bkcy.S.D.N.Y.1982)
As in In re Kessler, the genesis of the debt herein is based "entirely on pre-petition factors," i.e., the sale of natural gas product. Although the refund order was entered post-petition, the event that created the debt occurred pre-petition. Claimants were overcharged prior to the filing of the debtor's petition, and that is when the debt owed to claimants arose.
See: In re Cott
47 B.R. 487 (Bkcy.D.Ct.1984)
Further, in order to sustain the argument that they are entitled to priority or administrative status, claimants would have to show that they provided a measurable benefit to the debtor's estate.
Section 503, Bankruptcy Code
Section 507, Bankruptcy Code
In re Kessler, supra.
No such benefit has been shown in this case.
There is no reason under the Bankruptcy Code as to why these particular creditors *491 should be given priority status or administrative status in this bankruptcy case.
Section 507, Bankruptcy Code
Section 503, Bankruptcy Code
In re Baldwin-United Corp.
43 B.R. 443 (S.D.Ohio, W.D.1984)
In re Pittston Stevedoring Corp.
40 B.R. 424 (Bkcy.S.D.N.Y.1984)
The debtor's Motion for Summary Judgment is due to be granted. The Motions of Northwest Central Pipeline Corporation and Tennessee Gas Pipeline Company for Summary Judgment are due to be denied.
As to those claimants who did not have notice of the debtor's Chapter 11 case, the bar date for filing claims herein is due to be extended until the 1st day of November, 1985.
The debtor's Motion to Dismiss FERC as a party is due to be granted, and the Motion of FERC to Dismiss Complaint is due to be denied.

ORDER
Now, therefore, it is hereby ORDERED, ADJUDGED and DECREED that the Motion of Marion Corporation, debtor herein, for Summary Judgment be, and it hereby is, GRANTED; and refunds due for overcharges upon the sale of natural gas product by Marion Corporation which sales occurred prior to the filing of the debtor's Chapter 11 petition be, and they hereby are DECLARED pre-petition claims; and it is further
ORDERED that the Motions of Northwest Central Pipeline Company and Tennessee Gas Pipeline Company for Summary Judgment be, and they hereby are, DENIED; and it is further
ORDERED that the debtor's Motion to Dismiss Federal Energy Regulatory Commission as a party be, and it hereby is, GRANTED; and it is further
ORDERED that the Motion of Federal Energy Regulatory Commission to Dismiss Complaint be, and it hereby is, DENIED; and it is further
ORDERED that as to those claimants whose claims arose as a result of entitlement to a refund based upon the purchase of natural gas from the debtor prior to the filing of the petition herein, the bar date for filing claims in this case is hereby extended until the 1st day of November, 1985.
