COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS As described in the Current Report on Form 8-K dated December 19, 2006, the Geodyne Institutional/Pension Energy Income Limited Partnership P-3 and Geodyne Institutional/Pension Energy Income Limited Partnership P-4 (the "Partnerships") sold their interests in a number of producing properties to independent third parties at The Oil and Gas Asset Clearinghouse auction in Houston, Texas on December 13, 2006. The Bilbrey N. Fed 7 #1 well failed to attain the minimum bid set forth at auction, but was sold to the high bidder, Raya Energy Corp., on December 22, 2006 following additional negotiations. The P-3 Partnership owned an interest in this well. The combined net proceeds from the December 13, 2006 auction and the sale of the P-3 Partnership's interest in the Bilbrey N. Fed. 7 #1 well are shown below: Reserves Number Sold as Reserve of Location Number of 12/31/05 Value Wells of of Oil Gas Sold Net P/ship Sold Properties Purchasers (Bbls) (Mcf) 12/31/05 Proceeds - ------ ------- ------------- ---------- ------ ------- -------- -------- P-3 30 North Dakota, 16 2,108 240,160 $730,716 $537,366 New Mexico, and Oklahoma P-4 5 New Mexico 3 580 64,040 246,033 239,927 The transactions are subject to standard auction closing conditions. The proceeds from the sales, less any additional transaction costs, will be included in the February 15, 2007 cash distributions paid by the Partnerships. This sale was part of the General Partner's plan (previously disclosed in the Partnerships' December 31, 2005 Annual Report on Form 10-K) to sell an increased amount of the Partnerships' properties as a result of the generally favorable current environment for oil and gas dispositions. It is anticipated that additional properties will be sold at auction in February 2007. The sale of these properties will impact the continuing future operations of the Partnerships. Future production, costs and cash flow will be reduced as properties are sold. As of the date of this Current Report on Form 8-K, management cannot predict the extent of such reduction. -2- ITEM 9.01.
