COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS As described in the 8-K dated October 17, 2006, the Geodyne Institutional/Pension Energy Income P-1 Limited Partnership and Geodyne Institutional/Pension Energy Income Limited Partnership P-3 (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 October 11, 2006. The J.E. Parker H well failed to attain the minimum bid set forth at auction, but was sold to the high bidder, XTO Energy, Inc., on October 16, 2006 following additional negotiations. The combined net proceeds from the October 11, 2006 auction and the sale of the J.E. Parker H 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-1 40 Texas 15 57,599 60,745 $1,484,123 $3,181,737 P-3 40 Texas 15 72,667 76,543 1,871,480 4,011,219 The transactions are subject to standard auction closing conditions. The proceeds from the sales, less any additional transaction costs, will be included in the November 15, 2006 cash distributions paid by the Partnerships. These sales were 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 December 2006 and 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. FINANCIAL STATEMENTS AND EXHIBITS (B) Pro forma financial information.
