Item 2.01 Completion of Acquisition or Disposition.

As previously disclosed, PDC 2005-B Limited Partnership, a West Virginia limited partnership (the “ Partnership”) entered into an Agreement and Plan of Merger, dated as of November 16, 2010 (the “ Merger Agreement”), by and among the Partnership, Petroleum Development Corporation, a Nevada corporation and general partner of the Partnership (“ PDC”), and DP 2004 Merger Sub, LLC, a Delaware limited liability company and wholly-owned subsidiary of PDC (the ” Merger Sub”) that was approved by the Partnership’s limited partners other than PDC and its affiliates (the “ Investors”) at a special meeting held on June 15, 2011. On June 27, 2011, pursuant to the terms of the Merger Agreement and in accordance with the West Virginia Uniform Limited Partnership Act and the Delaware Limited Liability Company Act, the Partnership merged with and into the Merger Sub, with the Merger Sub continuing as the surviving company (such transaction, the “ Merger”). As of the effective time of the Merger, all of the Partnership’s outstanding limited partnership units held by Investors (other than limited partnership units held by Investors who properly exercise appraisal rights under West Virginia law) were automatically converted into the right to receive cash in an amount equal to $6,544 per limited partnership unit, plus the sum of the amounts withheld from per unit cash distributions by the partnership from October 1, 2010 through February 28, 2011 for the partnership’s well refracturing plan, less the sum of the per unit cash distributions made after February 28, 2011 and before the closing date of the Merger (proportionally adjusted for partial limited partnership units) and the separate existence of the Partnership ceased. As a result of the Merger, the Partnership became eligible for termination of registration under the Exchange Act. Accordingly, the Partnership expects to deregister its shares under the Securities Exchange Act of 1934, as amended (the “ Exchange Act”) and suspend the Partnership’s reporting obligations under the Exchange Act.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the Merger Agreement. A copy of the Merger Agreement was attached as Exhibit 2.1 to the Partnership’s Current Report on Form 8-K filed with the Securities and Exchange Commission on November 22, 2010.

Item 5.01 Change in Control of Registrant.

The information disclosed in Item 2.01 is hereby incorporated by reference. The total cash merger consideration paid by PDC for the limited partnership units of the Partnership (excluding those limited partnership units exercising dissenters’ rights and per unit cash distributions made to Investors after February 28, 2011 and before the Merger closed) was approximately $12.6 million, which PDC funded from borrowings under its revolving credit facility and cash on hand.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Certain Officers; Compensatory Agreements of Certain Officers.

Barton R. Brockman, Jr., President, Gysle R. Shellum, Vice President and Treasurer, and Dan Amidon, Vice President and Secretary, each ceased to serve as officers of the Partnership effective upon consummation of the Merger.
