Item 8.01         Other Events.

On February 2, 2012, Tri-Valley Corporation (the “Company”) and TVC OPUS 1 Drilling Program, L.P. (“Opus”), of which the Company is the managing partner, each received a subpoena issued by the staff of the Securities and Exchange Commission  (“SEC”) seeking documents and data for the period from January 1, 2002 to the present, relating to their  financial condition, results of operations, transactions, activities, business, and offer and sale of securities of the Company and Opus.  The SEC staff is conducting a non-public fact-finding inquiry into possible violations of the federal securities laws, and this investigation does not represent a conclusion by the staff that there have been any violations of the federal securities laws nor whether the staff would conclude that any enforcement action is appropriate.  The Company is cooperating with the staff's request and is in the process of responding to the subpoena.  The Company has consulted with the independent special committee of Opus partners on this matter.  The Company is unable to predict what action, if any, might be taken in the future by the SEC or its staff as a result of the matters that are the subject of these subpoenas or what impact, if any, the cost of responding to this staff inquiry might have on the Company’s consolidated financial position, results of operations, or cash flows.

The Company’s cooperation with the SEC in its inquiry is consistent with the Company’s decision to address and resolve various legacy issues of the Company and Opus.  The Company continues to evaluate and intends to pursue claims against those responsible for such issues where it is cost-effective to do so.  The Company continues to work cooperatively with the Opus special committee, established by the Company for the purpose of resolving those issues arising from the prior management and operation of Opus and its drilling program activities.  Once finalized, the Opus settlement and restructuring transaction will be put to a vote by the Opus investors in accordance with the Opus partnership agreement.
