Item 1. Security and Issuer.

        This Amendment No. 2 to Schedule 13D relates to the Common Stock, $.10
par value, (the "Common Stock") of PrimeEnergy Corporation, a Delaware
corporation ("PrimeEnergy"). The principal executive office of PrimeEnergy is
located at One Landmark Square, Stamford, Connecticut 06901.

Item 2. Identity and Background.

        This Amendment No. 2 to Schedule 13D is being filed on behalf of Mr.
Matthias Eckenstein. Mr. Eckenstein, who is a citizen of Switzerland, is an
investor, architect and developer. His business address is Solothurner Strasse
94, 4008 Basel, Switzerland. Mr. Eckenstein is at present a Director of
PrimeEnergy, the issuer of the securities to which this Schedule relates and has
held that position since August, 1989.

        Mr. Eckenstein has not, during the past five years, (a) been convicted
in a criminal proceeding (excluding traffic violations or similar
misdemeanors), or (b) been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final order enjoining
further violations of, or prohibiting or mandating activities subject to,
federal or state securities laws or finding any violation with respect to such
laws.

Item 3. Source and Amount of Funds or Other Consideration.

        The shares of the Common Stock held by Mr. Eckenstein were acquired
utilizing personal funds of Mr. Eckenstein.  An aggregate of 138,460 of the
shares held by him were acquired in payment of an outstanding unsecured note in
the principal amount of $415,380 from an individual, Mr. Charles E. Drimal,
Jr., a Director and President of PrimeEnergy.

        No borrowed funds were used in connection with the purchase or
acquisition of the shares of the Common stock.

Item 4. Purpose of Transaction.

        The shares of the Common Stock held by Mr. Eckenstein were acquired as
an investment. As noted, Mr. Eckenstein is a Director of PrimeEnergy. Although
Mr. Eckenstein may develop other plans or proposals in the future, at present
he has no plans or proposals which relate to or would result in:

        (a)  The acquisition by any person of additional securities of the
issuer, or the disposition of securities of the issuer; (b) an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the issuer or any of its subsidiaries; (c) a sale or transfer of a
material amount of assets of the issuer or of any of its subsidiaries; (d) any
change in the present Board of Directors or management of the issuer, including
any plans or proposals to change the number or term of Directors or to fill any
existing vacancies on the Board; (e) any material change in the present
capitalization or dividend policy of the issuer; (f) any other material change
in the issuer's business or corporate structure, including but not limited to,
if the issuer is a closed-end investment company, any plans or proposals to make
any changes in its investment policy for which a vote is required by Section 13
of the Investment Company Act of 1940; (g) changes in the issuer's charter,
bylaws or instruments corresponding thereto or other actions which may impede
the acquisition of control of the issuer by any person; (h) causing a class of
securities of the issuer to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an inter-dealer quotation system of
a registered national securities association; (i) a class of equity securities
of the issuer becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Act; or (j) any action similar to any of those
enumerated above.

Item 5. Interest in Securities of the Issuer.

        Mr. Eckenstein is the beneficial owner of an aggregate of 252,829 shares
of the Common Stock, all of which are held directly and as to all of which
shares Mr. Eckenstein has sole voting and dispositive power. Because of the
repurchase of shares of the Common Stock by PrimeEnergy in open market and
private transactions from time to time during the period ending March 30, 2001,
decreasing the number of shares of the Common Stock outstanding at that date to
3,886,511, the beneficial ownership by Mr. Eckenstein of the Common Stock has
increased to 6.5% of the outstanding shares at that date.

        There have been no transactions by Mr. Eckenstein in the Common Stock in
the past sixty days.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer.

        There are no contracts, arrangements or understandings of any kind,
legal or otherwise, between Mr. Eckenstein and any person with respect to any
securities of the issuer. As noted, Mr. Eckenstein is a Director of
PrimeEnergy.

Item 7. Material Required to be Filed as Exhibits.

        There are no exhibits filed with this Schedule.

                                   Signature

        After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.

Dated:  April 4, 2001
