As required pursuant to Rule 13d-2(e) under the Securities Exchange Act of 1934,
as amended, (the "Exchange Act") the undersigned, EUGENE M. ISENBERG, hereby
amends and restates his Schedule 13D, as previously amended, with regard to the
common stock, par value $0.001 per share, of NABORS INDUSTRIES LTD. as follows:

ITEM 1. SECURITY AND ISSUER

         The securities to which this Schedule 13D relate are the shares of
common stock, par value $0.001 per share ("Shares"), of Nabors Industries Ltd.,
a Bermuda exempted company ("Nabors") which, for purposes of filings under
Section 13(d) of the Exchange Act, is the deemed successor issuer to Nabors
Industries, Inc., a Delaware corporation. The address of Nabors' principal
executive offices is c/o The Corporate Secretary Limited, White Park House,
White park Road, Bridgetown, Barbados.

ITEM 2. IDENTITY AND BACKGROUND

         Eugene M. Isenberg (the "Registrant") resides at Two North Breakers
Row, Suite #S-25, Palm Beach, Florida 33480. His present principal occupation is
Chairman of the Board and Chief Executive Officer of Nabors, in which capacity
he has served since 1988. Nabors owns and operates almost 600 land drilling and
933 land workover and well-servicing rigs worldwide. Offshore, Nabors operates
44 platform, 17 jack-up and three barge rigs in the domestic and the
international markets. These rigs provide drilling, workover and well-servicing
services. Nabors also operates 30 marine transportation and support vessels,
primarily in the Gulf of Mexico. In addition, Nabors manufactures top drives and
drilling instrumentation systems and provides comprehensive oilfield hauling,
engineering, civil construction, logistics and facilities maintenance, and
project management, services. Nabors participates in most of the significant
oil, gas and geothermal drilling markets in the world.

         During the last five years, the Registrant has not been convicted in
any criminal proceedings (excluding traffic violations or similar misdemeanors).
During the last five years, the Registrant has not been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction as a
result of which proceeding he was or is subject to a judgment, decree or final
order enjoining future 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

         In 1988 the Registrant initially acquired beneficial ownership of
Shares pursuant to Nabors' plan of reorganization confirmed by the United States
Bankruptcy Court for the Southern District of New York. Since 1988, the
Registrant has acquired beneficial ownership of Shares through purchases paid
for with Registrant's personal funds and through options granted pursuant to
employee benefit plans of Nabors, including the Registrant's employment
agreement with Nabors. No part of the consideration for any of the Shares
beneficially owned by the Registrant which he has already acquired constituted
borrowed funds, nor does he plan to borrow to acquire any of the Shares he
beneficially owns, but has not yet acquired.

ITEM 4. PURPOSE OF TRANSACTION

         Since 1988, the Registrant's acquisitions of the Shares he beneficially
owns were for investment purposes. As Chief Executive Officer and Chairman of
the Board of Nabors, the Registrant, together with Nabors' Board of Directors
and subject to his fiduciary duties to Nabors, has the power to and does
influence Nabors' affairs and management in the ordinary conduct of Nabors'
business. Registrant has no present plans which would result in a material
change in Nabors' business or corporate structure. Nevertheless, Registrant
intends to continue to exercise



                                  Page 3 of 6


his authority in the ordinary conduct of Nabors' business and will consider
plans and proposals as they are presented.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

         As of the close of business on July 22, 2002, the Registrant
beneficially owns 11,620,638 Shares comprised of (i) 1,325,559 Shares; and (ii)
currently exercisable options to purchase an aggregate of 10,295,079 Shares at
exercise prices ranging from $12.50 per Share to $46.50 per Share. 11,567,621
Shares are held directly by the Registrant and 53,017 Shares are held indirectly
through a partnership of which the Registrant is a partner.

         Registrant specifically disclaims beneficial ownership of an aggregate
of 349,094 Shares beneficially owned by his spouse which have been excluded from
the Shares listed above.

         Registrant's beneficial ownership, excluding the 349,094 Shares
beneficially owned directly or indirectly by his spouse of which Registrant
disclaims beneficial ownership, constitutes approximately 7.5% of the
outstanding Shares, based on 144,429,630 Shares outstanding on July 31, 2002, as
reported by Nabors on its Form 10-Q for the quarterly period ended July 30,
2002, as filed with the Securities and Exchange Commission (the "Commission") on
August 14, 2002 and increased by the Shares beneficially owned by the Registrant
which are issuable pursuant to options exercisable within 60 days of this
filing.

         The Registrant has the sole power to vote or direct the vote and the
sole power to dispose or direct the disposition of 11,567,621 Shares and shares
the power to vote or direct the vote and shares power to dispose or direct the
disposition of 53,017 Shares reported hereby.

         The following represents all of the transactions in the Shares by the
Registrant during the past 60 days:

         On July 22, 2002, options to purchase an aggregate of 1,900,000 Shares
vested. The options, granted by Nabors pursuant to an employee benefit plan on
January 22, 2002, are exercisable for $27.05 per share.

         On June 24, 2002 Nabors completed its reorganization pursuant to which
Nabors Industries, Inc. became an indirect subsidiary of Nabors and each share
of common stock, par value $0.10 per share, of Nabors Industries, Inc.
outstanding immediately prior to the reorganization automatically converted into
the right to receive a Share, and each option to purchase shares of Nabors
Industries, Inc. common stock outstanding immediately prior to the
reorganization, automatically converted into the right to receive an option to
purchase a Share.
