         NABORS 1Q2005 NET INCOME SETS RECORD AT $0.80 PER DILUTED SHARE

ST MICHAELS, BARBADOS, APRIL 27, 2005, NABORS INDUSTRIES LTD. (AMEX: NBR) today
reported its financial results for the first quarter of 2005. Adjusted income
derived from operating activities(1) was $171.9 million compared to $85.1
million in the prior year comparable quarter and $113.8 million in the prior
quarter ended December 31, 2004. Net income was $127.4 million or $0.80 per
diluted share. This net income result compares to $71.7 million or $0.46 per
diluted share in the same period of 2004 and $108.8 million or $0.68 per diluted
share in the fourth quarter of 2004. Operating revenues and Earnings from
unconsolidated affiliates for this quarter were $785.7 million compared to
$596.8 million in the prior year comparable quarter and $684.1 million in the
fourth quarter of 2004.

Commenting on these results, Gene Isenberg, Nabors' Chairman and Chief Executive
Officer said, "Our quarterly adjusted income derived from operating activities
more than doubled, generating all-time records in net income and earnings per
share, despite a higher effective tax rate associated with the increased North
American income. Return on capital employed, one of our most important metrics,
reached 15% for the quarter on the strong operating results. The biggest
contributor to this performance was our U.S. Lower 48 Land Drilling business,
primarily as a result of substantially higher revenues as demand for rigs
continues to be strong in the face of limited supply. High activity levels and
tight supply characterized nearly all of our other drilling and well servicing
markets, with Alaska and the shallow U.S. Gulf of Mexico being the only notable
exceptions. Our U.S. Land Well Servicing unit derived significant pricing
improvement as supply/demand reached equilibrium for both our rigs and trucks.
This quarter was also bolstered by an all-time record quarter in Canada, the
start-up of several rigs in our International unit and improving results in our
Other Operating Segments.

"Compared to the immediately preceding fourth quarter of 2004, adjusted income
derived from operating activities increased by more than 75% in our U.S. Lower
48 Land Drilling operations, primarily on higher average margins. Canada
achieved an increase of 50% with the seasonally high activity associated with
the winter season bolstered by significantly higher average dayrates. Our U.S.
Land Well Servicing operations saw a nearly 30% sequential increase as modestly
higher rig hours were overshadowed by a significant increase in the average
hourly rate for both rigs and trucks. We also experienced a significant increase
our in international results, although the initial contribution of several
long-term contracts, most notably in Saudi Arabia, was


- ---------------------
(1) Adjusted income derived from operating activities is computed by:
subtracting direct costs, general and administrative expenses, depreciation and
amortization, and depletion expense from Operating revenues and then adding
Earnings from unconsolidated affiliates. Such amounts should not be used as a
substitute to those amounts reported under accounting principles generally
accepted in the United States of America (GAAP). However, management evaluates
the performance of our business units and the consolidated company based on
several criteria, including adjusted income derived from operating activities,
because it believes that this financial measure is an accurate reflection of the
ongoing profitability of our company. A reconciliation of this non-GAAP measure
to income before income taxes, which is a GAAP measure, is provided within the
table set forth immediately following the heading "Segment Reporting."




partially offset by timing delays and temporary lulls in activity in some other
areas. Our U.S. Offshore unit posted modestly higher results on higher
utilization of its workover jackup and platform rigs, coupled with some
improvement in pricing. Our Other Operating Segments have returned to a
meaningful level of profitability with higher activity in almost every
component. Alaska was up sequentially with the winter exploratory season but
down compared to last year.

"We expect the remainder of this year to significantly surpass our previous
expectations, with higher average pricing in most of our businesses and further
increases in international rig activity. In our U.S. Lower 48 Land Drilling
operation we expect substantial gross margin improvements throughout the year
although less than the $1,650 per rig, per day sequential increase we achieved
this quarter. Recently we have seen an increase in customer interest in
longer-term contract durations at higher dayrates, so as to secure the
efficiencies associated with a continuous work program and quality crews and
rigs.

"We expect the industry to continue to add capacity at a limited pace in
response to the continuing increase in rig demand. However, it must be
emphasized that compared to any time in the recent past, rig and component
equipment costs are higher and lead times longer, which should minimize
oversupply concerns. Nabors enjoys a relatively favorable position to
accommodate this demand in terms of capital cost and time advantages due to our
long-standing key relationships with suppliers and steady order flow. This also
gives us the flexibility to adjust the pace of our rig remanufacturing and
upgrade program to suit the market, although our current plans are to continue
at a pace of only four to five rigs per quarter. Our emphasis is on like-new
remanufactured rigs which incorporate the latest technologies and new innovative
configurations to facilitate improved drilling efficiency and faster moves in
both over-the-highway and on-pad applications. Most of these rigs are readily
adaptable to fit the requirements of any of our U.S. Lower 48 Land Drilling,
International or Canadian operations, and utilize Nabors' proprietary A/C PLC
(Programmable Logic Control) systems. We have already deployed a large number of
these rigs, with several configured for pad drilling in the Canadian tar sands
and the U.S. Rocky Mountains.

"Canada is on track for a record year despite an early arrival of the spring
thaw, with indications of higher than usual activity throughout the spring,
summer and fall periods, weather permitting. We recently commissioned the first
of our innovative A/C coiled tubing / drill pipe drilling rigs and have
initiated plans to construct additional units. Internationally, we also expect a
record year as the contributions of the last of the ten new Saudi Arabian
contracts commence in the second quarter and temporarily idle rigs in other
venues return to work. Ongoing strong demand internationally, particularly for
higher horsepower rigs, coupled with previously identified prospects bodes well
for sustained growth in our international results.

"The strong demand for well servicing and workover rigs is being reflected in
significant price increases in our U.S. Land Well Servicing business. We expect
this pricing momentum to continue for the next few quarters as increases take
effect across the full fleet and the contribution from our new millennium rigs
begins at the rate of two per month early in the third quarter. Our U.S.
Offshore business is forecasting steady but modest improvement for the remainder
of the year, as is the case for our Other Operating Segments and Oil and Gas
operations. Alaska remains the only unit that expects lower results both
sequentially and year-over-year, but there is emerging upside from the pending
development of heavy oil deposits and some recent discoveries, followed by the
prospects for opening of the Arctic National Wildlife Refuge (ANWR) in the
longer-term.

"The current cycle represents the first time I have seen this many of our
individual business units performing well simultaneously and exhibiting a solid
upward bias. The continuing high commodity price environment is a direct
indication that supply challenges persist and is enabling our customers to
continue generating returns well in excess of their costs of capital, even in
the face of higher costs. Additional drilling will be needed for an extended
period to meet these supply challenges, and our ongoing investment in rig
upgrades and renovations are a significant factor in the improved drilling
efficiencies that are mitigating the impact of higher costs on our




customers' economics. Nabors' established global infrastructure and the largest
procurement and supply chain management systems in our industry uniquely
position us to be the most competitive source of incremental rigs both
internationally and in North America. While we expect strong earnings growth
from our international unit and eventually other areas like ANWR, the near-term
will be dominated by the almost daily favorable developments emanating from our
North American land operations."

The Nabors companies own and operate almost 600 land drilling and approximately
870 land workover and well servicing rigs worldwide. Offshore, Nabors operates
43 platform rigs, 19 jack-up units, and three barge rigs in the United States

</Table>


(1)   Diluted earnings per share for the three months ended March 31, 2004 and
      December 31, 2004 reflects the assumed conversion of our $1.381 billion
      zero coupon convertible senior debentures due 2021, as the conversion in
      those periods would have been dilutive. Diluted earnings per share for the
      three months ended March 31, 2005 excludes approximately 8.5 million
      potentially dilutive shares initially issuable upon the conversion of
      these debentures. Such shares did not impact our calculation of diluted
      earnings per share for that period as we are required to pay cash up to
      the principal amount of any debentures converted resulting from the
      issuance of a supplemental indenture relating to the debentures in October
      2004. We would only issue an incremental number of shares upon conversion
      of these debentures, and such shares would only be included in the
      calculation of the weighted-average number of shares outstanding in our
      diluted earnings per share calculation, if the price of our shares
      exceeded approximately $95.

(2)   Diluted earnings per share for the three months ended March 31, 2005 and
      2004 and December 31, 2004 excludes approximately 10.0 million potentially
      dilutive shares initially issuable upon the exchange of our $700 million
      zero coupon senior exchangeable notes due 2023. Such shares did not impact
      our calculation of diluted earnings per share for these periods as we are
      required to pay cash up to the principal amount of any notes exchanged. We
      would only issue an incremental number of shares upon exchange of these
      notes, and such shares would only be included in the calculation of the
      weighted-average number of shares outstanding in our diluted earnings per
      share calculation, if the price of our shares exceeded $70.10.

(3)   Includes the following weighted-average number of common shares of Nabors
      and weighted-average number of exchangeable shares of Nabors Exchangeco,
      respectively: 152.0 million and .2 million shares for the three months
      ended March 31, 2005; 147.6 million and .4 million shares for the three
      months ended March 31, 2004; and 149.6 million and .2 million shares for
      the three months ended December 31, 2004. The exchangeable shares of
      Nabors Exchangeco are exchangeable for Nabors common shares on a
      one-for-one basis, and have essentially identical rights as Nabors
      Industries Ltd. common shares, including but not limited to voting rights
      and the right to receive dividends, if any.
