   NABORS POST RECORD YEAR AND QUARTER AT $4.07 AND $1.35 PER DILUTED SHARE,
                           EXCLUDING LITIGATION AWARD

HAMILTON, BERMUDA, FEBRUARY 6, 2006, NABORS INDUSTRIES LTD. (NYSE: NBR), today
announced its results for the fourth quarter and full year ended December 31,
2005. Adjusted income derived from operating activities(1) increased 157% to
$292.2 million for the fourth quarter compared to $113.8 million in the fourth
quarter of 2004 and $241.9 million in the third quarter of this year. Net income
increased by 104% to $221.6 million ($1.35 per diluted share) for the fourth
quarter compared to $108.8 million ($0.68 per diluted share) in the fourth
quarter of 2004 and $178.9 million ($1.11 per diluted share) in the third
quarter of this year, excluding the effect of an interim litigation award
(discussed below) entered against the Company late this afternoon in the amount
of $25.6 million (plus attorneys fees and costs). After taking into account the
effect of the litigation award, net income for the fourth quarter was $210.6
($1.29 per diluted share). For the full year ended December 31, 2005, adjusted
income derived from operating activities rose by 167% to $879.8 million,
compared to $329.7 million in 2004. Net income for 2005 was $659.7 million
($4.07 per diluted share) compared to $302.5 million ($1.92 per diluted share)
in 2004, excluding the effect of the litigation award. After taking into account
the effect of the litigation award, net income for the full year was $648.7
($4.00 per diluted share).(2)

Gene Isenberg, Nabors' Chairman and CEO, commented on the Company's results.
"Our fourth quarter and full year results set records as the underlying strength
of our operations easily overcame several factors, such as downtime on offshore
rigs due to hurricane repairs and regulatory recertification, asset retirement
charges and a higher effective tax rate. Meaningful year-over-year improvements
were achieved in each of our operating units, led by our US Lower 48 Land
Drilling business which posted a fivefold increase. Our US Land Well-Servicing
and US Offshore businesses nearly doubled, while Canada and International both
gained over 50%. Our Other Operating Segments also made a significant
contribution following a loss in 2004. All of this resulted in new records in
return on average capital employed as the Company posted 24% in the quarter and
19% for the year. Nabors' ability to deploy growth capital and generate
substantially assured returns of greater than 20% is unmatched in our history
and probably the industry.


     ----------

     (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."

     (2) The Company also is presenting net income and earnings per share
     numbers before and after the effect of an interim litigation judgment
     against the Company late this afternoon in the amount of $25.6 million,
     plus an undetermined amount of attorneys fees and costs. The Company is
     including the adjusted net income number because management believes the
     non-GAAP financial measure to be more indicative of the Company's ongoing
     operating results and financial condition.





"Customer acceptance of our new rigs is proceeding at an extraordinary pace and
is best evidenced by the 21 new awards we have received in the seven weeks since
our December 14th analyst meeting. This brings the total number of term
contracts securing new built rigs to 82 in less than 13 months, making our
previous projection of 100 new rig contracts company wide by mid 2007 readily
achievable. In addition, 8 existing rigs are completing
reactivation/refurbishment before beginning term contracts, with another 10
expected to be completed and operating under term contracts by year's end.

"Meanwhile the pace of margin improvement continues to exceed our expectations
in virtually every area of our business, with our US Lower 48 operations
achieving a margin increase of $4,250 per rig day for the year and $1,031 per
rig day for the sequential quarter with the fourth quarter averaging $8,634 per
rig day and nearly $10,500 per rig day in our Canadian drilling business. Demand
for rigs continues unabated and customer commitments and forward plans lead us
to believe that a shortfall in rig supply will persist for several years. The
visibility of our future results has never been better with the magnitude of
current and prospective term contracts assuring an increasing proportion of our
income expectations throughout all of our rig units. However, we still retain a
high degree of discretion as to the proportion of our existing fleet that is
committed to term contracts or exposed to spot market pricing and new build
tie-in opportunities.

"Our US Lower 48 Land Drilling business realized the largest increase in
results, largely on the strength of increased pricing and refurbished rigs.
Demand for rigs remains strong against a constrained supply and this imbalance
continues to increase pricing faster than we previously anticipated. An
increasing proportion of this unit's future growth will be derived from new
built rigs, virtually all with three year contracts. This is evident by the 10
commitments we have received since our mid-December analyst meeting, bringing
the total number of new rig commitments in the last nine months to 57. The
certainty of future results is being enhanced by term contracts on existing
rigs, which increased by 15 to 112 out of the 255 currently working. Safety,
performance and efficiency are also at extraordinarily high levels, particularly
when you consider that in the last three years this unit increased its aggregate
man-hours worked by 132% to over 15 million in 2005 while reducing the number
and severity of lost time incidents by almost 60% to 0.17 per 0.2 million
man-hours.

"Canada set a new quarterly and full year record, surpassing the customarily
peak first quarter by over 30% and the previous year by 50% on the strength of a
substantial increase in margins and unseasonably high activity late in the year.
The performance in the fourth quarter, where results were nearly double the
prior year, portends a new record for the first quarter and full year 2006 with
an expectation of even higher utilization and margins. In recent weeks Canada
has also secured five commitments for new PACE rigs and expects to roll out
three of our new coiled tubing/stem drilling rigs in the first quarter. These
rigs have abundant opportunities in both Canada and the US Lower 48.

"Our US Land Well-Servicing business achieved an 87% increase in 2005, ending
the year with a record performance in what is traditionally the weakest quarter
of the year. This was fueled by significantly higher pricing and a less than
normal seasonal decline in rig hours worked. This is indicative of the strength
of demand in this market, which is leading to further price increases in the
first quarter. We also continue to see further opportunities for investment in
this area.

"Our US Offshore unit saw an 88% increase in its full year results, despite a
significantly weaker fourth quarter following the hurricanes. Not only did we
lose revenue from multiple rigs under repair, but we also saw a number of
projects postponed or cancelled by various customers. Our Barge Rig 300 returned
to service last week and our jackup rig 54 is nearly ready to return to work.
The outlook for this business is very strong with substantial increases in
jackup rates exerting the greatest impact. During the second half of the year we
expect to see even greater improvement with the deployment of Barge 301 and
SuperSundowners(R) XX and XXI, all new rigs currently under construction.





"Our International results increased by over 50% during 2005 and should see an
even larger increase in 2006, primarily in the second half as the effects of
multiple rig repricings and 18 incremental rig deployments are realized.
Commencement of 11 of these rig contracts will occur in the first half
including: Dolphin 111 jackup offshore Angola; the newly constructed MODS 175
rig for offshore New Zealand; the first two of four platform rigs (two MASE and
two SuperSundownwers) awarded by PEMEX for offshore Mexico; and seven land rigs,
six newly constructed and one refurbished. These land rigs will be deployed in
Saudi Arabia, Venezuela, Algeria, and Oman. Another two PACE rigs will commence
operations in Saudi Aramco in the third quarter of 2006. This unit also was the
recipient of seven new PACE rig awards in the last few weeks, all of which are
expected to commence in 2006. The awards are for term contracts in Saudi Arabia
(2), Oman (2), Libya (1), Tanzania (1) and Brunei (1). There remain a large
number of current and prospective opportunities for additional new PACE rigs.
International's fourth quarter 2005 results were dampened by downtime associated
with two jackups in dry-dock for much of the quarter due to regulatory
recertification, a situation that will also effect the first quarter.

"Our Other Operating Segments continue to improve at a rapid rate led by our
Marine Transportation unit. Ryan, Canrig and EPOCH also fueled the increase with
each showing sequential improvement of over 40%.

"During the quarter we continued to effect our stock buyback program with a
repurchase of 289,100 additional shares at an average price of $65.39. This
brings 2005's total purchases to 1,789,100 shares at an average price of $55.60
per share. We also expect to redeem for cash virtually all of our approximately
$827 million (accreted value) in zero coupon convertible Senior Debentures due
2021 given that today is the first of a series of opportunities that occur on
each fifth anniversary for holders to redeem the debentures. We will announce
the magnitude of the redemption as soon as the final amount is known.

"During the quarter we were the defendant in a class-action arbitration hearing
regarding compensation issues brought on behalf of field employees of our
well-servicing unit operations in California. Late this afternoon, we received
an interim judgment against the Company in the amount of $25.6 million (plus an
undetermined amount of attorneys fees and costs), which was in excess of
reserves established by the Company in the amount of $10.6 million as of
September 30, 2005. Given the timing of the award, we have not yet had an
opportunity to fully consider the arbitrator's decision.

"In summary, all of the developments we experienced throughout 2005 and
particularly during the fourth quarter served to further reinforce our
conviction in the strength and duration of this cycle. We are focused on
capturing a disproportionate share of the increasing global demand for new and
existing rigs. Our success to date in this effort is indicative of the inherent
advantages we enjoy and is resulting in a substantially larger and newer global
fleet underwritten with long-term contract commitments. This is providing us
with the highest degree of performance visibility in our history and I look
forward to continue reporting results that exceed even our optimistic
projections."

(1) Results presented for the three months and year ended December 31, 2005
    exclude the incremental impact of $11 million, net of tax, related to an
    interim litigation award entered against the Company on February 6, 2006.
    The interim judgment totaled $25.6 million on a pretax basis (plus an
    undetermined amount of attorney's fees and costs), which was in excess of
    reserves established by the Company of $10.6 million (pretax) as of
    September 30, 2005. We have provided a reconciliation below of net income,
    as presented herein, to net income including the incremental impact of the
    interim litigation award (its nearest comparable GAAP financial measure) and
    diluted earnings per share, as presented herein, to diluted earnings per
    share including the incremental impact of the interim litigation award (its
    nearest comparable GAAP financial measure). The Company included these net
    income and diluted earnings per share amounts in the release even though
    these amounts exclude the incremental impact of the litigation award because
    management believes these non-GAAP financial measures to be more indicative
    of the Company's on-going operating results and financial condition.

(2)  See "Computation of Earnings Per Share" included herein as a separate
     schedule.

(3)  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".

(1)  Diluted earnings per share for the three months ended December 31, 2005 and
     September 30, 2005 and for the year ended December 31, 2005 excludes
     approximately 8.5 million potentially dilutive shares initially issuable
     upon the conversion of our $1.381 billion zero coupon convertible senior
     debentures. Such shares did not impact our calculation of dilutive earnings
     per share for those periods 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
     $97. Diluted earnings per share for the three months and year ended
     December 31, 2004 reflects the assumed conversion of our $1.381 billion
     zero coupon convertible senior debentures, as the conversion in those
     periods would have been dilutive.

(2)  Diluted earnings per share for the three months and year ended December 31,
     2005 reflects the assumed conversion of our $700 million zero coupon senior
     exchangeable notes resulting in the inclusion of the incremental number of
     shares that we would be required to issue upon exchange of these notes. The
     number of shares that we would be required to issue upon exchange consists
     of only the incremental shares that would be issued above the principal
     amount of the notes, as we are required to pay cash up to the principal
     amount of the notes exchanged. We would only issue an incremental number of
     shares upon exchange of these notes, and such shares are only included in
     the calculation of the weighted-average number of shares outstanding in our
     diluted earnings per share calculation, when the price of our shares
     exceeds $70.10, which was the case for the applicable measurement period
     for the three months and year ended December 31, 2005. Diluted earnings per
     share for the three months ended September 30, 2005 and December 31, 2004
     and for the year ended December 31, 2004 does not include any incremental
     shares issuable upon the exchange of our $700 million zero coupon senior
     exchangeable notes as the price of our shares did not exceed $70.10 at the
     end of those periods.

(3)  Includes the following weighted-average number of common shares of Nabors
     and weighted-average number of exchangeable shares of Nabors Exchangeco
     (Canada) Inc., an indirect wholly-owned Canadian subsidiary of Nabors,
     respectively: 157.3 million and .2 million shares for the three months
     ended December 31, 2005; 149.6 million and .2 million shares for the three
     months ended December 31, 2004; 157.0 million and .2 million shares for the
     three months ended September 30, 2005; 155.9 million and .2 million shares
     for the year ended December 31, 2005; and 148.7 million and .3 million
     shares for the year 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.
