Schlumberger Announces First-Quarter 2008 Results



    Schlumberger Limited (NYSE:SLB) today reported first-quarter
    revenue of $6.29 billion versus $6.25 billion in the fourth quarter of
    2007, and $5.46 billion in the first quarter of 2007.

    Income from continuing operations before charges and credits was
    $1.30 billion--a decrease of 5% sequentially, but an increase of 10%
    year-on-year. Diluted earnings-per-share from continuing operations
    was $1.06, versus $1.11 before charges and credits in the previous
    quarter, and $0.96 in the first quarter of 2007.

    Net income, including discontinued operations, was $1.34 billion
    or $1.09 per share-diluted, compared to $1.12 in the previous quarter

    and $0.96 in the first quarter of 2007.

    Oilfield Services revenue of $5.60 billion increased 3%
    sequentially and 18% year-on-year. Pretax segment operating income of
    $1.50 billion decreased 2% sequentially but increased 7% year-on-year.

    WesternGeco revenue of $676 million decreased 15% compared to the
    prior quarter and 4% year-on-year. Pretax segment operating income of
    $196 million decreased 28% sequentially and 26% year-on-year.

    Schlumberger Chairman and CEO Andrew Gould commented, "Seasonal
    factors and weather-related events, as well as lower product and
    software sales following the exceptional levels in the fourth quarter

    had a general dampening effect on sequential revenue gains with a
    consequent effect on margins.

    "Integrated Project Management activity in Mexico continued its
    rapid new-project ramp up with an additional seven drilling rigs being
    deployed in the quarter, which resulted in heavy initial start-up
    costs being incurred.

    "At WesternGeco, results fell sequentially as Multiclient revenues
    declined steeply from the record levels of the fourth quarter of 2007.
    The Gulf of Mexico lease sale late in the first quarter, coupled with
    the increased cost of wide-azimuthal data sets that are fast becoming
    the norm for new Multiclient purchases, delayed new sales activity
    until customers absorb the results of the March leasing round. We
    expect the uneven pattern in Multiclient activity to likely persist
    throughout the year.

    "In the absence of a severe global recession leading to a steep
    drop in demand, the thin cushion of excess oil supply and the failure
    to stem decline rates in many countries, coupled with the
    higher-than-expected drawdown of US natural gas storage, are all
    factors that lead us to conclude that growth will strengthen as the
    year progresses.

    "We remain convinced that current investment levels are
    insufficient to both stem decline and to explore and develop new
    reserves and, as a result, we anticipate that the current cycle of
    exploration and production spending will remain stronger for a longer
    period than we originally anticipated."

    Other Events

    -- As part of the previously announced 40-million share

    repurchase program approved by the Board of Directors in the

    second quarter of 2006, Schlumberger repurchased 7.0 million

    shares of common stock at an average price of $81.16 for a

    total of $564 million in the quarter. As of March 31, 2008

    Schlumberger had repurchased 36.9 million shares of common

    stock at an average price of $74.15 for a total of $2.73

    billion and had remaining authorization to repurchase

    3.1 million shares of common stock.

    corporate expenses, interest income, interest expense, amortization of
    certain intangible assets, interest on postretirement medical benefits
    and stock-based compensation costs, as these items are not allocated
    to the segments.

    Oilfield Services

    First-quarter revenue of $5.60 billion was 3% higher sequentially
    and 18% higher year-on-year. Sequential revenue increases were highest
    in the Canada, US Gulf Coast, South Russia, Australia/Papua New
    Guinea, West & South Africa and Alaska GeoMarkets*. In addition

    double-digit growth rates were recorded by the North Russia

    Thailand/Vietnam, Continental Europe and Caspian GeoMarkets. Among the
    Technologies, demand was strongest for Wireline, Drilling &
    Measurements, Well Services and Well Testing services. Sequential
    revenue also grew through inclusion of FRAMO revenue in the
    Europe/CIS/Africa Area following the acquisition, in the prior
    quarter, of a majority stake in the company. However, overall
    sequential growth was moderated by operational delays in the North
    Sea, project transitions and delays on Integrated Project Management
    (IPM) activities in Latin America, and seasonal weather-related
    reductions in the China/Japan/Korea GeoMarket. Lower sales of
    Schlumberger Information Solutions (SIS), Completions and Artificial
    Lift Systems products were also recorded following the seasonal highs
    of the prior quarter.

    First-quarter pretax operating income of $1.50 billion decreased
    2% sequentially but increased 7% year-on-year. Sequential growth was
    recorded through demand for high-margin Wireline and Drilling &
    Measurements services in the US Gulf Coast; strong demand for Wireline
    and Well Services technologies in Canada; and higher activity levels
    with a more favorable technology mix in East Mediterranean

    Australia/Papua New Guinea and Thailand/Vietnam. However, this growth
    was more than offset by the impact of the seasonal land access
    restrictions in US West; a less favorable activity mix in the North
    Sea; project delays in Peru/Colombia/Ecuador; higher IPM project
    startup and third-party managed costs in Mexico/Central America; the
    weather-related slowdown in China/Japan/Korea; and an overall
    reduction in Completions and Artificial Lift Systems product sales
    together with reduced high-margin SIS sales across all Areas. These
    events resulted in an overall pretax operating margin of 26.8%.

    During the quarter, Schlumberger formally opened the new Siberian
    Training Center in Tyumen, West Siberia. The facility includes
    classrooms, workshops, fully equipped laboratories and test wells to
    provide Schlumberger geoscientists, field engineers, field technicians
    and maintenance engineers from the Russian Federation and
    Russian-language countries with technology skills in artificial lift

    directional drilling, well cementing and stimulation, data services
    and information solutions as well as in integrated project management.
    The training capacity is expected to double over the next year to
    reach 350 students.

    North America

    Revenue of $1.42 billion increased 6% sequentially and 3%
    year-on-year. Pretax operating income of $363 million increased 7%
    sequentially but decreased 16% year-on-year.

    Sequentially, the US Gulf Coast GeoMarket continued to grow
    following the return of deep-water rigs together with stronger demand
    for Wireline and Drilling & Measurements exploration services. Growth
    was also registered in Canada, resulting from a robust winter drilling
    season with high demand for Wireline and Well Services technologies

    as well as in Alaska due to strong demand for exploration-related
    services. This performance was partially offset by the seasonal land
    access restrictions in US West, the impact of weather on operations in
    US North, and lower Completions and SIS product sales across the Area.

    Pretax operating margin for the Area increased sequentially to
    25.6% due to a more favorable exploration-driven activity mix and
    higher operating leverage in the US Gulf Coast, Canada and Alaska
    GeoMarkets. This was partially offset by a lower pricing environment
    for well-stimulation-related activities in US Central, lower
    efficiency in US West, and reduced Area-wide high-margin SIS product
    sales.

    Schlumberger deployed a number of advanced Drilling & Measurements
    technologies on the Bob North #3 well for Chevron in the US Gulf of
    Mexico. On this deep-water, sub-salt exploration well, StethoScope*
    and sonicVISION* services were used to optimize mud weight within
    narrow margins while PowerDrive X5* technology improved drilling rates
    and maintained an in-gauge wellbore through the salt and rubble zones.
    In addition, the PowerDrive Xceed* system was used to successfully
    perform a deep sidetrack operation in a matter of hours rather than
    days. Despite being the second most complex well this customer had
    ever attempted, it was completed in 143 days versus a planned 191.

    As a result of previous success, Goodrich Petroleum selected Well
    Services PerfFRAC*+ technology--a member of the Contact* family of
    staged fracturing and completion services--to improve fracturing
    efficiency in 23 wells in its field in Cotton Valley in East
    Texas. The campaign increased estimated ultimate recovery by 10%

    reduced completion costs by 25%, and decreased completion time and
    gas-to-market time by 92 days for the 23 wells.

    In Western Canada, BP used real-time ACTive* Matrix service--a
    member of the ACTive family of coiled-tubing services--to stimulate a
    two-branch multilateral open-hole completion in a naturally fractured
    dolomite formation. Using ACTive real-time bottomhole pressure and
    temperature measurements increased the accuracy of the stimulation
    treatments. A subsequent distributed temperature survey (DTS)
    confirmed that the treatment successfully diverted the acid and
    stimulated the targeted zones.

    In the Canadian Arctic, Schlumberger worked with the Japan Oil

    Gas and Metals National Corporation, Natural Resources Canada, and the
    Aurora Research Institute to conduct the world´s first
    de-pressurization test of gas hydrates in the Mackenzie Delta. The
    project used services and technologies from Schlumberger IPM and
    Artificial Lift, in addition to Well Testing Vx* multiphase meters

    Completions MeshRite* sand screens, and Well Services ARCTICSET*
    cementing blends. Reservoir parameters were monitored in real time by
    the Schlumberger technology center in Fuchinobe, Japan.

    In a tight gas sand formation in South Texas for Kaler Energy
    Corporation, Schlumberger Data & Consulting Services (DCS) identified
    and predicted economic production from sands thought to be
    water-producing that were going to be bypassed. The sands were
    perforated and resulted in an initial gas production rate of 3 MMcf/d.

    In Canada, an operator used FUTUR* active set-cement technology to
    cement two wells in an active geological area of the Central Alberta
    Foothills where maintaining cement integrity has been problematic.
    More than a year after deployment, the wells have developed no
    casing-head pressure or surface casing venting.

    Latin America

    Revenue of $922 million decreased 2% sequentially but increased
    27% year-on-year. Pretax operating income of $185 million decreased
    11% sequentially but increased 14% year-on-year.

    Sequential revenue growth was recorded in the Venezuela/Trinidad &
    Tobago GeoMarket due to higher demand for Drilling & Measurements

    Wireline and Well Services technologies together with increased SIS
    product sales. However, this growth was more than offset by project
    transitions and delays in Peru/Colombia/Ecuador and Mexico/Central
    America, and lower Artificial Lift Systems and SIS product sales in
    Brazil.

    Pretax operating margin declined sequentially to 20.1% primarily
    due to higher IPM project startup and third-party managed costs in the
    Mexico/Central America GeoMarket. An unfavorable activity mix in both
    Peru/Colombia/Ecuador and Brazil together with reduced high-margin SIS
    and Artificial Lift Systems product sales also contributed to this
    result.

    In Brazil, Petrobras awarded Schlumberger a multi-year contract to
    deploy a full range of exploration and development testing services

    including exploration testing and production clean-up, as well as PVT
    sampling and analysis. With this award, further opportunities exist
    for Schlumberger Testing Services to introduce additional key
    technologies.

    In Colombia, Schlumberger Drilling & Measurements PowerDrive X5*
    rotary steerable services and PeriScope* bed boundary mapping
    technology have been used for Mansarovar in the Girasol 1 horizontal
    well to keep the horizontal section entirely within the reservoir. As
    part of the same project, work has started on the Girasol 2
    multilateral well in which four legs will be drilled with the same
    technologies--PowerDrive X5 and PeriScope. Real-time operations
    support center processes and personnel have been key to this project.
    Also in Colombia, BP achieved substantial drilling efficiencies using
    PowerDrive X5 technology on a 14 3/4-in hole section running to 4,661
    ft for 303 hours--221 hours of which were on-bottom drilling.

    Elsewhere in Colombia, Ecopetrol awarded Schlumberger a contract
    to create the Prospects Generation Center. This facility, a key
    component of Ecopetrol exploration initiatives, will combine the
    interpretation and engineering expertise of Schlumberger DCS with the
    advanced technologies of SIS. DCS geoscientists will work in groups to
    identify exploration prospects.

    Europe/CIS/Africa

    Revenue of $1.9 billion increased 7% sequentially and 24%
    year-on-year. Pretax operating income of $500 million increased 1%
    sequentially and 16% year-on-year.

    Sequential revenue growth was driven by higher Artificial Lift
    Systems product sales and increased market penetration for Well
    Services technologies in South Russia; strong demand for Well Services
    technologies in Continental Europe; higher demand for Drilling &
    Measurements technologies in West & South Africa and the Caspian;
    higher IPM and Drilling & Measurements activities in North Russia; and
    by the consolidation of FRAMO revenue. This was partially offset by
    operational delays in the North Sea GeoMarket, the seasonal impact of
    winter weather in East Russia, and lower SIS product sales across the
    Area.

    Pretax operating margin declined sequentially to 26.3% due to an
    unfavorable activity mix in the North Sea, lower-margin Artificial
    Lift Systems product sales in South Russia, reduced high-margin
    Area-wide SIS product sales, and the effect of consolidation of FRAMO
    revenue in the Area.

    Offshore Ivory Coast, Schlumberger Testing Services successfully
    introduced PURE* perforating systems for clean perforations technology
    for independent operator Foxtrot International. The first job was
    designed to provide dynamic underbalanced conditions and data
    confirmed the well-bore pressure to have remained below formation
    pressure during perforation. The well subsequently flowed without
    stimulation at a rate that exceeded customer expectations. Based on
    this success, Foxtrot International intends to further deploy the
    technique.

    In Algeria, First Calgary Petroleum (FCP) used the Schlumberger
    SensaLine* fiber-optic slickline monitoring system to assist in
    detecting a leak in a bridge plug set to isolate a productive lower
    zone while running production tests on the upper zone. Real-time
    THERMA* temperature analysis software enabled FCP to detect a leak
    originating from the bridge plug and subsequently evaluate the flow
    contribution from the lower zone. Schlumberger Testing Services also
    completed a fourth SensaLine distributed temperature survey (DTS) for
    ConocoPhillips in Algeria.

    In Angola, Schlumberger Drilling & Measurements Scope*
    logging-while-drilling and PowerDrive rotary steerable technologies
    were deployed on the Gimboa field for Sonangol P&P. The success of the
    technologies in drilling the Gimboa horizontal well led to their use
    on a subsequent lateral drainhole that represents the longest-ever
    horizontal well drilled in Angola. Operations were monitored remotely
    from a Schlumberger OSC* Operations Support Center installed in the
    customer´s office. The lateral drainhole was positioned using Scope
    technology resulting in a net pay greater than 70%.

    In the Congo, Societe Nationale des Petroles du Congo (SNPC)
    selected SIS software for their Kundji Bindi Asset Team interpretation
    platform. The team will use Petrel* seismic-to-simulation, IP
    (Interactive Petrophysics), OFM* well and reservoir analysis and
    PIPESIM* production analysis software to develop a plan for
    redevelopment of the Kundji and Bindi reservoirs that represents a
    strategic milestone for SNPC.

    In Italy, STOGIT, the ENI subsidiary responsible for natural gas
    storage, has implemented Well Services FUTUR* active set-cement
    technology as part of a three-year, 50-well campaign to develop gas
    storage wells. This unique self-healing cement system was deployed in
    order to prevent the leakage of stored gas that could be detrimental
    to the environment and require expensive well repair or
    abandonment. Since using FUTUR technology as part of their standard
    cementing operations, STOGIT has not experienced any problems with
    leaking wells or loss of zonal isolation.

    Middle East & Asia

    Revenue of $1.32 billion decreased 2% sequentially but increased
    22% year-on-year. Pretax operating income of $460 million decreased 2%
    sequentially but increased 24% year-on-year.

    Sequentially, the Australia/Papua New Guinea GeoMarket grew with
    exploration-driven demand for Wireline and Well Testing services.
    Sequential growth was also registered in the Gulf, East Mediterranean
    and Thailand/Vietnam GeoMarkets with strong demand for Wireline, Well
    Testing and Well Services technologies. However, this performance was
    more than offset by the impact of winter weather in the
    China/Japan/Korea GeoMarket together with lower Completions and
    Artificial Lift Systems product sales across the Area.

    The pretax operating margin of 34.9% was essentially flat compared
    to the prior quarter with a more favorable activity mix in the
    Australia/Papua New Guinea, East Mediterranean, Gulf and
    Thailand/Vietnam GeoMarkets being offset by the slowdown in
    China/Japan/Korea together with a lower-margin activity mix for
    Drilling & Measurements services in the Area.

    In Qatar, Qatargas awarded a two-year contract to Schlumberger
    Testing Services to provide high-rate clean-up and testing for the
    development of 33 natural gas wells in the North Field. The wells
    belong to two separate joint ventures, Qatargas 3, with shareholders
    Qatar Petroleum, ConocoPhillips and Mitsui, and Qatargas 4, whose
    shareholders are Qatar Petroleum and Royal Dutch Shell. In order to
    capture synergies, the assets of both projects are being developed
    jointly by a single team. Among the factors taken into account in
    awarding the contract were the availability of new multiphase flow
    metering Vx technology in gas mode, and demonstrated Schlumberger
    service quality and HSE performance. This contract complements a
    previously awarded fluid sampling and analysis contract for the two
    Qatargas projects, supported by the Qatar Fluid Analysis Center--a
    Schlumberger PVT laboratory.

    Maersk Oil Qatar awarded Schlumberger Drilling & Measurements a
    two-year contract for directional drilling

    measurements-while-drilling and logging-while-drilling services for 80
    extended-reach wells offshore Qatar. The contract covers services on 6
    rigs and was based on proven technological success in 2007 when
    Drilling & Measurements passed the million-foot milestone on the Al
    Shaheen project where horizontal sections range from 18,000 ft to
    25,000 ft.

    In Kuwait, SIS was awarded a multi-year information management
    technologies and services contract by the Kuwait Oil Company for the
    provision of Corporate Data Management services, real-time production
    data E&P management software, and other information management
    projects including capabilities mapping and knowledge transfer
    services.

    In the South China Sea, an operator selected ACTive* Perf
    service--a member of the ACTive family of coiled-tubing services--to
    perforate and complete underbalanced wells to minimize formation
    damage. The deployment of ACTive Perf technology led to earlier and
    higher-than-expected production of sand-free gas.

    In India, the Schlumberger Wireline PressureXpress* reservoir
    pressure measurement service saved significant rig time for Reliance
    Industries deep-water operations over a five-month
    period--representing substantial cost savings in this expensive
    deep-water environment.

    WesternGeco

    First-quarter revenue of $676 million decreased 15% over the prior
    quarter and 4% compared to the same period last year. Pretax operating
    income of $196 million decreased 28% sequentially and 26%
    year-on-year.

    Sequentially, Marine revenue increased as both vessel utilization
    and productivity improved following the vessel dry-docks and the
    seasonal transits of the prior quarter. Data processing also recorded
    a sequential increase in revenue, but these increases were more than
    offset by a significant decrease in Multiclient revenue in North
    America following the record sales in the previous quarter. Land
    revenue also declined following project completions in North Africa
    and lower demand in the Middle East.

    Pretax operating margin declined sequentially to 29.1% as the
    increase in Marine was more than offset by the decline in high-margin
    Multiclient sales.

    Sonatrach awarded WesternGeco a Q-Land* acquisition and data
    processing project over the Hassi R´Mel field covering 2,225 sq
    km--the largest Q-Land survey to date. Acquisition commenced earlier
    in the quarter and the data will be processed at the recently opened
    WesternGeco center in Algiers.

    In the Norwegian sector of the North Sea, StatoilHydro ASA awarded
    WesternGeco multicomponent acquisition projects using Q-Seabed*
    technology. The system will deliver superior imaging and inversion
    results using the low-frequency signals made possible by the system´s
    high-fidelity technology. The projects will cover parts of the Oseberg
    Sor and Gullfaks fields. At Oseberg Sor, Q-Seabed technology will
    acquire multiazimuth data through the use of the system´s active cable
    lengths. At Gullfaks, the survey will be used as a reservoir
    monitoring tool to optimize production.

    Elsewhere in the Norwegian sector of the North Sea, StatoilHydro
    ASA awarded WesternGeco integrated 4D Q-Marine* acquisition

    processing and inversion projects covering the Norne and Heidrun
    fields including the Epsilon structure with the total area of the
    award exceeding 500 sq km. This will be the fifth survey using
    Q-Marine technology at Norne and the third at Heidrun. The surveys are
    part of ongoing efforts to maximize recovery from both fields through
    identification of unswept and partially swept areas.

    WesternGeco commenced the previously announced fourth phase of the
    multiclient E-Octopus wide-azimuth acquisition program in the US Gulf
    of Mexico. In parallel with these projects, WesternGeco
    Electromagnetics is completing 3D marine magnetotelluric inversion and
    interpretation using a dedicated computer cluster in Houston. This
    first multi-measurement constrained imaging project involves
    significant interpretation iterations of magnetotelluric, gravity and
    Q-Marine seismic data sets to produce a more precise integrated
    sub-surface model--thus reducing overall risk in this challenging
    sub-salt environment.
