Schlumberger Announces Third-Quarter 2007 Results



    Schlumberger Limited (NYSE:SLB) today reported third-quarter
    revenue of $5.93 billion versus $5.64 billion in the second quarter of
    2007, and $4.95 billion in the third quarter of 2006.

    Net income reached $1.35 billion--an increase of 8% sequentially
    and 35% year-on-year. Diluted earnings-per-share were $1.09 versus
    $1.02 in the previous quarter, and $0.81 in the third quarter of 2006.

    Oilfield Services revenue of $5.13 billion increased 3%
    sequentially and 19% year-on-year. Pretax business segment operating
    income of $1.51 billion was essentially flat sequentially but
    increased 23% year-on-year.

    WesternGeco revenue of $794 million increased 19% sequentially and
    20% year-on-year. Pretax business segment operating income of $306
    million increased 42% sequentially and 32% year-on-year.

    Schlumberger Chairman and CEO Andrew Gould commented, "Growth in
    the third quarter was driven by international markets particularly in
    Latin America, Russia, China and Indonesia. In North America,
    increased activity in Canada was offset by weaker pricing for pressure
    pumping in certain regions on land, and a sharp revenue drop in the
    Gulf of Mexico due to the departure of several rigs to overseas
    locations and the loss of approximately 15 operating days due to
    precautionary stand downs for approaching weather systems.

    Technology growth was strongest at WesternGeco, as the segment
    recovered from the second-quarter dry docks and vessel transits.
    Marine acquisition revenue for the quarter was an all-time record as
    advanced Q-Technology acquisition techniques continued to be deployed.
    In other Technologies, growth was led by robust IPM activity and by
    demand for Wireline and Drilling & Measurements services, particularly
    in overseas markets.

    In the immediate future, while there will be some recovery from
    low activity levels in the Gulf of Mexico, natural gas activity in
    both Canada and the US is likely to stabilize as production remains
    relatively strong and gas storage approaches winter at comfortable
    levels. As a result, pressure-pumping pricing deterioration will
    continue. The current situation does not however change our view that
    North American natural gas supply will require sustained activity to
    combat production decline, and technology to increase production rates
    from poorer quality reservoirs. Overseas, growth will continue at
    varying rates between regions due to the effects of winter weather and
    project delays in certain countries.

    Global demand for oil remains strong while non-OPEC production
    continues to disappoint. Production decline rates in mature areas and
    continuing project delays will inhibit non-OPEC supply increases,
    while personnel and equipment shortages will restrict the industry's
    ability to respond."

    Oilfield Services

    Third-quarter revenue of $5.13 billion was 3% higher sequentially
    and 19% higher year-on-year.

    Sequential revenue increases were highest in Latin America led by
    the Mexico/Central America and Peru/Colombia/Ecuador GeoMarkets
    followed by Europe/CIS/Africa, particularly in the East Russia and
    North Africa GeoMarkets, with growth also recorded in Middle East &
    Asia, led by the China/Japan/Korea and Indonesia GeoMarkets. In North
    America, the strong increase in revenue following the seasonal spring
    breakup in Canada was not enough to offset lower revenue in the US
    GeoMarkets. This was the result of a sharp revenue drop in the US Gulf
    of Mexico due to the transfer of several rigs to overseas locations
    and from the loss of approximately 15 operating days due to
    precautionary stand downs for approaching weather systems. In the
    North American pressure-pumping stimulation services market,
    capacity-driven pricing erosion continued.

    Pretax operating income of $1.51 billion was essentially flat
    sequentially but increased 23% year-on-year. Sequentially, growth
    through stronger demand for Well Services and Wireline technologies in
    Canada; a more favorable activity mix in the Mexico/Central America
    GeoMarket; higher activity levels and a favorable technology mix in
    Peru/Colombia/Ecuador; and increased high-margin Drilling &
    Measurements activity in China/Japan/Korea and Eastern Russia was
    experienced. However, this growth was more than offset by the
    weather-related effects in the US Gulf of Mexico and the
    pressure-pumping pricing erosion on land in the US. The overall
    Oilfield Services pretax operating margin was 29.4%.

    Advanced technology uptake continued during the quarter as demand
    for new Wireline technologies was driven by the need for more accurate
    formation evaluation. New Wireline Scanner* deployments included
    high-pressure, high-temperature applications in the US Gulf of Mexico,
    use for thin-bed and laminated-sand analysis in the US and West
    Africa, and for evaluation of additional natural gas production in
    Mexico. Total jobs run with Scanner technology now exceed 1,500
    worldwide, with more than 300 tools deployed. Drilling & Measurements
    Scope* services also continued their worldwide expansion with
    PeriScope* imaging-while-drilling jobs in China and TeleScope*
    high-speed telemetry in combination with StethoScope* formation
    pressure-while-drilling operations in Qatar, Brunei and the US Gulf of
    Mexico.

    North America

    Revenue of $1.30 billion decreased 3% sequentially and 3%
    year-on-year. Pretax operating income of $350 million decreased 16%
    sequentially and 15% year-on-year.

    Sequentially, revenue in the Canada GeoMarket rebounded on the
    higher rig count led by demand for Well Services and Wireline
    technologies following the seasonal spring break-up. However, this
    growth was more than offset by a slowdown in the US Gulf Coast due to
    operator caution during the hurricane season; lower exploration-driven
    activity associated with seasonal facilities and rig maintenance in
    Alaska; and the pricing erosion in pressure-pumping stimulation
    services in all three US land GeoMarkets.

    Pretax operating margin for the Area declined sequentially to
    26.9% primarily due to the weather-related effects on activity in the
    US, particularly in the Gulf of Mexico; lower high-margin exploration
    activity in Alaska; and the lower pricing environment for
    pressure-pumping stimulation services in the US land GeoMarkets. In
    Canada, however, margins grew as a result of improved utilization of
    people and equipment as activity rebounded.

    In the US Gulf of Mexico, Rt Scanner* and Sonic Scanner*--members
    of the Schlumberger Wireline Scanner Family* of rock and fluid
    characterization services--were run for the first time for BP in a
    high-pressure environment. The technologies were successfully deployed
    to a total depth of 29,300 ft where bottom-hole pressures exceeded 23
    kpsi. Coordination between the field and Schlumberger Data &
    Consulting Services (DCS) allowed delivery of high-quality dip results
    from the Rt Scanner enabling the customer to determine subsequent
    drilling plans.

    BP also deployed in the US Gulf of Mexico advanced Schlumberger
    Drilling & Measurements technologies to run a complex bottom-hole
    assembly in a hostile deep-water environment. The unique toolstring
    combination included PowerDrive* rotary-steerable systems, VISION*
    imaging-while-drilling measurements, TeleScope high-speed telemetry
    and StethoScope formation pressure-while-drilling technologies.

    Elsewhere in the US Gulf of Mexico, BHP Billiton Petroleum set a
    new benchmark for subsalt deep-water drilling by achieving a record
    average of only one-and-a-half days per 1,000 ft, utilizing
    Schlumberger Drilling & Measurements PowerDrive rotary-steerable
    technology, TeleScope high-speed telemetry and VISION resistivity
    measurements in all six hole sections.

    In Oklahoma, Devon Energy and Schlumberger DCS continued to
    develop a comprehensive formation evaluation methodology for the
    customer's horizontal Barnett Shale play. This methodology integrates
    the latest in Schlumberger seismic, logging, micro-seismic and core
    analysis technologies to develop and optimize the completion
    process. The efforts bring deeper understanding across the Barnett
    Shale play in the areas of stress analysis, fracture-height
    containment and rock mechanics--allowing for increased effectiveness
    during stimulation of these wells.

    In South Texas, Brigham Oil and Gas deployed the Rt Scanner
    triaxial induction tool to identify two laminated sand bodies that
    would have been overlooked with conventional petrophysical analysis.
    The assessment revealed 64 ft of net pay in these zones, which were
    subsequently perforated and stimulated and are now producing
    approximately 3 MMscfd.

    Latin America

    Revenue of $863 million increased 13% sequentially and 37%
    year-on-year. Pretax operating income of $204 million increased 14%
    sequentially and 58% year-on-year.

    Sequential revenue growth was primarily driven by a continuing
    ramp-up in Integrated Project Management (IPM) activity. A higher rig
    count coupled with stronger demand for Drilling & Measurements,
    Artificial Lift Systems and Schlumberger Information Solutions
    technologies in the Peru/Colombia/Ecuador GeoMarket also contributed
    to growth.

    Pretax operating margin increased sequentially to 23.7% as a
    result of an increase in exploration-related higher-margin Drilling &
    Measurements services in Peru/Colombia/Ecuador and a more favorable
    activity mix on IPM projects.

    In Colombia, the National Hydrocarbon Agency awarded Schlumberger
    implementation of a state-of-the-art solution for stereoscopic
    visualization and collaborative immersion using Petrel*
    seismic-to-simulation software.

    In the Mexico/Central America GeoMarket, Schlumberger performed
    the first StageFRAC* multistage fracturing and completion operation in
    Latin America. Part of the Contact* family of staged fracturing and
    completion services, StageFRAC delivers effective stimulation of
    multi-layered reservoirs ensuring optimal treatment of each zone,
    while reducing total treatment time. This marked the first time that a
    well was completed with the StageFRAC system outside North America.

    In Mexico, Pemex ran the Sonic Scanner advanced acoustic scanning
    tool and the Rt Scanner triaxial induction tool in combination on a
    deep-water well, revealing a significantly larger gas zone than
    previously expected. The radial profile acquired by the Sonic Scanner
    identified additional production from a zone the customer previously
    thought uneconomical.

    Europe/CIS/Africa

    Revenue of $1.69 billion increased 5% sequentially and 28%
    year-on-year. Pretax operating income of $495 million increased 7%
    sequentially and 38% year-on-year.

    Sequential revenue growth was driven by seasonally higher activity
    levels on land and offshore in the East Russia GeoMarket; increased
    demand for IPM services and for Artificial Lift Systems products in
    South Russia; higher demand for Drilling & Measurements technologies
    in North Russia; and the impact of the consolidation of
    Tyumenpromgeofizika. Increased demand for Well Services and Drilling &
    Measurements technologies in North Africa; higher demand for
    Artificial Lift Systems products in Continental Europe; and stronger
    demand for Wireline and Well Testing technologies in West and South
    Africa also contributed to growth. However, this was partially offset
    by project slowdowns in Nigeria and the Caspian, and by lower activity
    in Libya.

    The Area pretax operating margin increased by 50 basis points
    (bps) sequentially to reach 29.2% driven primarily by increased demand
    for higher-margin Well Services and Drilling & Measurements
    technologies in North Africa and a more favorable activity mix in the
    Russia GeoMarkets. This performance was partially offset by the
    project slowdowns in Nigeria and the Caspian and by lower demand for
    higher-margin Wireline and Drilling & Measurements technologies in
    Libya.

    Offshore Norway, Schlumberger performed a complex formation
    evaluation program on the high-pressure, high-temperature Onyx South
    West appraisal well for Norske Shell using the new Wireline InSitu
    Density* fluid characterization service. A member of the InSitu
    Family* of quantitative fluid properties measurements, the advanced
    technology was deployed on state-of-the-art wireline cables rated to
    500 deg F using a high-tension capstan.

    In Russia, the Sakhalin Energy Investment Company (SEIC) awarded
    Schlumberger a multi-well intelligent completions contract for the
    supply of downhole flow-control valves, permanent gauges and
    distributed temperature systems for the SEIC Piltun Astokhskoye B
    platform. The work scope comprises water injection wells scheduled to
    be drilled and completed offshore Sakhalin Island over the next three
    years. Plans for each well include a three- to four-zone intelligent
    completion.

    In North Russia, FiberFRAC* fiber-based fracturing fluid
    technology was introduced for Gazprom neft (Sibneft-Noyabrskneftegaz).
    The application resulted in a production increase of more than 20%
    over that achieved with current hydraulic fracturing techniques.
    FiberFRAC technology allows customization of fracturing fluid
    properties for varying reservoir conditions and enables optimization
    of the stimulation design and treatment leading to improved
    production.

    Elsewhere in Russia, Schlumberger was awarded a contract for more
    than 400 electrical-submersible pump systems. These systems will be
    manufactured in the Schlumberger Russia manufacturing facility located
    in Tyumen, Western Siberia.

    In the UK sector of the North Sea, Venture Production plc deployed
    the first FlexSTIM* modular skid-mounted stimulation package capable
    of large-scale fracturing operations. Installed on a supply vessel,
    the system placed multiple-propped fracture treatments in a horizontal
    gas well. Following stimulation, the well tested at rates approaching
    50 MMscfd--providing the customer additional production of more than
    9,000 barrels of oil equivalent per day, including associated gas
    condensate. The FlexSTIM technique offers an alternative to leasing a
    dedicated stimulation vessel.

    In West Africa, operators Total, Eni and Sonangol adopted
    integration of Schlumberger Wireline Scanner Family and Quicksilver
    Probe* rock and fluid characterization measurement technologies for
    thin-bed reservoir exploration and reservoir studies where analysis of
    fluid properties and distribution is complex--effectively minimizing
    risk and maximizing reserves.

    Middle East & Asia

    Revenue of $1.23 billion increased 1% sequentially and 28%
    year-on-year. Pretax operating income of $438 million increased 2%
    sequentially and 42% year-on-year.

    The sequential growth in revenue resulted from higher activity in
    the China/Japan/Korea, Indonesia, Australia/Papua New Guinea, India,
    Brunei/Malaysia/Philippines and Gulf GeoMarkets. This growth was
    partially offset by lower activity in Qatar and Thailand/Vietnam.

    Pretax operating margin increased sequentially to 35.7% driven by
    the activity mix in China/Japan/Korea; increased demand for
    higher-margin Drilling & Measurements and Well Testing technologies in
    Australia/Papua New Guinea; and higher demand for Wireline and Well
    Testing technologies in Brunei/Malaysia/Philippines. This performance
    was partially offset by the slowdown in the Thailand/Vietnam
    GeoMarket.

    In the Middle East, as part of a deep-reading technology
    collaboration project with Saudi Aramco, Schlumberger conducted the
    world's deepest cross-well electromagnetic survey in the Ghawar
    field--the world's largest oilfield--using the Electromagnetic Imaging
    technique that provides reservoir scale measurements to map fluid
    distribution. Although it stands as the deepest-reading survey
    completed to date, the key achievement was the well separation, which
    was in the range of 860 meters.

    In Saudi Arabia, Saudi Aramco selected StageFRAC multistage
    fracturing and completion technology for a staged-acid fracturing
    treatment in a 5,000-ft openhole section in an oil well in a carbonate
    reservoir where seven intervals were stimulated and tested in one
    trip. Post-treatment evaluation indicated that production doubled.

    In the United Arab Emirates, increased activity and strong
    customer-support services led to an increase in the number of ECLIPSE*
    reservoir simulation software licenses purchased by the Abu Dhabi
    National Oil Company. ECLIPSE advanced technology enables oil and gas
    customers to better simulate reservoir behavior over the life of the
    field.

    In China, Schlumberger Drilling & Measurements PeriScope 15*
    technology was deployed for the PetroChina Xinjiang Oil Company to
    enable placement of six horizontal wells in the sweet spot of a
    heavy-oil reservoir while staying within two meters of the undulating
    reservoir bottom contact. Use of this technology resulted in an
    average reservoir contact of 98%.

    Third-quarter revenue of $794 million increased 19% sequentially
    and was 20% higher compared to the same period last year. Pretax
    operating income of $306 million increased 42% sequentially and 32%
    year-on-year.

    Sequentially, Marine revenue increased due to higher vessel
    utilization following seasonal transits and scheduled dry dock
    inspections in the prior quarter, full-quarter utilization of the
    seventh Q* vessel, and improved pricing for conventional and Q-Marine*
    surveys. Data Processing revenue also increased driven primarily by
    higher sales in Europe, North America and Asia. These increases were
    partially offset by lower Multiclient sales while Land activity
    remained flat.

    Pretax operating margins increased by a robust 611 bps to reach
    38.6% driven by higher operating leverage in Marine and higher-margin
    Data Processing activities.

    Shanghai Petroleum Co., Ltd. awarded WesternGeco the first
    Q-Marine acquisition survey in China, which was completed in August
    using the vessel Geco Searcher to cover an area of more than 380 sq
    km.

    In Mexico, Pemex awarded an integrated Q-Marine acquisition and
    processing survey covering 7,050 sq km of the Temoa field. Acquisition
    began in July 2007 and is expected to be completed in December 2007.

    In Africa, Petrobras awarded WesternGeco an integrated Q-Marine
    acquisition and processing survey to cover 1,200 sq km in Angola Block
    6. The survey was completed ahead of schedule.

    WesternGeco recently completed a 1,100 sq km 3D land seismic
    acquisition project for Abu Dhabi National Oil Company in South East
    Abu Dhabi. The survey area consisted of 180-m high sand dunes and the
    survey was completed three months ahead of schedule.

    During the quarter, Schlumberger acquired a minority interest in
    PetroMarker, a Norwegian-based developer of marine electromagnetics
    measurements and interpretation technology. This acquisition will
    complement the WesternGeco integration of seismic and electromagnetics
    services designed to introduce a step change in reservoir definition.

    In the US Gulf of Mexico, WesternGeco announced the expansion of
    the E-Octopus wide-azimuth towed-streamer survey with the fourth and
    fifth phases scheduled to commence in January 2008. These surveys
    offer the unique advantage of more precise base and edge-of-salt
    definition through multi-measurement constrained imaging--the
    integration of magnetotellurics, gravity and Q-Marine data. As part of
    the E-Octopus survey, WesternGeco has developed the world's first
    onboard prestack wave-extrapolation (WEM) depth migration using
    proprietary Q-Xpress* techniques to provide quick-look migrated data
    volumes for interpretation, quality control, illumination, and to meet
    in-fill acquisition requirements. The E-Octopus final deliverables
    will include the latest state-of-the-art technologies such as
    anisotropic multi-azimuthal tomography, wavefield extrapolation
    demultiple and shot domain WEM with angle gathers.
