Our portfolio of innovative products reflects Schlumberger's investment in R&D. Engineering in these disciplines continues to expand the operational boundaries for E&P.
Systems that transmit information about the subsurface during drilling enable operators to reduce operational risk and place boreholes for optimal recovery of reserves. Examples of telemetry and surveying projects include MWD tools and their survey systems; mud-pulse and electromagnetic telemetry, as well as new transmission concepts; and the surface systems and communication networks needed to support MWD and LWD services on site.
Understanding a reservoir is crucial for making decisions about its production and management. Projects that further in situ reservoir characterization focus on technology and processes that provide information through fluid and rock samples and pressure and permeability measurements—in conventional and unconventional reservoirs. Recent innovations for wireline sampling include the award-winning Quicksilver Probe technology.
Much of what is initially known about a subsurface formation is learned by using resistivity, nuclear, and NMR tools to measure properties such as porosity, fluid type, fluid saturation, density, movable fluid, lithology, and permeability.Advances in formation evaluation result from breakthroughs in tool designs, measurements, and data interpretation. An example is the PeriScope geosteering LWD tool. It optimizes placement of high-angle and horizontal boreholes through a deep-reading, directional electromagnetic measurement that estimates the distance to bed boundaries or to fluid interfaces.
Most software projects involve applications for the wellsite, such as data acquisition, control, and processing; log generation; and generation of digital products based on data from downhole tools. But there are also office-run applications, which provide answer products to assist with interpretation of wellsite data.
Cables are integral to many oilfield services, providing a means both to convey tools and transmit data. Design and manufacture of wireline and seismic cables take place at the Sugar Land campus, and specialty cables are available for purchase by customers with interests in drilling, oceanographic, and subsea operations. In addition to cables, projects also include development of systems to convey wireline tools within the borehole, either before or after casing is installed. These include coiled tubing systems for highly deviated or horizontal wells and tractors for difficult logging environments.
Improving wellsite efficiency is a key focus in the development of surface equipment for stimulation, cementing, and coiled tubing operations; wireline logging trucks; trailers; and offshore skids.The PodSTREAK unit is a model example of improved efficiency in fracturing operations. It acts as a command center from which almost all onsite fracturing equipment can be remotely controlled, and its design accommodates 70% of all treatments.
Development of acquisition and control systems for logging, stimulation, cementing, and coiled tubing services includes both hardware and software projects. Remote wireless network software and control systems enable data acquisition, job monitoring, and automation and control of surface equipment and downhole tools.
Stimulation-treatment-design applications are based on complex numerical models. Such applications assist in the design, evaluation, and optimization of stimulation services. Projects in this discipline also involve designing software to streamline Schlumberger service-delivery processes.
Experts in chemistry and formulation engineer fluids that improve hydrocarbon production and minimize water and sand production. Cost-effective solutions for fracturing and matrix acidizing, gravel-pack placement, and water control are a key focus.
ThermaFOAM High Temperature CO2 Fracturing Fluid systems for high-temperature CO2 wells and CleanGEL hydrocarbon-free polymer-based fracturing fluids for coalbed methane production offer solutions to two of today's unconventional challenges.
