and reduce drilling system shock and vibration. As one
of the critical tools employed in the Schlumberger
PetroTechnical Engineering Center (PTEC) network,
each drilling system is submitted to rigorous design
evaluation with a detailed application analysis of how
the system will perform for a specific drilling program.
The Drilling Group product lines are acutely aware
that one badly integrated part of the drilling assembly
can lower the performance of the whole. To prevent
this, drilling information is digitally integrated with
petrophysics and geology domain expertise through the
Petrel and Techlog platforms to provide critical well-
bore modeling and analysis capability. The integration
of key drilling data with the subsurface model using
high-quality measurements bridges the Schlumberger
drilling and reservoir characterization workflows to
ensure that the whole is greater than the sum of the
parts. The resulting drilling systems can achieve the
well integrity and accurate well placement that cost-
effective well construction demands. For example, the
slimhole PowerDrive Archer* high build rate rotary
steerable system in combination with Scope* MLWD
services and customized Smith drill bits is delivering
substantial performance gains that have significantly
lowered well construction cost in fields as widespread
as China, Argentina, Poland, and Australia.
Optimizing Production Technologies
Once a well is drilled, it must be produced. Long
gone are early industry production techniques of rely-
ing on natural drive assisted by simple rod pumps to
bring the oil to the surface. To help customers optimize
production and improve recovery, the Schlumberger
Production Group brings together the technologies of
reservoir stimulation, well completion, artificial lift,
production monitoring, and well intervention. Each
product line meets specific needs and also integrates
seamlessly across the Schlumberger product groups.
The workflow for unconventional reservoirs is a good
example of how synergy within and between product
lines can fully optimize asset performance. The hydro-
carbons must be unlocked from the reservoir and their
flow into the well facilitated. Maximizing the flow rate
and recovery depends greatly on stimulation technolo-
gies such as hydraulic fracturing, in which specially
engineered fluids are pumped at high pressure and high
rate into the interval to be treated, causing minute frac-
tures to form flowpaths in the reservoir rock.
Integrated drilling engineering and modeling is assured through a
network of more than 20 Schlumberger PetroTechnical Engineering
Centers around the world. PTEC locations combine all existing
drilling domain expertise from the Drilling Group product lines
with relevant subsurface geology and geophysics expertise from
Schlumberger PetroTechnical Services in one place. Each PTEC is
integrated with a real-time operation support center, and they are
often directly linked to customer offices or able to accommodate
customer personnel who wish to follow their projects. The worldwide
PTEC network is staffed by more than 400 experts working 24/7.
A PTEC manager coordinates cross-product-line services and actively
supports any required technical sales effort. PTEC experts design an
optimized, engineered drilling system for each specific customer
application, taking into consideration all available information, and
incorporating contingencies for identified risks. During operations,
the real-time operation center provides continuous support and
captures information to improve subsequent operations, processes,
and technologies.
Specific focus is placed on strengthening our subsurface and drilling
domain expertise, thereby further developing Schlumberger modeling
and engineering technology capabilities and integrating
these into fit-for-purpose drilling processes and work-
flows that are able to meet customer needs.
Integration of Drilling Engineering and Modeling
The multi-Z salt interpretation workflow in the Petrel E&P
software platform is used by the multidisciplinary teams of the
Schlumberger PTEC network to develop accurate 3D models for
reducing risk and improving exploration success in complex
deepwater pre- and subsalt deepwater reservoirs.
