Rotary Steerable Systems for RealTime Drilling
• Traditional directional
drilling
– Points the bit from surface
– Rotates only the bit
– Pushes and slides the drill
string
• Rotary steerable drilling
7
– Sends the desired direction to
the drilling tool downhole
– Rotates the entire drilling
string
– Steers the well by configuring

VSAT
• ''A VSAT', for Very Small Aperture Terminal, is a
2-way satellite ground station with a dish antenna
that is smaller than 3 meters, as compared to
around 10 meters for other types of satellite
dishes.
• Schlumberger Oilfield Research co-developed
the world's first VSATs with Hughes Aerospace in
1985, to provide man-portable network
connectivity for oil field drilling and exploration
units. VSAT's are still used at well sites today to
transmit real-time data back for processing.

Challenges
• Workflows
• IT Infrastructure
• Business Model
14 Initials
Workflows that Work
• Managers need a clear idea of how to gain the
benefits of implementing a real time or e-Field
project
• The choice of sensors, data, bandwidth,
applications, people, and processes must be
driven by the oil and gas production problem to
be solved
15 Initials
Ready to Run
• IT infrastructure must provide
– End-to-end security
– Interaction with data in the right time
– Integration with other data and systems
– Solutions for presentation and evaluation
– Capability for collaboration
• IT infrastructure implementation must be reliable
and repeatable
16 Initials
Business Models
• Centralized model
– Little control or flexibility
– Obstacle when business units do not see initial
benefits
– Simple to administer
• Decentralized model
– Totally flexible
– Business units can choose resources based on
needs
– Highly inefficient
17 Initials
Business Model that Makes Sense
• Combination Approach
– Common costs reallocated to the business units
– Business units can purchase products and
services as needed
– Transitions to a pay per usage based on needs

•
The industry is on the right path to
the vision
Progress has been made but it will
take time to get there
– O&G technology exists
– IT exists
– Processes exist
– Funding exists
What is missing
– Understanding the benefits for
the workflows
– Reliable, repeatable IT enablers
– Business model
