The dream is a reality: Mr. Hassan A. Rahim, Section Head PSG & Oil Team, inspecting
new wellhead instrumentation along with Ms. Lai Chan Chiu, Schlumberger KwIDF Project
Manager, and Mr. Juan Carlos G. Bonilla, Schlumberger Change Management Consultant.

Overview
Schlumberger and KOC are partnering to provide the
intelligence and technology that will virtualize the
North Jurassic gas field. This solution answers the
design and equipment needs of a sophisticated data
delivery infrastructure that KOC will enjoy well into
the 21st century.
Project scope
Mr. Hassan A. Rahim says, “This is an exciting
project for us, as it is the very first of its kind in
terms of size and scope. We are installing everything
from wireless sensors at the wellsite, to routers
Field Control Room
Telecom tower
Operator station
and long-range wireless, remote monitoring
systems, to a CCTV video surveillance system that
communicates from the wellhead to the field control
room and KOC offices.” He adds, “State-of-the-art
digital components will bring field data all the way
to the new Collaboration Center, where it can be
integrated into Schlumberger software technology,
feeding critical well information directly to pertinent
engineering workflows in real time. The operations
data can be viewed at high-tech workstations or
projected onto large, 3D, wall-mounted screens.
It’s a big change from the old methods of data
capture and delivery!”

Project requirements
Specifying the KwIDF Jurassic requirements and
implementing the digital network solution was a
joint effort accomplished by KOC’s IT department,
Schlumberger Information Solutions (SIS), and
vMonitor technical engineers. Mr. Rahim explains,
“We were determined to create a scalable system
to satisfy the company’s data acquisition needs
today and in the future. Wireless connectivity and
solar power are just two examples of the emerging
technologies applied to the KwIDF Jurassic project.
Down to the nuts and bolts of the control panels
and battery backups, all items were chosen and
configured to meet KOC’s desire for continuous
remote, real-time data monitoring of this particularly
hazardous location.”
Field instrumentation and software
Mr. Rahim informs, “With the new field
instrumentation, it will be possible to collect and
transmit real-time data by monitoring gas leaks,
H 2
S, and pressure at the wellhead, in addition to
monitoring corrosion and temperature of the flowline
24/7/365.” Other innovative features include the
ability of the hydraulic control panel to support
remote supplementary controls using solenoid valves
and to optionally provide remote control of hydraulic
pumps. Then, there is the new remote terminal unit
(RTU) that will support multiple analog and digital
inputs and outputs, multiple thread multi-tasking
applications, IEC-61131 ISAGraf PLC programming
languages, customized ESD logic, and data logging
…to name a few.
TotalAccess software from vMonitor will provide a
user-friendly, onscreen console to view various types
of data monitoring activities, including field
measurement gauges, data polling graphs, and
summary information of surface instrumentation data,
such as pressure and flow rate, for a particular well.
Digital, wireless connectivity
According to Mr. Rahim, “The entire infrastructure
is linked together via a WIMAX network connection
to a telecommunications tower, which passes data to
a field control room that houses the operator station
with router, firewall, switch, etc. that connects to
KOC’s Intranet using thin client technology.”
Disaster recovery
Included in the overall solution is a Disaster Recovery
room, complete with a redundant server and SQL
fault server, as well as a real-time database (RTDB),
real-time data polling engine (DAQ), and a Historian
database for archival purposes, making this a true
end-to-end solution. n
