PRESENTATION

• Shearforce is pleased to provide our Commercial
  Proposal and a Technical Description regarding a
  field-proven, Leak Detection and Location
  System (LDS) for the NNPC Crude Oil and Product
  pipelines.
• Shearforce Nigeria Ltd. is an indigenous Nigerian
  Company formed with proper alliances with
  technical partners to provide complete turnkey
  projects. Similar installations of projects
  completed by these partners are located in this
  presentation.

SOCIO-ECONOMIC IMPACT BENEFITS

• 1 Greatly enhance the security of the pipelines
  through the immediate detection of any sabotage
  attempt.
• 2 Verification of production figures presented
  by the Oil Companies thereby supporting Mr.
  Presidents Implementation of the EITI
  (Extractive Industries Transparency Initiative.)
• 3 Immediate detection of attempts at illegal hot
  oil taps thereby allowing the Rapid Response
  Team a window of up to six hours in which to
  prevent completion of the hot taps.
• 4 Detection of exact location (within one meter)
  of leaks in remote areas and underground pipes
  which would normally go un-noticed.
• 5 Reduction of environmental damage due to oil
  leaks since the health and integrity of the
  pipeline can be determined.

INTRODUCTION

• The LDS proposed provides the best of all
  technologies, offering superior performance by
  utilizing multiple methodologies, for multi-phase
  or complicated underwater networks the system
  would incorporate
• 1 Rigorous mathematical/model-based modeling
  using both mass balance and pressure transient
  analysis in the pipeline.
• 2 Comprehensive statistical signal trend
  analysis and
• 3 State-of-the-art dynamic leak "fingerprint"
  pattern- recognition algorithm.
• The LDS pattern-recognition technology is
  particularly important for pipelines with limited
  instrumentation or where spacing between
  measurement points can be very large.
• The LDS will provide very accurate within one
  meter detection and determination of leak
  location even in very large, complicated
  multiphase networks.

INTRODUCTION

• The LDS proposed provides the best of all
  technologies, offering superior performance by
  utilizing multiple methodologies, for
  single-phase or straight forward networks the
  system would incorporate
• 1 Computational Pipeline Monitoring with time
  tested practicality using both mass balance and
  pressure transient analysis with proven API
  provided algorithms.
• 2 Comprehensive flow and pressure deviation
  analysis and
• 3 State-of-the-art dynamic leak Analyzer
  calculations.
• The LDS will provide very accurate within one
  meter detection and determination of leak
  location even in very large, complicated
  multiphase networks.

SYSTEM DESIGN

• Through the use of Internet Satellites, Real Time
  Alarms and Reporting of any leak will be
  available to any official or person issued with
  valid frequently changed security code.

SYSTEM DESIGN

• PICTURE BELOW SHOWS SATELLITE INTERNET
  CONNECTION. PICTURE ON TOP RIGHT IS REMOTE
  TERMINAL UNIT CONNECT TO PIPELINE. PICTURE LOWER
  RIGHT IS DENITY METER.

SYSTEM DESIGN

• Several screens will be used to show the complete
  pipeline system in detailed map form with exact
  global positioning system (gps) co-ordinates of
  any leak.
• The primary control room will have a complete
  monitoring and control center. Each manned depot
  and receiving station will also have a monitoring
  station.
• An independent monitoring station will be
  established by Shearforce in Abuja.
• All monitoring stations will be a state of the
  art server based systems communicating directly
  via satellite.

11
IMPLEMENTATION OF SYSTEM

• The implementation of the following system can be
  divided into several logical areas as follows
• Phase 1 Detailed study and physical survey
  of complete pipeline network.
• Phase 2 Engineering of System.
• Phase 3 Testing of System.
• Phase 4 Installation of Hardware, Start-up in
  Sections.
• Phase 5 Installation of Monitoring Stations
  Inc.Software
• Phase 6 Operation of System

12
IMPLEMENTATION OF SYSTEM

• The Sections are defined as identifiable segments
  of the pipelines as indicated on the map at the
  end of this presentation.
• Twenty Four Product Sections and Six Oil
  Sections.
• Note that a test section from Port Harcourt to
  Aba can be installed in two-three
  months.            

13
EXPECTED USE OF INFORMATION

• REPORTS OF ANY OIL LEAK OR ATTEMPTED HOT TAP WILL
  BE RELAYED TO A RAPID RESPONSE TEAM.
• WE RECOMMEND THAT RAPID RESPONSE TEAMS BE FORMED
  BY GOVERNMENT DRAWING PERSONNEL FROM ITS
  SECURITY AND MILITARY APPARATUS.

• 3Kender Morgan-Central Florida Pipeline-Recently
  purchased a pipeline license for an additional
  pipeline. Both Pipelines cross environmentally
  sensitive areas of Florida (passes next to
  Disneyland). Pipeline no. 1 is a 47,000 bbl 87
  mile 10 pipeline. The additional pipeline is a
  132,000 bbl 105 mile 16 pipeline (this pipeline
  is showcased in Pipeline Gas Industry magazine
  June 1996 article enclosed). Contact Dawn

• 5 Valero-There are 14 product pipelines
  covering approximately 4000 miles. The first
  system was a test system and was on a 408 mile
  product pipeline which carried multiple products
  from propane to diesel 225000 bbls, over severe
  terrain. This system was installed in 1999.
  Since then 18 more systems have been added. One
  of the systems is an LPG system. Valero is very
  happy with this system and purchased another
  system for there Crude system which has 5 crude
  pipelines. Lonnie Ayres 210-627-2516

  to corrosion, fatigue etc.
• LDS is a very sophisticated yet competitively
  priced system with a pay back period of twenty
  days..
• LDS will determine the exact locations of
  underground leaks prior to reaching the surface.
• LDS will use wrap around type flow meters and
  will utilize existing pressure taps at the
  manifolds thus eliminating the need for hot-taps.
  
• Verification of production figures presented by
  the Oil Companies thereby supporting Mr.
