The Huldra Case
9
Huldra Development

• Will be developed as a NNM well-head platform
  with a first stage separator, liquids to
  Veslefrikk and gas to Heimdal
• All wells will be equipped with multiphase meter
  and sand monitoring system
• All wells will have downhole PT gauges
• Choke positions will be remotely monitored

10
Huldra Data Acquisition

• Measurements
• Bottom-hole Pressures Temperature
• WellHead Pressure Temperature
• Meter FlowRates
• Meter Pressure and Temperature
• Sand Production
• Choke Positions
• Automatic Import
• PROSTY allocated rates
• Manual Import
• Eclipse Simulation
• PVT Tables
• Vertical Lift Tables

Data will be available real-time using DACQUS to
Huldra asset team in Bergen (or anywhere else
and partner offices)

Huldra IRPM Suite

• Huldra IRPM suite consists of following modules
• DACQUS
• Data Acquisition (time series)
• Visualization
• Mathematical Operations on time series
• Qtotal Q1 Q2 ...Q6
• BHP VLPLookUp(THP,Qo,Wct,Gor)
• Time shifting to compare transients from a common
  time datum
• Sand production indicators, hydrate formation
  indicators
• Basic Engineering Analysis
• WellTest
• Analysis of transient data
• History of well multirate tests
• GAP Link (VBA script running GAP from Petroleum
  Experts)
• Field optimization software

IRPM Challenges

• Technology should apply to dumb as well as
  smart fields
• Easy common interface
• Ability to connect to different optimization
