FIELD NAME

This gives the name of the field as well as alternate or previous names where applicable. Note infield uses Romanised alphabet but not English translations of foreign names i.e Snoehvit not Snowhite

Possible problems in finding fields could be caused by:

Use of an English name as against the local equivalent. See above.

Searching using a name identifying a prospect or geographical area rather than the field name itself.

OPERATOR NAME

The local name of the operating company or consortium is always used. Thus Shell Nigeria against just Shell. By using *Shell* when searching will return all operating companies with Shell in their name.

For information on consortiums please refer to the operators file for a full list of the various consortium members.

DATE/YEAR DISCOVERED

This is when the discovery was announced

DATE/YEAR ON STREAM

Date of first production. For future fields this can alter frequently as plans are changed.

DEPLETION DATE/YEAR

This is the currently announced date of the end of production. Note improvements in recovery technology will affect this, as will variations in the price of oil.

FIELD LIFE (NUMBER OF YEARS)

A function of Year on Stream and Depletion year.

WATER DEPTH (METRES)

The average water depth over the field.

LOCATION

For fields in the Gulf Of Mexico and the North Sea this is the block number. Elsewhere this is the longitude and latitude down to the nearest minute.

Please note the semicolon (;) at the end of the longitude and latitude numbers is there to prevent an automatic conversion of the numbers into a date when data is exported to MS Excel.

STATUS (fields file)

• PRODUCING : Field is onstream producing oil, gas or condensate.
• UNDER DEVELOPMENT: Platform or subsea completions are being constructed and pipelines laid.
• FIRM PLAN : Development plan (PDO) submitted to relevant authority.
  
• PROBABLE : Development planning stage at company level.
  
• POSSIBLE : Very early stage of field evaluation.
  
• DEFERRED : Cancelled project.
  
• ABANDONED : Production completed, facilities removed.
  
• SUSPENDED : Production facilities in place, but production is shut-in at present.
  
• NEVER PRODUCED: Small find never developed.
  
• LICENCE SUSPENDED: Abandoned fields, all facilities removed licence returned to licensing authority.

RESERVES

• TOTAL (TONNES OF OIL EQUIVALENT)
• OIL (MILLION BARRELS)
• GAS (BILLION CUBIC FEET)
  
• CONDENSATE (MILLION BARRELS)

All reserves are the proven plus probable figures for the field. This is the economically recoverable reserves that will probably be recovered over the life of the field. Changes in this figure are often upward revisions as improvements made in enhanced recovery technology occur. Note these figures are not reserves in place.

90% Probability = P90 = Proven Recoverable Reserves
i.e. there is a 90 per cent chance that the actual quantity will be more than the amount estimated as "proven" and a 10 per cent chance it will be less.

50% Probability = P50 = Probable Recoverable Reserves
i.e. there is a 50 per cent chance that the actual quantity will be more than the amount estimated as "proven and probable" and a 50 per cent chance it will be less.

The conversion rates used are as follows

Conversion ratios can vary depending on the API of the oil.
Infield uses

1 tonne crude oil = 7.5 barrels (bbls)
1 cubic metre (cm) =35.31 cubic feet
1 cubic metre =6.29 barrels (Conoco for their Statfjord field use 6.28)
1 cubic metre of gas = 0.36 therms
1 tonne fuel oil =406 therms
1 billion cubic metres (bcm) of gas = 0.83 million tones of oil equivalent
1 billion cubic feet (bcf) of gas = 0.176 million barrels of oil equivalent (mboe)
1 trillion =1000 billion

Note: an E next to any of the specific oil/gas /condensate figures indicates that this an estimate derived from the Total reserves

PRODUCTION RATES

• OIL (BPD = Barrels Per Day)
  
• GAS (MMCFD = thousand thousand / million cubic feet per day)
  
• CONDENSATE (BPD)

Indicates the volume of production from the field.

For producing fields this is the latest available figure or the average of the last years production. For future fields this is the currently announced production rate. Where no development scheme has been announced yet this is the expected rate if this field goes into production.

DEVELOPMENT TYPE

• FIXED PRODUCTION PLATFORMS ONLY
  
• FIXED PRODUCTION PLATFORM AND SUBSEA
  
• EXTENDED REACH DRILLING
  
• FLOATING PRODUCTION:
  Includes TLPs and spars and assumes subsea component with FPSOs and semi-sub based systems
  
• FIXED & FLOATING PRODUCTION
  
• SUBSEA SATELLITE TO FIXED PRODUCTION
  
• SUBSEA SATELLITE TO FLOATING PRODUCTION
  
• SUBSEA SATELLITE TO ONSHORE FACILITY
  
• FIXED PLATFORM OR SUBSEA (ALTERNATIVE)
  Indicates there is also an alternative plan currently under consideration
  
• FLOATING PRODUCTION OR SUBSEA (ALTERNATIVE)
  Indicates there is also an alternative plan currently under consideration
  
• NO DEVELOPMENT SCHEME ANNOUNCED YET
  
• NO LONGER ON STREAM
  
• EXTENDED REACH DRILLING AND/OR SUBSEA
  Testing may lead to need for a further well.
  
• EXTENDED REACH DRILLING AND PLATFORM
  Successful testing made lead to need for a small satellite platform
  
• FIXED & FLOATING PRODUCTION AND SUBSEA
  Where there is a requirement for fixed wellheads, FPSO and subsea completions at differing stages of its development e.g.: Captain field in North Sea

HIGH PRESSURE/HIGH TEMPERATURE

• (YES OR NO)

Infield defines HP/HT as being temperatures of 150 degrees centigrade and over and / or a pressure of 690bar or 10,000 psi.
