Fields and Discoveries Database
|
More than 24,600 discoveries have been described in detail in the Discoveries and Fields database. This is the most comprehensive database with a total of almost 51,500 reservoirs described by its main characteristics like:
- Reservoir depth and thickness, hydrocarbon column and Gas-Oil-Water contacts
- Lithology, porosity, permeability, water saturation, GOR, salinity
- Reservoir age depositional environment, play type
- Trap type and seal, fluid and drive system, reservoir pressure and temperature
- Hydrocarbon composition like oil type and gravity, gas composition, contaminants like sulphur, nitrogen, CO2, etc.
- Oil, gas and condensate reserves with in-place and recoverable figures by reservoir
Some 10,300 of the discoveries are currently producing and 1,870 fields have been abandoned. For these fields, in addition to the detailed reservoir description above, the following information is available:
- Details of operator and partner interests
- Discovery and drilling history
- Field development scheme and description
- Platform information like type, height, weight, slots
- Cost estimates of development, service contractor information
- Well statistics: number of producing oil / gas wells, injectors, depleted wells
- Annual production
- Reserves history of in-place and recoverable reserves with a breakdown in proven, probable and possible reserves

Illustrations of top structure maps of reservoirs, composite logs of hydrocarbon-bearing intervals, structural cross-sections, development schemes, etc., form an important part of the database. Some examples include:

Monthly production data forms part of the Discoveries & Field database. In addition to the 20,500 annual production figures, the monthly database contains a total number of 1,481,901 volumes. Monthly figures in particular can help to better understand the field history. For example, periods of reduced production because of workovers, or seasonal variation in supply (DCQ) as is shown in the example from North Sea below.
