CAVEATS AND DEFINITIONS
Data in Energyfiles is subject to the
following caveats and definitions. By using Energyfiles you signify
acceptance:
Production
Oil production rates - average unprocessed crude oil at surface
temperatures/pressures plus NGLs and processed synthetics from extra-heavy oil
and bitumen
Gas production rates - average sales gas at surface temperatures/pressures,
not including re-injected, flared or vented gas
Forecast output growth/plateau length/decline rate - rule of thumb based on
an actual/assumed production system/expected reservoir performance
Longer term production rates assume development wells drilled and secondary
recovery projects implemented as required
No
major disruptions to output for fiscal, social, climatic or emergency reasons
Reserves ultimately produced from a field do not necessarily reflect proven
reserves of the day, restricted by financial rules
Wells
Wells are deemed drilled in year of spudding except for pre-spudded development
wells which are drilled in year of re-entry
Development wells - include producers and injectors but do not include
appraisal wells converted to development
Sidetrack wells - are only counted if the intent is to acquire new data
and/or production
For
a few countries the number of historic wells drilled each year is very poorly
reported thus tabulated figures may be derived from general rules of thumb
Wells located in lakes and swamps (e.g. Maracaibo) are included in onshore
categories
General
We
have no access to confidential information and so cannot confirm that numbers
are always accurate
The
numbers given are historical estimates and forecasts often based on limited
published information
Some historical data are unknown or unobtainable; in these cases numbers have
been estimated based on trends and perceived potential
There is no guarantee that estimates or forecasts will prove to be accurate
Longer term forecasts are dependent on success (or failure) which is, by
definition, speculative
They may or may not compare with numbers provided by other analysts however it
is hoped that they will prove to be the best available
Disclaimer
No
representation or warranty, express or implied, is made as to the completeness,
accuracy or fairness of any information
No
responsibility is accepted in relation to such information, whether fact, or
whether opinion or conclusion that may be drawn
